Hawaii and Advanced Energy

Ah, Hawaii. The palm trees sway in the tropical breezes, the volcanoes cast long shadows on beautiful white sand beaches, and diesel-fired power plants generate electricity at the highest prices in the country. Big things are afoot for the electricity system of this tiny U.S. state, though.[read more]

Hawaii's Utility Is Approving a Backlog of More Than 3,000 Solar Installations

Hawaii Solar Installations

Last week, utility Hawaiian Electric (HECO) said it had approved all the delayed rooftop solar applications on Maui and Hawaii island that had been waiting since October, according to Jim Alberts, senior VP of customer service at HECO, who spoke at the Maui Energy Conference.[read more]

Friction at the Grid Edge: Hawaii's PUC Orders HECO to Approve Solar Rooftops

Hawaii and Rooftop Solar

The latest skirmish in the Hawaiian solar power struggle stems from a letter sent out last week by HECO to 50 Big Island residents that suggested that until the islands' net energy metering policy is settled, interconnection approval of new PV would be on hold, according to a report on KHON Honolulu.[read more]

Something Astounding Just Happened in the Solar Energy World

You've read the Hawaiian announcement last week about micro inverter manufacturer Enphase. It alluded to a big thing but I couldn’t quite work out what had happened so I called some friends. The reality of what these guys just did and have achieved in the real world is really quite astonishing.[read more]

Can Microinverters Stabilize Hawaii's Shaky Grid?

Hawaii Grid Stability

Hawaii leads the U.S. in rooftop solar penetration, with one in nine customers, tying their PV systems into the state’s grids. About 3/5 of those solar systems use microinverters from Enphase, who lead the market for DC-to-AC devices that sit at the solar panels themselves, rather than next to the power meter.[read more]

Charting Hawaii's Spectacular Solar Energy Growth

Hawaii Solar Growth

The U.S. Energy Information Administration (EIA) released a report on Hawaii’s solar status this week, and Hawaii is officially a solar hot spot of national significance, and that makes it a fitting test bed for Department of Energy research meant to stretch the limits of rooftop PV penetration on island grids.[read more]

Torrefaction via Radio Waves

Radio Waves and Energy

I have found over the years that the vast majority of biomass to energy projects aren’t economically viable for one reason or another. I have looked at companies that utilize many different conversion technologies, and most of the time my job consisted of searching for fatal flaws of different approaches.[read more]

Hawaii to Test Smart Water Heaters as Grid Resources

November 22, 2014 by Jeff St. John

Hawaii and Smart Water Heaters

Hawaiian Electric is trying out all sorts of distributed energy assets to help it manage its solar-impacted island electricity system, including behind-the-meter batteries, and smart-meter-enabled energy disaggregation. But one of the cheaper grid tools at its disposal could be the ubiquitous electric water heater.[read more]

As Hawaii Prepares for Utility Reform, the State's Solar Industry Sheds 3,000 Workers

September 28, 2014 by Stephen Lacey

Hawaii's solar industry is in a precarious situation. As regulators and the state's utility company prepare to negotiate a sweeping reform plan to support more distributed energy, solar installers are finding it harder than ever to get permits for residential solar projects from the utility.[read more]

Stem to Install 1MW of Networked Behind-the-Meter Batteries in Hawaii

September 20, 2014 by Jeff St. John

Hawaii Networked Batteries

Hawaii is facing some serious disruptions from its growing share of distributed rooftop solar, and it’s going to try Stem’s distributed grid energy storage as a solution. On Thursday, utility Hawaiian Electric announced it had picked the Millbrae for a 1-megawatt pilot project on the island of Oahu.[read more]

How Much Longer Until Solar Eliminates the Utilities?

If you’re thinking of packing up the kids and moving to Hawaii, you better consider this one drawback: energy is very expensive! Since Hawaii must pay to import oil to power its electric grid, customers are left paying more. Most are turning to rooftop solar as a way to alleviate the financial burden.[read more]

When the Wind Doesn't Blow

Renewables and Intermittency

The average capacity factor - the percentage of time an electricity-producing asset is actually producing maximum power - is 40% for wind power in the US. The Hawi Renewable Development Wind Farm is better, at 45 percent, but for the 55% of the time it isn’t producing power, backup is required.[read more]

I Almost Bought Hawaii's Electric Utility for $6B and Made It a Renewables Paradise

Renewables Paradise?

I have a confession to make. In 2011 I became involved, in a small way, in a multi-billion-dollar scheme to buy out HECO, Hawaii's electric utility, and take it private. The plan was to shift HECO from its reliance on fossil fuels and allow the island to be powered by its natural gifts of geothermal, solar and wind.[read more]

Hawaii Wants 200MW of Energy Storage for Solar, Wind Grid Challenges

Hawaii Electric Company launched one of the biggest energy storage proposals in the country last week, quietly opening up requests for proposals of 60 to 200 megawatts of storage project to help manage the solar and wind power that’s wreaking havoc with Oahu’s island grid.[read more]

Renewable Hydrogen on the Big Island

Renewable Hydrogen

Hawaii has abundant energy resources from wind, the sun, geothermal, water, and biomass. Yet Hawaii relies on petroleum for 80 percent of its energy, making it by far the most petroleum-dependent state. This is because Hawaii is the only state that still gets a large portion of its electricity from oil.[read more]
