A Hawaiian macadamia nut farm gets solar and storage, achieving 100% renewable power

 Hawaii-based Mauna Loa, one of the world’s major macadamia nut brands, just got a 1.2-megawatt solar farm and 500 kW battery storage system. The new solar and storage join existing clean energy sources at the facility, which means it’s now powered by 100% clean energy.

Solar installer SolarCity announced this week a new package combining solar panels, battery storage, smart electric water heaters and the Nest Learning Thermostat in order to “prevent energy from being exported back to the grid”, says the company in a new press release.

The system, called ‘Smart Energy Home’, will first be offered in Hawaii, where the company had problems with the local electric utilities before.

SolarCity announces that it will use Tesla Energy’s Powerpack for its massive 52 MWh project in Hawaii

Last week we reported that SolarCity more than doubled its battery pack business with Tesla Energy in 2015 versus the previous year, and the trend is set to continue as the solar installer confirmed today that it selected Tesla’s energy division to supply its massive energy storage project on Kaua’i Island in Hawaii.

We reported on the project last year when SolarCity announced its power purchase agreement (PPA) with Kaua’i electric utility (KIUC) for two 12 MW solar arrays and their intention to install 52 MWh of energy storage.

SolarCity signed a 52 MWh solar energy storage deal to power Kaua’i with solar energy when the sun is down

f81d49ad9dcea625600f6a706700d751SolarCity announced today that the company signed a power purchase agreement (PPA) with Kaua’i electric utility (KIUC). SolarCity already built a 12-megawatt solar array for KUIC which  went into operation in September 2014 and now supplies 5% of the island’s electricity, but under the new deal, the California-based solar installer will develop a new solar array and a massive 52 MWh energy storage system to provide electricity when the sun is down.

The State of Solar in Hawaii is a look into the future

A great ground look at what’s happening in Hawaii, the state where energy costs the most and where there is plenty of solar energy.  Over 12% of Hawaiians have solar power which is 20x the US national average.  If you count all the rooftops on Oahu together, Solar is a 300MW plant that is more than double the size of the next biggest plant on the island.

The problem is: That power plant dies when the sun goes down and the other plants have to crank way back up.

Hawaii makes it law to adopt 100% renewable energy by 2045

If you are to set a goal for the production of renewable energy, why not make it 100% of total production? This is exactly what Hawaii did this week by enacting a law imposing requirements for electric utilities to supply the state with 100% renewable energy by 2045. Hawaii is already a leader in clean energy with 22% of their electricity production coming from wind, solar, geothermal, and other renewable energy resources. The new policy, Act 97, would require electric utility to produce 30% of their energy from renewable sources by the end of the decade and 100% within 30 years.
