Following news yesterday of the first grid-scale solar-plus-storage system on the Hawaiian island of Molokai, two more modestly-sized projects show the potential diversity of applications for energy storage in the US state.
Minnesota electric cooperative Connexus Energy has confirmed recent press reports that it is building 15MW / 30MWh of battery energy storage, while another not-for-profit, Vermont Electric Cooperative, will build a 1.9MW / 5.3MWh system in its service area.
In response to Massachusetts Legislature passing a bill raising the state’s renewable energy standard and another encouraging clean energy and energy storage use during peak hours, solar and energy storage trade groups SEIA and ESA offered contrasting views.
Vistra Energy has contracted energy storage integrator FlexGen to install a 10MW / 42MWh energy storage system (ESS) at the 180MW Upton 2 Solar Power Plant in Texas.
The residential energy storage market in the US has just enjoyed one of its biggest growth spurts so far, although action is mostly centred in specific states with supportive policies and conditions.
Solar industry veteran and PV Tech blogger Edgar A. Gunther was told by the New Jersey Governor Phil Murphy’s office that clean energy legislation proposed for the state is “on his desk” but appear to be no closer to receiving his approval.
NextEra Energy Resources and utility Salt River Project (SRP) have completed the Pinal Central Solar Energy Center in Arizona, an integrated PV plant equipped with a battery system that will store energy and allow SRP to provide power to its customers.
Hawaii’s position as one of the leading US states for energy storage deployment shows no sign of weakening as Hawaiian Electric Co last week announced 120MW of new battery storage across two projects in Oahu.
The US government Department of Energy is funding research into storing energy for periods of between 10 and 100 hours, announcing last week that “up to US$30 million” will be available through the Advanced Research Projects Agency-Energy (ARPA-E).
