Source & plant sizing
Capacity, operating hours and annual yield for every source in the mix, including borehole fields, heat pumps, storage and peaking plant.
Area of expertise
Network source & system dimensioning
Expert sizing of geothermal, waste heat, solar and heat pump sources. We match the source mix, the plant and the pipe network to the load curve they actually have to serve.
What to expect
- Deliverable
- Sized scheme + hydraulic model
- Best used
- Before detailed design
An oversized plant is paid for twice — once to build, once to run
Source mix on the real load curve
We size each source against 8760 hours of demand, not a design-day peak, so base load, peaking plant and storage are split the way they will actually run.
Hydraulically verified
Pipe diameters, pressure loss, pumping energy and temperature regime are simulated across the whole network, so the scheme you cost is a scheme that works.
Phased to how connections arrive
Plant and network capacity are staged to the rate customers actually connect, so you are not financing capacity that sits idle for a decade.
4-step workflow
A rigorous, engineering-first sequence designed to take your district energy project from blank canvas to constructible, tender-ready reality.
Load curve build
Hourly heating and cooling demand for the perimeter, including simultaneity and future scenarios.
Source assessment
Available geothermal, waste heat, solar and ambient resources are quantified and ranked.
Sizing & simulation
Plant, storage and network are sized together, then hydraulically simulated end to end.
Phasing plan
Capacity staged across the build-out, with the trigger points for each extension.
What the study delivers
Everything it takes to design a tender-winning project
Hydraulic model
Pipe diameters, flow rates, pressure loss and pumping energy across the full network, delivered as a model you keep and can extend.
Temperature regime & control strategy
Supply and return temperatures, cascading opportunities and the control logic that keeps the source mix operating where it is efficient.
Phased build-out plan
Which capacity is installed when, what each phase costs, and the connection milestones that trigger the next one.
We needed a solution that could support our design decisions and optimize projects from the ground up. We're finally able to do just that — saving time, improving accuracy, and ensuring we make the best possible impact with each project.
