Hawaii has been a prolific installer of both rooftop solar and latterly batteries for energy storage and one of the US state’s smaller islands looks set to get its first ever grid-scale solar-plus-storage system.
Islands around the world provide ideal conditions for trialling new approaches to energy provision. David Pratt reports on some of the work going on globally to bring the benefits of cutting-edge renewable energy, storage and smart grid technologies to the world’s geographically isolated communities. To be continued later this week on Energy-Storage.news.
Hawaii’s KIUC, the top-ranked US utility in 2017 for energy storage deployment per customer by SEPA (Smart Electric Power Alliance), will pay less than US$0.11 per kWh for power from a new solar-plus-storage facility.
Utility NV Energy has awarded contracts in the US state of Nevada for over 1,000MW of renewable energy projects – including a 420MW-dc solar farm – and has also requested approval for 100MW of energy storage.
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.
Cypress Creek Renewables, which developed 1GW of PV projects in an 18-month stretch up to the beginning of this year, has used Lockheed Martin’s lithium-ion battery storage solutions in a dozen just-completed solar-plus-storage projects.
News in brief from around the world of energy storage.
Vertically-integrated solar energy company First Solar will be involved in the first megawatt-scale battery system announced in Arizona since it was revealed the state could put a 3,000MW energy storage deployment target in place.
A large-scale solar-plus-storage project on the Hawaiian island of Kaua’i will be built using SunPower’s scalable Oasis Power Plant platform after the PV technology provider was chosen by AES Distributed Energy.
In its home territory of Germany, energy storage provider Sonnen is making a play to replace utilities, but its business models in the US will instead emphasise cooperation with existing energy suppliers.
Interest in energy storage in the Middle East is ‘ramping up significantly’, as we reported last week in an extract from this interview with IHS Markit analyst Julian Jansen. His firm is forecasting 1.8GW of energy storage for the region by 2025 – from an installed base of next-to-nothing today. Jansen talked us through some of the drivers, market dynamics and the general picture of what we might see developing.
In a major energy strategy upheaval, the South Australian government is providing significant funding to support energy storage projects, starting with a 100MW grid-connected battery that will be the largest in the country.
The US Navy plans to develop a utility-scale solar farm and energy storage system on the 863.6 hectare Pacific Missile Range Facility on the island of Kauai, Hawaii, according to a draft environmental assessment.
Solar PV paired with energy storage at scale could be provided to utilities at just US$0.10 per kilowatt hour, using advanced battery technology, one manufacturer has claimed.
The latest step in Hawaii’s clean energy evolution will be the deployment of a 20MW, five-hour duration battery energy storage system paired with 28MW of solar in Kaua’i, to match peak demand with generation.
The output of a 16MW solar farm in Puerto Rico will be tied to an Aquion ‘saltwater’ battery, in one of the few current trials of moving solar power produced in the daytime to be used at night.
SolarCity has chosen Tesla to supply a 52MWh utility-scale energy storage system, which will make the output of a solar farm in Hawaii dispatchable.
