Engie’s Daronnat: pricing flexibility in the German battery market
Head of flexibility and structured origination discusses the role of FPAs and what risk teams must consider
Germany’s legally binding target to have 80% of electricity coming from renewable energy sources by 2030 requires the country’s renewable energy capacity to reach around 300 gigawatts (GW). To keep supply and demand balanced amid this level of intermittent production will require substantial growth in the battery energy storage systems (Bess) market, say analysts.
Engie has big ambitions for participation in this market, aiming to have 10GW of installed battery capacity globally by 2030, up from the current capacity of around 3GW. The firm’s origination work around its battery portfolio includes optimising its own assets and operating batteries for clients.
In this video, Martin Daronnat, head of flexibility and structured origination in Germany at Engie International Supply & Energy Management, discusses the booming German battery market and the different options available for bringing battery projects to market.
He explains the vital role of flexibility purchase agreements (FPAs), the different types available and the structuring and risk management expertise they require.
