Nonprofit utility Platte River Power Authority has issued a request for proposals (RfP) for at least 20MW of solar PV systems and up to 5MWh of battery energy storage for its power mix in Colorado.

RES (Renewable Energy Systems) has confirmed the expected capacity and output of a photovoltaics-linked energy storage system being developed for a railway in Canada which will use lithium-ion batteries.

Germany’s sonnen introduced a scheme a while back in which customers pay a flat, reduced rate for their electricity each month while the company aggregate their batteries together to benefit the grid – and now the offer has been extended to electric vehicle owners.

AES Distributed Energy (AES DE), a subsidiary of AES Corporation, and nonprofit transmission firm Kauai Island Utility Cooperative (KIUC) have broken ground on a 28MW solar and 100MWh five-hour duration battery energy storage system in Kauai, Hawaii.

The government of Jordan has given parties interested in delivering a 30MW energy storage system in the Kingdom six months to come up with technical and financial offers.

Microgrids ensure energy security for mission-critical loads at military bases, and reduce reliance on fuel during grid outages. While they have much in common with many of the technologies used in ‘other’ microgrids, the stringent technical requirements involved add a new layer of complexity, explain Lisa Laughner and Tony Soverns from provider Go Electric.

The first large-scale solar and battery storage project to be connected to the grid in Australia has started providing power to 3,000 homes and businesses in Far North Queensland (FNQ) while forming a test case for deliberate ‘islanding’.

The winner of India’s first major solar-plus-storage auction, which has subsequently been scrapped for retendering, has said that despite being an unfortunate development, the firm is still keen to work closely with government on this technology for which the economics are continuously and rapidly improving.

A US government energy saving scheme will pay out US$40 million for the development of a solar-plus-storage microgrid at a missile test site operated by the country’s military.

Utility Florida Power & Light claims that a just-completed battery addition will increase output from a large-scale solar farm in its home state, thought to be the first time a DC-coupled solution has been used at this scale in the US.
