What TownRock Energy can do for you?
TownRock Energy are a specialist geothermal energy consultancy and service provider. We have the skills to help you understand the renewable heating and / or cooling opportunities available from the ground beneath your site. We can assess how strong the commercial case is for installing a geothermal energy system; compare against other heat options such as air-source heat pumps; and help you select the right contractors. Our process ensures that the best type and size of system is installed, maximising quality whilst minimising your exposure to risk and cost. View our brochure to learn more about our services.
Project Phases & Decision Gates
We work with a diverse and wide array of clients, so our services are customised to fit each client’s needs. However, we apply a consistent approach to our site evaluations in a phased process that minimises risk and maximises the client’s return on investment. This process has four phases described below, giving example scope for an open-loop geothermal heat project:
| Phase 1.
Discover |
Feasibility Assessment: geothermal resource thermal energy potential, heat production options, techno-economic case with statistical range.
Decision to continue to planned and costed exploration activities in Prove stage |
2-6 months |
| Phase 2.
Prove |
Exploration Programme: non-intrusive geophysical surveys, intrusive boreholes drilled and tested, reservoir and geo-mechanical modelling.
Investment case developed, decision to continue to Deliver phase. |
6-18 months |
| Phase 3.
Deliver |
Design & Construct: production well drilling and testing, injection well drilling and testing, plant and pipework construction and commissioning.
Final contracting of heat delivery and O&M programme detailed |
12-24 months |
| Phase 4.
Operate |
Operate & Maintain: collect and analyse all operational datasets, comply with regulators, carry out routine pump and plant maintenance, optimise performance of wells and plant, delivery any necessary repairs.
Operate for 40+ years |
25-50+ years |
Additional Services
Closed-loop Ground-source Heat Pump Design
Is your thermal energy demand well balanced between seasonal heating and cooling? Is your heat demand too low to justify a large-scale open-loop geothermal project investment? We can design closed-loop borehole arrays to match any heat demand up to a few MW (small rural town). We can also source trusted drilling contractors and use our in-house thermal response test rig to test and analyse the heat resource from the first borehole installed to optimise design.
Water Source Evaluations
Is your water well or open-loop ground source heat pump not performing as expected? We can identify the problem by assessing sustainable flow rate, borehole temperature variations, water chemistry, pump performance and other issues, and offer a solution to improve your well / borehole. We also can deploy our in-house pump test rig for water well diagnosis.
Ground-source Heat Pump Improvement
Has your closed loop ground-source heat pump not been performing as expected? We can help identify the problem, and where possible design a cost-effective solution and recommend and oversee trusted contractors.
Thermal Conductivity Laboratory
Housed in the University of St Andrews, we own a tool which can measure the thermal conductivity of any rock or sample of unconsolidated material, which can be applied to better design a ground-source heat pump or deep geothermal energy system.
Building Energy Demand Modelling
For an existing or new commercial building, our technical experts can model the seasonal thermal energy demands, to predict the size and cost of heating and cooling generation required. We can then talk you through a number of renewable energy options and help you balance the installation and running costs with the environmental, economic and social benefits.
