Building on a proven, independent methodology developed by Clean Horizon, and Nord Pool’s long-standing expertise in delivering efficient, secure and transparent markets and market data, the partnership will introduce Clean Horizon Storage Index for three durations (1-hour, 2-hour and 4-hour). This index will be delivered by Nord Pool across all bidding zones in 15 European countries.
Participants across the BESS value chain – including asset owners and operators, market access providers, aggregators and traders – will gain access to three practical tools in one: a reliable reference for market-access contracts, a performance benchmark for trading activities, and an index that can be used as the basis for hedging through swaps and forwards.
Tom Darell, CEO of Nord Pool, commented: “This partnership with Clean Horizon reflects our commitment to supporting transparency in the green transition and delivering value to our customers. By working together, we will help de-risking the BESS industry at a time of increasing renewable penetration and more volatile market conditions.”
Michael Salomon, CEO of Clean Horizon, added: “By bringing a Europe-wide harmonised benchmarking of BESS profitability, the best athletes in industry are delivering key value to investors and the market in a predictable, consistent and transparent fashion.”
