Arlington Energy, a clean energy investment group, has announced plans to build out a 1GW portfolio of energy storage and gas peaker projects across the UK after securing initial funding of £200 million (US$255 million) from an offshore fund of institutional investment.

The UK’s transmission system operator National Grid’s redesigned Capacity Market targets around 50GW of reserves up to 2023 and could be an early step towards longer duration energy storage batteries.

After reporting last week on the findings from EMMES, the European Market Monitor on Energy Storage from Delta-ee and trade association EASE, which demonstrated a big rise in installations by MWh in 2017 across the continent, we delved further behind another record-breaking year with the report’s lead author, Valts Grintals of Delta-ee.

Cleve Hill Solar Park, the joint venture (JV) of Hive Energy and Wirsol intending to develop a 350MW+ solar farm on the Kent coast of England, has yet to make any decisions regarding the battery storage element of its plans, contrary to media reports.

Fluence says it has secured the single largest energy storage portfolio transaction for a technology provider announced in the UK to date after being selected by UK Power Reserve (UKPR) to deliver half of its battery storage portfolio.

The “devil is in the detail” when it comes to making regulatory changes in the US to open up wholesale markets for energy storage to participate in, a regional chief of regulator FERC has said.

The capacity market is rapidly becoming “outdated” after the latest auction failed to secure capacity and value for new technologies like energy storage, which is now in “a state of flux” following changes to de-rating factors.
