About Quantail

Engineering experience.
An owner’s view of value.

Quantail connects the physical realities of grid access to the commercial decisions an asset owner, developer or capital provider needs to make.

Founder

Henry Easterbrook

Engineer, developer and investor with twenty years across grid-connected energy infrastructure.

I built Quantail around questions I encountered in development and transactions: who will actually connect ahead of the project, which reinforcement will happen, and what does that mean for the investment?

Quantail brings proprietary modelling and senior judgement together so that a technical grid assessment can be followed through into revenue, valuation and the next decision.
