Energy storage and flexibility

Flexibility needs on the system are changing radically, with increasing needs for energy storage, alternative low-carbon flexibility assets and technical solutions to ensure a secure system is maintained as we progress towards Net zero targets. 

These changes mean an opportunity for the multitude of assets to provide flexibility to National Grid ESO and local DNOs, with all parties moving towards market-based short-term procurement frameworks. Whilst this opportunity is growing for many technologies, understanding the various flexibility revenue streams, technical requirements, and business models is a major hurdle to development. 

Cornwall Insight’s ‘Energy storage and flexibility services’ are designed to answer these questions and support developers, asset owners and investors in operating across these markets. Our expertise cuts across the challenging techno-economic aspects of this sector, with our market-leading analysts including experienced revenue forecasters, BSC and CUSC panel members and policy experts. 

The team provides solutions to the key questions in the flexibility sector through three key support areas: 

  • Market forecasts: including long-term power curves, network cost forecasts and flexibility revenue forecasts (frequency markets, reserve markets, Capacity Market).
  • Regulation and policy analysis: on the latest changes impacting flexibility assets through our tailored alerts, impact reports and monthly ‘Flexibility forum’.
  • Routes to market and competitor intelligence: PPA and trading price benchmarks for flexible asset PPAs, forecasts and competitor intelligence across battery and gas peaking markets.
