In the latest edition of downstream solar PV technology journal PV Tech Power, writers from Energy-Storage.News and PV Tech have profiled 10 of the top system integrators working in grid-scale energy storage today.

An ambitious project to convert the “grey fleet” of a care home for old folk in Scotland to a sustainable “green fleet”, using solar PV and battery energy storage, was winner of the Residential, Commercial and Industrial-scale Storage Project category at this month’s Solar Power Portal Awards.

Kiwi Power is to finance and develop a battery storage project at a multi-technology renewable energy site in south Wales, where it will provide constant grid services availability to National Grid for two years in a first for the aggregator.

Energy storage will increasingly be deployed to save money on electricity transmission and distribution (T&D) infrastructure, with nearly half of the global market to be found in the Asia-Pacific region by 2026, Navigant Research has said.

Car manufacturer Renault has created a new energy subsidiary which will create smart charging networks, explore vehicle-to-grid (V2G) solutions and utilise second-life EV batteries for stationary energy storage projects.

A new redox flow battery demonstration project was launched in Belfast, Northern Ireland, this week.

E.On has become the first company to have secured an Enhanced Frequency Response (EFR) contract in Britain last year to announce the completion of its project, following the installation and connection of a 10MW battery at a biomass plant last month.

Both energy storage asset owners and companies setting up to provide operations and maintenance (O&M) services for battery installations need to commit to higher levels of due diligence when selecting contractors according to RES Group’s head of solar and O&M.

UK electrical distribution system operator Northern Powergrid has begun using a £4 million (US$5.27 million) battery paid for by consumers to sell services to National Grid, despite plans from the national regulator Ofgem to prevent distribution network operators (DNOs) from doing so in future.
