Case StudiesReferences & Success Stories
Clean Horizon and Nord Pool launch a new distribution initiative for the Clean Horizon Storage Index
Clean Horizon partnered with Nord Pool to distribute the Clean Horizon Storage Index, a set of neutral benchmarks tracking battery storage revenues across 15 European countries. The indices provide transparency and standardisation for the European battery storage market, serving as a benchmark for storage performance, market access contracts, and potentially hedging instruments. This initiative leverages Clean Horizon’s expertise and Nord Pool’s data distribution to enhance market intelligence.
Clean Horizon supports first bank-financed energy storage project in the Baltics
Clean Horizon provided market advisory, price forecasting, and economic modelling for the first bank-financed energy storage project in Estonia and the Baltics, developed by CORSICA SOLE, Evecon, and Mirova. The Hertz 1 and Hertz 2 projects, totalling 200 MW / 400 MWh, secured €85.6 million in financing from EBRD, Nordic Investment Bank, and Edmond de Rothschild Asset Management. Once operational, this complex will be one of continental Europe’s largest, significantly enhancing grid stability.
Clean Horizon supports Kallista Energy on Saleux BESS project
Clean Horizon acted as Technical Advisor to Kallista Energy for the development of the Saleux Battery Energy Storage System in France, a 120 MW / 240 MWh project. The project, one of the largest in the country, was financed with support from Landesbank Saar and BNP Paribas, with ENGIE optimising the batteries and Envision Energy handling construction. This marks Kallista Energy’s first large-scale storage site, demonstrating Clean Horizon’s expertise in guiding projects through structuring and alignment with grid requirements.
Free webinar: 50 MW co-located BESS case study and market trends in the Nordics
Clean Horizon presented a case study of a 50 MW co-located battery energy storage system in the Nordics in a webinar with Nord Pool. The session analysed market dynamics, return metrics, and the financial viability of utility-scale storage in an increasingly volatile Nordic power market. This case highlighted the growing role of battery storage in the region’s energy landscape.
