Pathfinder Clean Energy has taken the final investment decision on Tophams, a 55MWp solar farm paired with a 22.6MWh battery in North Hertfordshire, backed by a 20-year Contracts for Difference agreement

Construction starts this year with commercial operation targeted for the second half of 2027, financed through a euro100 million convertible bond secured in June, another sign that new utility-scale solar in the UK is now routinely built with storage attached from day one.

Pathfinder Clean Energy has reached final investment decision on Tophams, a 55MWp solar farm co-located with a 22.6MWh battery in North Hertfordshire. Construction is set to begin this year, with commercial operation targeted for the second half of 2027. The project secured a 20-year Contracts for Difference agreement through the AR7a auction round, giving it a fixed revenue floor for the life of the asset, and financing came via a 100 million euro convertible bond arranged in June.

The size and structure here are unremarkable on their own, a 55MW solar-plus-storage project is a fairly standard entry in the current utility-scale pipeline. What's worth noting is how routine that pairing has become. As with the Kentishes approval in Essex earlier this month, storage isn't an add-on anymore, it's built into the FID case from the start. CfD-backed projects increasingly need to demonstrate they can firm up output to compete for auction slots, and lenders are underwriting solar-plus-battery as the default structure rather than the exception.

For homeowners in Sandwich, projects at this scale don't translate into a scheme or grant you can apply for. What they do is add to the pipeline of utility-scale connections competing for capacity on the same regional grid infrastructure that domestic MCS installs also depend on. Hertfordshire isn't on the same DNO patch as Kent, but the pattern, more large co-located projects reaching FID and needing grid connections, is the same one this site has flagged in coverage of DNO connection delays in the South East.

Nothing here changes what a homeowner should do this week. It's a useful marker of direction, though, utility-scale solar is being built with batteries as standard now, not as an afterthought, and the same logic increasingly applies at the domestic scale too. Worth watching whether Ofgem's grid-connection reforms keep pace with the volume of projects like Tophams now clearing FID.
