It comes three months after Kyon announced a 600MW pipeline of BESS projects with renewable energy developer and financing firm Obton, while the pair collaborated on a 32MWh system commissioned last year, which Kyon developed and Obton financed. Kyon didn’t specify whether the new project is part of that co-operation.

Deployments in the German grid-scale energy storage market have picked up sharply since 2022 after the quiet few years which followed the saturation of available ancillary service market opportunities. Alongside increased opportunities in ancillary services and energy trading, federal grants for co-located projects are helping drive growth in projects under Germany’s Innovation Tender.

Some 400MW of solar-plus-storage projects recently won Innovation Tender contracts which will give them an additional premium per kWh of energy discharged.

Kyon said the new project will provide grid stabilising services as well as helping to integrate more renewables onto the grid, with its 2-hour duration allowing for more energy-intensive activities.

As Energy-Storage.news reported last month, 2-hour BESS projects in Germany are now deriving a majority of their revenues from energy-driven activities like wholesale energy trading and the provision of energy through ancillary service aFRR (automatic frequency restoration reserve).

One-hour systems meanwhile still make most revenues through FCR (frequency containment reserve, which requires a response time of 30 seconds versus five minutes for aFRR), and having capacity available for aFRR, which is remunerated separately to actual provision of energy.
