Crucial intelligence for developers and investors in battery storage and flexible assets in GB


The GB energy system is becoming increasingly dominated by renewables, leading to greater market volatility and system stability issues. Flexible energy technologies like battery storage, peakers or demand side response are well placed to solve these challenges.

Cost declines and innovative business models are enabling them to play a key role in the future.


Flexibility is a huge opportunity, but participants face challenges from complex business models, policy change, and uncertain future revenue streams. In particular, the lack of contracted revenues for flexible assets creates a challenge in understanding and quantifying risk, impacting the financing of such assets.

An understanding of fundamental market characteristics, how to monetise assets and innovation in finance structures are required to successfully deploy flexible technologies.


We have supported over 70% of GB installed battery capacity, over 2GW of gas recips, and worked with the largest DSR providers. We model complex revenue streams, eg optimised trading across multiple energy markets, and quantify and assess merchant risk and potential upside for project economics.

Our GB Flexible Energy service provides subscribers with a toolkit and all necessary forecasts to understand and participate in flexibility markets.
