Sites consuming at medium or high voltage have real flexibility and nobody to take it to market. The fixed band fixes the cost, absorbs the imbalance, and takes that flexibility to mFRR.
A medium or high voltage site buys indexed energy, pays for contracted capacity, and runs processes that can shift in time without affecting operations. That flexibility never reaches the market because the status and the operation to take it there are missing.
The cost of system services passes through to the consumer’s bill. Regulation charges rose more than 60% between 2023 and 2025. Source: REN.
A reference consumption profile and a tolerance band are agreed. Inside the band the cost is the agreed one and there is no imbalance to bear. Timing, cycles and imbalance management sit on our side.
Above that, whatever flexibility the site can offer is taken to mFRR and the result is shared.
Industry at MV and HV. The reference is the agreed baseload, with tolerance. Shiftable processes, industrial refrigeration and on-site generation enter the same perimeter.
Electric mobility. At a charging hub the reference cannot be baseload: it is the energy delivered to vehicles, which is the number the operator already measures and bills. We guarantee a cost per kWh delivered, within a volume band. The largest value driver is capacity — flattening the peak reduces contracted capacity and can avoid or defer a connection reinforcement, which is capital expenditure, not operating cost. Not all points are worth the same: a fleet depot with ten hours of window for two hours of charging is near-perfect flexibility; a high-power corridor with twenty-minute sessions has all its value in the battery and in the peak.
Telecommunications. A tower site is close to baseload — flat and predictable, the ideal case for the fixed band. Every site has a backup battery bank that is almost always idle, already bought and connected, and centralised telemetry already installed. Here aggregation is the product: one site is a few kW and makes no bid at all; thousands of sites are tens of MW, and geographic spread makes the portfolio more reliable than a single asset. The battery only enters above a contractually fixed reserve level, and stays out of the market under a grid alarm, adverse weather forecast or maintenance. Autonomy is a service commitment and is not touched.
We do not finance or install the client’s equipment. We do not swap batteries, inverters or hardware in exchange for flexibility rights. Equipment condition is a qualification criterion, not an investment opportunity of ours.
What we sell is optimisation, imbalance management, representation and market access.
