About Tim

I am an Independent Energy Market & Regulatory Consultant specializing in UK power market reform, grid flexibility, and international project finance. With over 12 years of experience spanning the UK System Operator (ESO), European energy trading, and global development finance (ADB, World Bank), I bridge the gap between high-level government policy and commercial reality. I help consultancies, investors, and energy firms de-risk their portfolios, navigate complex frameworks like REMA and the Capacity Market, and unlock revenue streams in the transition to Net Zero.
