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?

August 14, 2014 by Sarah Battaglia

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]

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]

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]

Hawaii and Energy

From an energy perspective, Hawaii is unique. Located in the middle of the Pacific, the Aloha State runs on imported oil. But its island environment—from sunny days to active volcanoes—also holds the keys to a future powered by renewable energy.[read more]

Hawaii's Solar-Grid Landscape and the 'Nessie Curve'

Hawaii and the Solar Grid

If California grid planners are worried about the famous “Duck Curve,” which is used to represent the future disruptions that distributed solar PV systems will have on the state’s grid, they should do themselves a favor and check out Hawaii’s “Nessie Curve.”[read more]

Will Solar Energy in Hawaii Be a Test Case for High Grid Penetration?

Solar in Hawaii

Hawaiian Electric Companies issued a press release titled “Rooftop PV enjoys another strong year in Hawaii.” The release started out sounding as celebratory as its title suggested, proclaiming the “rapid growth in rooftop solar” in the state, but it finished by warning of the dangers to the grid of so much solar.[read more]

The US NOAA has updated its CO2 graphics, via its Trends in Carbon Dioxide page:         And for those wanting the Big Picture:     Maybe I’ve been paying too much attention to the deniers lately, but I can’t quite discern a pattern in any of these. Can someone here toss me a hint? In any case, if you...[read more]

Hawaii’s New Feed-In-Tariff For Solar PV Not Having Big Impact Yet

January 11, 2011 by Reginald Norris

Recently, Hawaii adopted a feed-in-tariff to support the adoption of solar power in Hawaii. Already a leader in solar thermal, Hawaii is on the progressive edge in the U.S. with the adoption of its program. As a refresher, a feed-in-tarrif is essentially where your utility company has to pay you cash for the amount of energy your solar...[read more]

Don't Weep for the Trees

October 22, 2009 by Robert Rapier

While I have no intention of changing the general theme of this blog, I will spend some essays in the future providing more details behind my new job in Hawaii. I did this on occasion with my previous job at Accsys, but the focus of the blog remained on energy, sustainability, and the environment.As explained in the previous essay, my...[read more]
