How should developers and investors think about long-term BESS revenues in light of eventual market saturation?

Power firm EnBW is building a 100MWh BESS in Germany for completion this year (a year later than planned) while BESS platform Noveria Energy has signed a construction agreement with TSO TenneT for a 1GWh project for 2028 operations.

BESS platform Ingrid Capacity has received construction permits for two projects in Sweden’s SE4 electricity region which it said could start construction as early as this year.

Building BESS is complicated, with myriad considerations around supplier contracts, site acceptance tests, data analysis, interface between different contractors.

The attractiveness of the BESS market for M&A and investment, amidst a slowdown in activity, was discussed on a panel at the Energy Storage Summit 2026 in London.

How can the industry prepare for when the first wave of utility-scale BESS projects begin to reach end-of-life?

Over 1.4GW/3.4GWh of grid-scale BESS came online in Europe, likely its best month ever, accounting for almost a fifth of global figures.

NGEN and Harmony Energy have made strides in deploying large-scale BESS projects in Germany, launching construction and securing pipeline financing respectively.

We catch up with Tamara de Gruyter, president of Wärtsilä Energy Storage, to discuss the system integrator’s strategy under new leadership.

Dutch TSO TenneT has signed a contract with a developer for a large-scale BESS which will help to relieve grid congestion, possibly enabling the quicker deployment of renewables in the Netherlands.
