Energy storage and flexibility

We are at the forefront of the energy storage and flexibility sector, helping customers successfully deploy battery storage, flexible power generation and demand-side response. In addition, we provide strategy and business case development, revenue forecasting and commercial and regulatory investment due diligence.

Through our team’s continual market monitoring, we can ensure our customers are fully up-to-date with the “need to know” information for flexible assets on the system, enabling developers and investors to deploy assets and capital with confidence. Our revenue forecasting capabilities cover all applicable revenue streams and are fully configurable for the parameters of different assets.

Cornwall Insight supports with:

  • Revenue forecasting for flexible assets, covering revenues from the wholesale power market, established balancing services and emerging system stability services
  • Regulatory and commercial investment due diligence, with our services having been used to raise debt for several transactions
  • Strategic support on asset sizing, storage duration, asset optimisation and co-location

Our recent report, commissioned by the Climate Change Advisory Council, Ireland, assesses the potential for Long Duration Energy Storage technologies (LDES) in Ireland, focusing on barriers and opportunities for the sector. The report focuses on policy, regulatory and market-based opportunities and challenges, as the first step in understanding the market landscape for the sector.

Case study

Battery storage revenue modelling

Zenobe | December 2019

Zenobe is a major owner and operator of battery storage in the UK. Cornwall Insight assisted Zenobe in securing debt facilities to develop further battery storage assets, with a value of £25m being secured from Santander Corporate and Commercial. We were part of the project team to assist in the debt facilitation process and provided market analysis and forecasting to allow Santander to be comfortable with the provision of debt.

We provided forecast revenues for battery storage assets in the UK market, utilising our in house battery storage optimisation modelling. As part of this process, we ran a number of sensitivity scenarios across several different price curves, allowing the client and the investor to have as robust a view as possible for long-term battery revenue streams, including Wholesale Day-ahead and Intraday trades, the Balancing Mechanism and the Capacity Market. As part of this process, an assessment was also given of the regulatory risks associated with developing a battery asset, and further price curves.
