Summary

In this keynote from the Energy Storage Summit London (February 2026), Ed Porter of Modo Energy provides a global overview of battery energy storage system (BESS) markets. He discusses the rapid growth of battery deployments and the consequent saturation of ancillary service markets, leading to a shift towards energy trading and other value streams. He highlights the importance of demand growth as a key driver for battery revenues, using examples from GB, Texas, and California. The presentation covers the solar capture rate collapse in Spain and the commercial necessity of co-locating solar with storage. Porter introduces five additional value streams for batteries: voltage control, grid rates, carbon certification, route-to-market structures (optimisers, floors, insurance), and inertia markets. He also showcases Modo Energy’s FCA-authorised indices, which enable fixed-for-variable hedging structures for asset owners. The talk concludes with the idea that the industry is still learning how to maximize the value of storage fleets.

Critical Evaluation

Value of the Information & Strength of the Argument

The video provides valuable insights into the current state and future trends of battery storage markets. It offers a data-driven perspective on market saturation, revenue compression, and emerging value streams. The argumentation is solid, supported by charts and examples from multiple regions. The presenter effectively explains complex concepts such as the duck curve, capture rates, and inertia markets. The discussion of additional value streams and hedging structures is particularly valuable for investors and asset owners. The argumentation is coherent and well-structured, though it is based on the presenter’s expertise and company data rather than independent research.

Scientific Rigor, Source Quality, Title Accuracy

The video demonstrates a high level of scientific rigor, with data presented from Modo Energy’s terminal and references to market forecasts and system operator data. The sources are not explicitly cited in the video, but the presenter mentions Modo Energy’s FCA-authorised indices and references to system operators (e.g., GB’s system operator, ERCOT, CAISO). The title accurately reflects the content, covering multiple markets as promised. The video is well-organized with clear chapters, and the presenter’s expertise is evident. The main limitation is the lack of external citations, but the data-driven approach and industry context lend credibility.
