Geothermal for heat network developers and utilities

You have aggregated the demand. Now you need the cheapest low-carbon source across the life of the network, not the cheapest one to build. TownRock Energy shows heat network developers, ESCos, utilities and community energy groups where geothermal really sits on their scheme.

Let us start with the objection (and counter it)

Geothermal has higher capex and more subsurface risk than the alternatives you are weighing. Both are true. However here’s the other side of the story.

  • Lowest levelised cost of heat across the life of the network
  • Low electrical consumption
  • Boreholes designed to last 40+ years
  • The subsurface works as an inter-seasonal store, as well as a supply
  • No fuel logistics and no offtake agreement that can evaporate
  • Subsurface risk quantified and managed
  • A system that runs at high efficiency in the coldest weather, when demand peaks
  • Community-owned schemes welcome. We project-managed one of Scotland’s first

We have drilled almost 40 exploratory and operational boreholes, we hold the UK’s only private-company Heat Access Agreement, and we helped forge the modern UK permitting landscape alongside the Environment Agency and the Mining Remediation Authority. We develop no schemes for our own account and take no commission from equipment suppliers, so the recommendation follows the project economics.

Proof it runs, not just that it models

A 1.2 MWth mine water scheme operating since 2018 and the largest of its type in the UK. We built the world’s first mine water heat O&M programme around it, and auditing and re-drilling have since doubled generating capacity and halved maintenance costs.

Pre-FEED

Screening & due diligence

Concept designs, cashflow modelling and the visuals that go in front of decision-makers.

Commercialisation

FEED & permitting

Detailed design, permit applications, budget certainty ahead of FID.

Construction

Drilling & build
