The way we think about battery storage tech is evolving as quickly as the industry is, writes Dr. Matthias Simolka, product manager at battery data analytics provider TWAICE.

This Friday Briefing looks back at how the industry in 2021 theorised the UK battery storage market playing out.

The first energy storage asset built using Wärtsilä’s new Quantum High Energy battery energy storage system (BESS) solution will be a 300MW/600MWh project in Scotland, UK.

San Diego Gas & Electric (SDG&E), one of California’s main investor-owned utilities (IOUs), has brought online a portfolio of four ‘advanced’ microgrids equipped with 180MWh of battery storage.

Utah is not perhaps a US state people would immediately associate with cutting edge clean energy tech development, but that’s where sonnen’s virtual power plant (VPP) offering took shape.

This week’s Friday Briefing is largely concerned with the UK’s current period of low revenues for battery storage and how the market can move forward.

EDF Renewables UK has entered into an optimisation agreement with investors DIF and ib vogt to optimise a co-located solar and storage project in the UK.

Wärtsilä’s energy storage division saw a 20% year-on-year increase in sales and a 31% increase in order intake from 2022 to 2023, with the company board in mid-consideration of the business unit’s future.

Optimising co-located BESS is “much more complicated” than standalone and few companies can do it well, panellists on Day 2 of Solar Finance & Investment Europe (SFIE) said.

Independent power producer Low Carbon has signed optimisation agreements with Habitat Energy, Flexitricity, and EDF across four battery energy storage systems (BESS) with a capacity of 95MW.
