High Renewable Energy Costs Damage the Vermont Economy
With regard to renewable energy, it DOES matter what Vermont does, especially if it is on the wrong track to the detriment of Vermont’s economy, which has been in an about 0.85% per year growth mode since about 2007, with declining real household incomes since about 2000, while state spending increased at a greater annual percentage.
As shown below, Vermont’s renewable energy programs, such as SPEED, are wasteful, because they produce energy at 3 - 4 times New England annual average grid prices, which is unsustainable, especially in a near-zero-growth economy. Scarce capital should be spent on increased energy efficiency, not wasteful renewable energy programs. It would be a much better way forward for Vermont, as it would reduce the energy bills of households and businesses.
Already-struggling households and businesses have been dealing with a near-zero-growth Vermont economy since 2007, with the tax-burdened, hollowed-out, private sector shrinking relative to the growing, bloated government sector, which is acting as a wet blanket on the private sector, a sure recipe for economic stagnation, lack of well-paid employment growth (except in government), or worse.
At some point, clear-headed thinking must prevail, budgets must be cut, taxes must be reduced, wasteful programs must be eliminated, or else Vermont's hollowed-out, private, tax-paying economy will continue on its near-zero-growth path, less and less able to scrape up enough money to pay for the rapidly-increasing expenditures of the growing, money-guzzling government sector.
HOUSEHOLD INCOMES, STANDARD OF LIVING, HOUSEHOLD ELECTRIC RATES
Declining Real Household Incomes: Real household incomes of the middle, 4th and bottom quintiles peaked in 2000, 2000, 1999, respectively; in those peak years their incomes were $56,311, $33,815, $13,663; in 2012 their real incomes were $51,179, $29,696, $11,490, for a decline from peak year of 9.1%, 12,2%, 15.9%. The bottom 60% of households with steadily declining real incomes! No wonder their part of the economy is in near-permanent recession.
Vermont Standard of Living: The Vermont cost of living is about 20% greater than of the US, whereas, in 2012, Vermont’s real household income was about 3% greater than of the US, meaning the standard of living in Vermont is already about 17% lower than in the US. See below data and URLs.
US: 2012, $51,371; 2011, $51,557; 2010, $52,703; 2009, $53,760; 2008, $55,484; 2007, $56,189; 2006, $55,176; 2005, $54,387
VT: 2012, $52,977; 2011, $53,878; 2010, $52,029; 2009, $55,256; 2008, $55,564; 2007, $55,266; 2006, $54,281; 2005, $53,733
Cost of Living Index, by state
Household Electric Rates: Vermont’s household electric rates used to be the lowest in New England, but have been rising faster than of other New England states and are now the 4th highest in the US, after Connecticut, Alaska and Hawaii.
Rates in November 2013, c/kWh, all taxes and fees included: VT 17.54, CT 18.21, Alaska 18.33, Hawaii 37.34
INCREASED ENERGY EFFICIENCY
Vermont would have a much bigger bang for the buck, i.e., reduce more CO2 per invested dollar, if it practiced increased energy efficiency, starting with:
- A strict energy code for NEW, subsidized, net-zero-energy buildings, instead of expensively subsidized renewable energy projects; there is no money to do both at the same time. Imposing new carbon taxes, increased EV surcharges, etc., thereby further harming Vermont’s weak economy, is not and option.
- Increased surcharges on electricity guzzling households; the greater the consumption, the greater the surcharge percent; the surcharge to be collected each month. Such households would quickly find ways to reduce their electricity consumption.
- Increased surcharges on gasoline- and diesel-guzzling light duty vehicles, i.e., cars, minivans, SUVs, ¼-ton trucks; the greater the gas guzzling, the greater the surcharge percent; the surcharge to be collected at time of annual registration. Such vehicle owners would quickly find ways to reduce their gas and diesel consumption, such as by driving fewer miles.
The above measures would quickly reduce CO2 emissions and raise revenues to subsidize weatherizing the housing of lower-income households and net-zero-energy buildings.
Energy-Efficient Housing a la PASSIVHAUS: Energy efficiency will go nowhere regarding buildings without a very strict, state-wide-enforced, building code. In Denmark, a recently passed law requires NEW residential buildings must be zero-energy. Vermont should follow THAT example.
Here is an example of what CAN be done, AND it would be invisible, AND it would maximize fossil fuel and CO2 reduction, AND it would REDUCE energy bills of already-struggling households and businesses!!!
If one had a house about as efficient as a Passivhaus, then energy requirements for heating, cooling, and electricity would be minimal, even in cold climates. For living off the grid, in a near-zero-CO2 mode, the house would need to be equipped with:
- A roof-mounted, PV solar system + a battery system for electrical energy storage + an electric heater in the hot water storage tank to get rid of any excess electricity, plus
- A roof-mounted, thermal solar system + a hot water storage system + a system to get rid of any excess thermal energy.
- A whole house duct system to supply and return warm and cool air, with air-to-air heat exchanger to take in fresh, filtered air and exhaust stale air at a minimum of 0.5 ACH, per HVAC code.
- For space cooling, a small capacity, efficient AC unit for space cooling would be required on only the warmest days.
- For space heating, an electric heater, about 1.5 kW (about the same capacity as a hairdryer) for a 2000 sq ft house, in the air supply duct, would be required on only the coldest days.
NOTE: As space heating and cooling would be required for just a few days of the year, an air-source heat pump would be excessive and too expensive.
NOTE: A future plug-in vehicle could be charged with DC energy from the house batteries by bypassing the vehicle AC to DC converter.
Efficiency Vermont Not Cost Effective: Efficiency Vermont spends about 45% of its budget on Salaries, Benefits, Payroll Taxes, etc., for its 180-person staff, plus General & Administration. The other 55% is used to subsidize energy efficiency projects. That is a very inefficient way to do energy efficiency. Some other way has to be found before the EV budget, apparently on autopilot, goes to the scheduled $85 million.
Whereas, EV year-end balance statements of the early years could be deciphered, this is not the case with the amalgamated Vermont Energy Investment Corporation year-end statements, unless a person is a very experienced CPA and has the statements explained to him by insiders.
Setting up EV and VEIC may have been attractive some years ago, but the actual results do not justify their continued existence. It would be best, if EV and VEIC were declared expensive, ineffective failures, and ALL the money (about $85 million/yr and increasing) used to subsidize weatherizing low-income housing and net-zero-energy buildings.
There would be no need to have a carbon tax, etc., and Vermont ratepayers would see about a 5% reduction in their electric bills due to the EV surcharge being ended!
Vermont builders were building net-zero-energy buildings before EV even existed. There is no need for EV to tell them how to do it.
In Denmark, ALL new housing must be net-zero-energy. Vermont should follow THAT example, instead of destroying ridgelines and coddling in-state and out-of-state multi-millionaires, with tax shelters, to build 2.2 MW solar plants in meadows, and have the PSB “compensate” them (fatten their tax shelters, at the expense of already-struggling households and businesses) at an outrageously high 25.7 c/kWh, whereas, according to David Hallquist, CEO of VEC, solar energy costs about 17 c/kW for 1,000 kW systems and up.
NOTE: Vermont's government makes lots of high-sounding pronouncements regarding energy efficiency, but does not practice it!!
Vermont State Government buildings: average 107,000 Btu/sq ft/yr for heating, cooling and electricity. Energy efficient buildings would use about 25,000 Btu/sq ft/yr. http://www.publicassets.org/PAI-IB0806.pdf
The Xerox Headquarters, Stamford, CT, placed in service in 1979, needs only 28,400 Btu/sq ft/yr for heating, cooling and electricity, without the benefits of PV solar panels, geothermal heating, or solar hot water heating. Nearby similar headquarters buidings needed at least 50,000 Btu/sq ft/yr.
VERMONT RENEWABLE ENERGY PROGRAMS ARE TOO EXPENSIVE
SPEED and non-SPEED Solar and Wind: By the end of 2013, Vermont had subsidized about $538 million of solar and wind investments (about $220 million for solar + about $318 million for wind), over the past 3.5 years, but had practically nothing to show for it; about 0.96% from solar and about 3.89% from wind, for a total of 4.86% of Vermont’s annual ELECTRICAL ENERGY consumption, or about 4.86/3 = 1.62% of ALL annual energy consumed by Vermont.
NOTE: The below report shows about 2.15% of Vermont’s workforce is engaged in the heavily-subsidized RE sector and 2.15% is engaged in energy efficiency. If it took 2.15% of the Vermont workforce to produce such a small RE result, then a much larger percentage of Vermont’s workforce would need to be engaged in the heavily-subsidized RE sector to reach 90% of ALL energy from RE by 2050, per the 2011 Comprehensive Energy Plan.
That 1.62% is a long way off from the unrealistic, starry-eyed, 2011 CEP goal of 90% of ALL energy from RE by 2050, not just electrical energy which is only 1/3 of ALL energy.
Regarding the 90% RE goal, that would require about 90% of all cars, SUVs, minivans and 1/4-ton pick-ups to be all-electric or hybrids using electricity and 100% bio-fuels. No more 90% gasoline/10% ethanol mix, or diesel, etc., at the pump. That implies the US will be producing at least 15 million/yr of such vehicles by 2050.
About 90% of all residential and other buildings would have to be heated and cooled with electric heat pumps and bio-fuels, such as wood, wood pellets, etc. No more fuel oil, propane, gas, coal, etc., for building heating and cooling.
That would require Vermont's annual ELECTRICAL consumption to increase by about a factor of 3, from about 5,600 GWh to 16,800 GWh, about 90% of it from RE.
By the end of 2013, Vermont had achieved 4.86% x 5,600 GWh = 272 GWh of RE by investing about $538 million over 3.5 years.
Vermont would have only 3 x 5,600 x 0.90 – 264 = 14,848 GWh to go to achieve 90% RE by 2050, if all of it were from Vermont-generated solar and wind.
NOTE: There are other Vermont-generated RE sources, but they are expected to be minor.
SPEED and non-SPEED Solar and Wind by 2050: Here is a hypothetical case to calculate the cost impact if the additional energy (14,848 GWh) were to be supplied by wind and solar by 2050 (assuming biomass, farm methane, geothermal, etc., will remain, minimal):
Solar would have to increase from 44 MW at end 2013, to 2,401 MW at end 2050, at a cost of $8.4 billion, based on an average SYSTEM price of $3.5 million/MW.
Wind would have to increase from 113 MW at end of 2013, to 6,167 MW at end of 2050, at a cost of $17.4 billion, based on an average SYSTEM price of $2.814 million/MW.
Over 2050 - 2013 = 37 years, the capital cost would be about 8.4 + 17.4 = $25.8 billion/37 years = $801 million per year, if all of the wind and solar RE were produced in Vermont, plus grid build-outs of about 15% x 25.8 = $3.9 billion, for a total of $29.6 billion.
NOTE: The 6,167 MW of wind turbines is equivalent to 98 Lowell Mountains. Sayonara Vermont!!
What employment % would it take for build-out of the RE effort from $538 million/3.5 = $153.7 million/yr to $801 million/yr?
Oh, about 2.15% x $801/$153.7 = 11.20% of Vermont’s workforce, plus at least 500 - 1000 additional government employees to oversee the RE part. Plus an approximately equal workforce percentage, investment and additional government employees would be required regarding the energy efficiency part.
Vermont’s RE build-out effort + the energy efficiency effort would involve about 2 x 11.20% = 22.40% of Vermont’s private workforce, plus about 1000 additional government employees,
Annual capital cost would be $801 million, Wind/Solar + $801 million, Efficiency = $1.602 billion/yr, for 37 years!!!
NOTE: All this would be in addition to the hundreds of additional government employees to oversee single-payer healthcare!!!
Based on the actual RE cost data of the past 3.5 years, the 90% RE goal would impose on Vermont's economy job-destroying household and business electric rates at least 3-4 times current levels!! For sure, IBM, et al., would lead the inevitable exodus from Vermont.
NOTE: PV panel prices are about as low as they will go. Roof-mounted PV SYSTEM costs have leveled at about $4000/kW. Wind turbines on ridgelines are more or less a dead issue in Vermont for the next 10 years, per Rep. Klein. Wind turbine technology is mature and increased efficiency can be achieved mainly by going taller, not likely on Vermont ridgelines. Regarding new technologies? They will be slowly implemented and at great cost, as Germany (way ahead of Vermont) has already found out during its 13 years of ENERGIEWENDE.
NOTE: Here is a speech to a PV solar stakeholder convention in Germany by Sigmar Gabriel, Vice Chancellor, and Economics and Energy Minister, regarding the Germany’s Renewable Energy project, ENERGIEWENDE, verging on failure. His speech was likely approved by Chancellor Angela Merkel.
The audience was stunned to hear the unvarnished truth regarding RE.
“The truth is that in all fields we under-estimated the complexity [and cost] of the Energiewende.” [Just as in Vermont].
it such a challenge for Germany, it would be even a greater challenge for less capable/less rich countries/states, including Vermont.
“The complete exemption from paying feed-in tariffs is a model that is wonderful for you (PV stake holders and PV system owners) as a business model, but is one that is a problem for everyone else.”
Well-off households with PV systems, and in-state and out-of-state multi-millionaires with risk-free tax shelters owning SPEED PV solar projects receive subsidies, generous feed-in tariffs, and other benefits, whereas other households, 97+%, pay the costs; a gross societal inequity, including in Vermont.
NOTE: It is likely that goal was set without any realistic, in-depth analysis, which should have been included in the 2011 CEP report for all to see. Poor Vermont’s goal is more extreme than rich Germany’s ENERGIEWENDE goal.
NOTE: It is amazing the Department of Public Service does not keep track of these numbers and post them, along with other project data, in spreadsheet format, on its website. Even for the expert, it takes quite some effort to gather the information from various sources.
NOTE: It would be wise to first construct about 2,000 MW of transmission lines to bring clean, low-cost, steady (not variable, not intermittent), renewable hydro energy from Labrador, New Brunswick and Quebec to Vermont.
The excess hydro capacity, MW, is already built. The environmental damage has already occurred. It would be beyond rational to do major ADDITIONAL environmental damage for RE build-outs in Vermont.
It would be wise to buy most of that RE from Hydro-Quebec at about 6 c/kWh under long-term contracts. H-Q could provide at least 2,000 MW to Vermont.
Vermont annual electrical consumption is estimated at about 5,554,500,000 kWh/yr. The SPEED program has a goal of 20%, or 1,110,900 MWh, of total statewide electric retail sales be generated from NEWLY-BUILT RE projects, including solar, wind, biomass, landfill gas, farm methane, and hydro plants, by end 2017.
The SPEED program has two categories of projects:
- 2.2 MW or less, Standard Offer: capped at 127.5 MW, feed-in tariffs set by the PSB.
- Greater than 2.2 MW; no cap, owners sell to utilities under PPAs at about 10 c/kWh, or 2 times NE grid prices.
SPEED Projects 2.2 MW or less, Standard Offer
The SPEED program, with help of subsidies from the Clean Energy Development Fund, produces expensive energy. Adding more money to the CEDF would worsen a bad situation.
To facilitate chasing subsidies, the CEDF and SPEED program were created by RE promoters, some of whom decided to resign from the CEDF board, because of conflict of interest, as they owned RE businesses that built CEDF-subsidized and SPEED-subsidized projects.
Here are the production results for the SPEED Program, 2.2 MW or less:
Year..........Production.........Cost..........$/kWh.....% VT Use
2013.....44,822,813.......8,692,749.09.....0.1919........0.81; a real barn burner!
The above “Cost” column shows the amount paid mostly to the risk-free tax shelters of in-state and out-of-state multi-millionaires, who own the larger PV solar systems.
Based on an solar-energy-weighted annual average wholesale price of $0.065/kWh, during the ISO-NE defined "Peak-Period", at which GMP, et al, could have bought the energy, the excess payments were:
These excess payments were rolled into the electric rates of already-struggling households and businesses. These payments will increase to about $62.5 million by 2017, because the PV solar feed-in tariff, set by the PSB, is an excessively high 25.7 c/kWh (based on “avoided cost-based prices”), and because of VT’s unrealistic SPEED goals. See notes. Other feed-in tariffs are:
PV Solar...........................0.257 (cap)
Wind over 100 kW...............0.118
Wind 100 kW or less.............0.253
NOTE: Vermont’s SPEED goal: 20% of total statewide electric retail sales during year commencing January 1, 2017 must be generated by SPEED resources that constitute NEW renewable energy, or 0.20 x 5,554,500,000 kWh/yr (assumed VT consumption in 2017) = 1,110,900,000 kWh/yr, with:
- SPEED projects greater than 2.2 MW (no cap) producing 777,630,000 kWh/yr (assumed at 70%), and
- SPEED projects 2.2 MW or less (capped at 127.5 MW) producing 333,270,000 kWh/yr (assumed at 30%).
Note the RISING $/kWh trend, whereas RE promoters were claiming RE rates would decline.
Such high RE energy costs will increase Vermont household electric rates, which already are the 4th highest in the US, right after Connecticut, Alaska, and Hawaii.
Solar SPEED is compensated at an outrageously high 25.7 c/kWh for ALL energy fed into the grid, and non-SPEED, mostly roof-mounted solar systems, is compensated at the electric rate + 6 c/kWh, for all energy produced, in the GMP North service area. In the GMP South service area different, less generous, rules apply.
NOTE: The SPEED value of 25.7 c/kWh is at least 10.2 c/kWh too high. According to David Hallquist, CEO of VEC, it should be 15.3 c/kWh for systems 1,000 kW and up. That value is of great benefit for the risk-free tax shelters of multi-millionaires, but excessively increases the electric rates of already-struggling households and businesses.
The only reason for such a high feed-in tariff is to attract investors, build many projects, and then crow about the "success" of the SPEED program. How much the additional burden will be on already-struggling households and business is carefully finessed with glowing PR releases.
EXAMPLE OF SOLAR ENERGY-WEIGHTED, ANNUAL AVERAGE WHOLESALE PRICE
Solar energy occurs during the ISO-NE defined "On-Peak" period of 7 AM - 11 PM. The cost of energy of any large SPEED solar facilty up to 2.2 MW, connected via a substation, to Vermont's high voltage grid, should be compared against the solar-energy, weighted-average, wholesale price, as follows:
1) Determine the local irradiance, kWh/m2/d, for 12 months. See URL.
2) Monthly irradiance x the days of each month = monthly solar energy production, kWh. The annual solar energy production is 1,265 kWh per kW of panels. That is for NEW, CLEAN panels, snow/ice-free, facing solar south, at the proper fixed angle. Most owners get less.
3) Monthly wholesale rate, $/kWh x monthly solar energy production = monthly solar energy value, $/mo. The annual solar energy value $88.36
Open July 8, 2014, “Monthly Data by Load Zone” spreadsheet, go to bottom of page, click on VT tab, monthly wholesale prices, $/kWh, appear.
4) Divide ($88.36/yr)/(1265 kWh/yr) = $0.0698/kWh. This is the solar energy-weighted, annual-average wholesale price. This value is high, because of the winter gas shortage; a more likely value would be about $0.065/kWh.
PV solar is disruptive, variable, intermittent energy, that requires special coddling and balancing for accommodating it to the grid, as Germany has found out in the Bavaria, etc. Therefore, it is worth LESS than $0.065 cents/kWh.
EXAMPLE OF PV SOLAR INEQUITY IN SPRINGFIELD, VERMONT
The 5 x 500 kW PV Solar Tax Shelter in Springfield, VT, estimated cost is $8 million, or $3,200/kW.
The state will pay to the risk-free, tax shelters of in-state and out-of-state multi-millionaires, who typically own such systems 2,500 kW x 8,760 hr/yr x capacity factor 0.143 x 25.7 c/kWh = $804,847/yr for 25 years, for a total of $20,121,173; Yikes!!
According to Hallquist, the feed-in tariff should be at most 15.3 c/kWh, but the PSB has hired a consultant, who appears to live on another planet, and came up with 25.7 c/kWh; it was 27 c/kWh!!!
The PSB happily accepted that, to make at least the PV solar part of the SPEED program a "success", now that the destructive experiment of wind turbines on ridgelines has come to a dead end, as it has proven to be an expensive fiasco.
Remember, the Springfield investment is only $8 million, but about 30% of it will be a gift from the federal government, with the difference likely borrowed at low rates, , because of low risk, and the whole project being written off in about 5 years to reduce federal taxes. Is that a lucrative gravy train or not?
GMP could have bought that energy for about 6.5 c/kWh, at least for the first few years, because grid prices likely will be steady during those years. After that, grid prices may rise at about 2 percent per year with inflation.
What happens to the cost difference? Oh, that gets charged to already-struggling households and businesses.
Vermont households already are "enjoying" the 4th highest household electric rates in the US, plus, are having a cost of living index 20% greater than the US average.
For Vermont, increased energy efficiency would be so much less costly and more effective than building out SPEED. It would actually REDUCE the energy costs of already-struggling households and businesses:
- Trying to make ends meet/hold their own, most of them with declining or stagnant real household incomes since about 2000,
- In a near-zero-growth Vermont economy,
- With a cost of living index 20% greater than the US COL,
- With a government plus quasi-government sector growing at a greater rate than the increasingly-hollowed-out private sector, and
- With the fourth highest electric rates in the US, right after Hawaii, Alaska, and Connecticut, partially due to having to subsidize and finance expensive, ineffective wind energy and solar energy SPEED programs that produce disruptive, variable, intermittent, i.e., junk energy, at 3-4 times NE grid prices. See URLs.
EXAMPLE OF WIND AND SOLAR ENERGY “CONTRIBUTING” DURING WINTER PEAK DEMANDS
New England installed wind turbines at end 2013: 119 VT + 171 NH + 431 ME + 103 MA + 9 RI + 0 CT = 833 MW, at a cost of about $2.5 billion, including grid build-outs
During a winter peak period, per ISO-NE, RE was 5% of 24,294 MW demand = 1,214.7 MW, of which wind was 17%, or 206.5 MW.
Thus, at that time, the CAPACITY FACTOR for all of New England was 206.5/833 = 0.248, which is in accordance with the NE ANNUAL AVERAGE capacity factor of 0.25, as published by the US- DOE, which means it was an average windy day.
New England installed PV panels at end 2013: 36.13 VT + 8.22 NH + 8.12 ME + 361.55 MA + 10.9 RI + 73.75 CT = 498.7 MW ac, or 607.4 MW dc.
NOTE: ISO-NE measures MW in ac.
During the SAME winter peak period, per ISO-NE, grid-connected PV solar was 1% of RE = 12.147 MW ac, or 14.8 MW dc.
Thus, at that time, the CAPACITY FACTOR for all of New England was 14.8/607.4 = 0.024, which means that period was cloudy, and the panels were producing at 0.024/0.14 = 17% of the ANNUAL AVERAGE capacity factor of about 0.14
Variable, intermittent wind and solar energy are expensive feel-good contributors, "there" on a sporadic basis, cannot be relied on, unless utility-scale energy storage is invented and deployed, which will take many billions of dollars and decades, just in New England.
SPEED Projects greater than 2.2 MW
The following wind turbine plants in the "greater than 2.2 MW" category, with their estimated annual energy production and capacity factors, are listed on the DPS website:
Granite Reliable ..........215,496 MWh, Coos County, NH. GMP contracted to buy 55% of the output for 20 years starting April 1, 2012.
Sheffield.......................103,372 MWh.........CF 0.295
Lowell..........................182,909 MWh..........CF 0.331
Georgia.........................27,000 MWh..........CF 0.308
Burlington Electric Department 2012 power supply:
Georgia: BED contracted for 10 MW of 10 MW, and bought 76.2 MWh; partial year operation.
Sheffield: BED contracted for 16 MW of 40 MW, and bought 32,339 MWh; full year operation.
Sheffield 2012 production: 40/16 x 32,339 = 80,847.5 MWh, for a CF = 80,847.5 MWh/yr/(8,760 hr/yr x 40 MW) = 0.2307.
Here are the 2013 expected ridgeline wind production results:
Sheffield….. 40 MW......$120 million.........…83,395 MWh...........CF 0.238
Lowell*…. …63 MW......$170 million.........113,687 MWh...........CF 0.206
Georgia…....10 MW........$28 million..........21,024 MWh............CF 0.240 Est.
Total........113 MW.......$318 million.........218,106 MWh
*Includes grid and substation upgrades and $10.5 million synchronous-converter system mandated by ISO-NE.
Note the much lesser ACTUAL production, MWh and CFs, versus the optimistic values indicated on the DPS website.
Wind turbines on ridge lines in New England are a fiasco. No wind turbines can be constructed in the NEK, until at least $200 million of grid upgrades are made, which will not happen for about 10 years, per Vermont Rep. Klein. The 60 MW Seneca wind turbine project was cancelled because $86 million of grid upgrades were needed!!
1) Lowell Mountain, capacity 63 MW, capital cost about $170 million, 11-month production = 104,213 MWh in 2013; CF = 0.206, which will not become much greater with the ISO-NE mandated $10.5 million synchronous converter system, which was supposed to be on line in December 2013, but is still not on line. There appears to be a blackout of information.
Estimated heavily-subsidized energy production cost of 15 - 20 c/kWh, based on:
- 20-yr life, due to harsh conditions,
- Low ridgeline CF, due to inadequate, low quality wind,
- High ridgeline O&M cost/MWh,
- High ridgeline capital cost/MW, and
- Much less revenues from Renewable Energy Certificates due to less energy production.
GMP estimated production 63 x 8760 x 0.2842 = 156,844 MWh/yr, with standard rotor.
GMP estimated production 63 x 8760 x 0.3587 = 197,959 MWh/yr, with 373 ft rotor.
GMP estimated production 63 x 8760 x 0.3380 = 186,570 MWh/yr, per GMP website.
Actual production in 2013: 63 x 8760 x 0.206 = 113,687 MWh.
NOTE: Green Mountain Power testified to the PSB, the CF would be 0.3587, “with the bigger rotor”. See URL
Already-struggling Vermont businesses and households in GMP’s service area, about 70% of Vermont ratepayers, will be on the hook for the extra Lowell costs for 20 or more years. GMP will not suffer, because it will roll all its extra costs into rate schedules, per PSB approvals.
2) Sheffield Mountain, capacity 40 MW, capital cost about $120 million, 11-month production = 76,329 MWh in 2013; CF = 0.238; better than Lowell, but much less than the predicted 0.33 or better.
3) Georgia Mountain, capacity 10 MW, capital cost about $28 million, 11-month production in 2013 likely was similar to Lowell and Sheffield.
SOLAR AND WIND ENERGY, percent of total consumption
Solar: Total energy from solar from about 44 MW of panels, SPEED and non-SPEED, in 2013, was about 44* MW x 8,760 hr/yr x capacity factor 0.14 = 53,962 MWh.
* Vermont had installed about 28 MW at end 2013 and about 44 MW at end 2013. ISO-NE adjusted this DC value to 36.13 MW, AC basis, the same basis as traditional AC generators.
Vermont consumption is about 5,600,000 MWh/yr, of which about 53,962/5,600,000/100 = 0.96% from solar, mostly SPEED solar.
Capital cost, nominal dollars, was about 44 MW x 5.0 million/MW (3.5-yr average SYSTEM price) = $220 million over the past 3.5 years.
Wind: Total energy from wind, in 2013, was about 218,106 MWh.
Vermont consumption is about 5,600,000,000 MWh/yr, of which about 218,106/5,600,000/100 = 3.89% from wind.
VERMONT'S WIND ENERGY SCAM
Vermonters are the victims of a grand, fraudulent charade to promote heavily subsidized, expensive wind energy on ridgelines, primarily to schlep as much federal subsidies to Vermont as possible, mostly for the benefit of the well-connected, multi-millionaires with tax-shelters.
Reports were written about the abundance of wind on ridgelines, and it being a great renewable energy source for Vermont, and leading to energy independence, and creating jobs. No more reliance on those dirty fossil fuels and that dangerous Vermont Yankee.
The CEA report was written for Vermont utilities to guide them towards renewables. CEA based its analyses on CFs = 0.33, quoting "Vermont sources". Page 23.
After the CEA report was issued, Blittersdorf, a self-proclaimed Vermont wind guru, owner of 10 MW Georgia Mountain, helped James Moore write the VPIRG "Repowering Vermont" report, which used wind turbine capacity factors of 0.33, quoting the CEA report, which quoted "Vermont sources". Yikes!
And Vermont legislators were fed this garbage, wanted/pretended to believe it, as it provided a fig leaf for CYA purposes, and enacted laws accordingly, even though evidence of poor CFs of Northeast wind turbine plants, about 0.245, already existed in US and Maine government reports, and were known to the Legislature, DPS and PSB, because they were informed of their existence by several Vermont sources, including myself.
MISCARRIAGES AND BIRTH DEFECTS DUE TO WIND TURBINES IN DENMARK
Below is an article, which details the impact on newborns when wind turbines are placed too close to people and animals. The article is food for thought/introspection for Shumlin, Klein and other wind turbine aficionados.
Wind turbines adversely impact the fetuses of pregnant women and other fauna species susceptible to low frequency vibrations from wind turbines, a.k.a. infrasound with frequencies less than 20 Hz. Infrasound cannot be heard, but is felt. Infrasound travels much longer distances than audible sounds that have higher frequencies.
The PSB, so-called "Protector of the Public Interest", refuses to:
- Admit adverse health effects exist, despite numerous reports to the contrary
- Measure and regulate infrasound, despite numerous complaints from nearby people
- Regulate and enforce minimal setback requirements of about 2 km from a residence.
Excerpt from the article:
“Politicians, and wind industry shills who … deny the risks to health, are now liable to be successfully sued by wind farm victims. And so are governments, as they still refuse to measure infrasound emitted by modern wind turbines.”
In Denmark last month, 1,600 animals were born prematurely at a mink farm. Many had deformities, and most were dead on arrival. The lack of eyeballs was the most common malformation. Veterinarians ruled out food and viruses as possible causes. The only thing different at the farm since last year has been the installation of four large wind turbines at a distance of 328 meters, or about 1,000 ft. The wind farm consists of four 3 MW turbines, VESTAS model V112, reaching out to 140 meters in height at the tip of the blades. When they became operational last fall, a first mishap was reported by the mink farmer at a parliamentary committee on wind farms in January this year.
NOTE: The 3 MW turbines are exactly the same as at LOWELL MOUNTAIN!!!
The Green Mountain Power, 63 MW Lowell Mountain wind turbine facility with (21) 3 MW Danish, Vestas V-112 wind turbines, 367.5-ft (112 m) rotor diameter, 275.6-ft (84 m) hub height, total height (275.6 + 367.5/2) = 459.3 ft, stretched along about 3.5 miles on 2,600 ft high ridge lines, has nothing to do with community-scale wind, everything with industrial, utility-scale wind. The housings, 13 ft x 13 ft x 47 ft (3.9 m x 3.9 m x 14 m), on top of the 280-ft towers, are much larger than a Greyhound bus.
REGIONAL WIND TURBINE CAPACITY FACTORS
Wind energy promoters have testified before the PSB that their ridgeline wind turbine plants will have CFs of about 0.33 or better. Actual production results in Maine, New York, indeed all of the Northeast, have shown their testimony as not valid.
New York State: Here are the actual capacity factors of New York State. They are not anywhere near project-owner claimed values of 0.33, or better, to get permits and subsidies from gullible/complicit government entities
US Regions: Here are the official regional 2012 CFs for NEW projects commissioned in 2010 and 2011:
See page 48 of URL.
Maine has a CF of 0.25
Wind Energy Production and Capacity Factors, by State
The below table lists the wind energy production and capacity factors for Vermont for the past 3 years. The data, FOR EACH STATE, are from the Energy Information Administration, EIA, a part of the US DOE.
In 2013. Vermont had the fifth lowest CF, after Utah, Tennessee, Nevada, Arizona.
* Lowell, 63, Sheffield 40, Searsburg 6, for a total of 109 MW. Georgia Mountain, 10 MW, is not reporting to the FERC, and its production, MWh, is excluded.
HIGH RENEWABLE ENERGY COSTS DAMAGE GERMANY'S ECONOMY AS WELL.
A Lesson for Vermont: It is clear from the German RE "leadership" example, Vermont’s 2011 CEP goal of 90% of ALL energy from RE by 2050 (not just electrical energy which is only about 1/3 of ALL energy), whereas a technical possibility, would not be economically tenable, even if other New England states had similar ambitions to handicap their economies, businesses and households.
Vermont’s cost of living index would become so high, many people would vote with their feet, after having been unable to make Montpelier mend its ways.
BTW, poor Vermont's 90% goal is much more ambitious (starry-eyed, irrational?) than rich Germany's goals.
