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.
