The challenge

Motorway service areas face a multi-megawatt step-change in demand as EV charging scales. The new load arrives faster than the grid can reinforce, and DNO connection queues sit directly across the path of the charging ramp. Across a portfolio, the same problem repeats at every site, which makes site-by-site procurement slow and inconsistent.

How Saber addresses it

Saber assesses the estate as a single programme rather than a sequence of sites. Hydrogen-ready CHP, Solar PV and BESS are blended to handle day-one demand and the EV charging ramp under one structure, with Bridge to Grid removing the DNO queue from the critical path. A single-site feasibility takes roughly one to two weeks; a full portfolio assessment runs at roughly three months. Estates of this kind are assessed as one programme, not site by site.

A day on site

What the blend does across a working day.

Site demand met by Hydrogen-ready CHP, Solar PV, BESS, with residual grid import at the shoulders. Every half-hour is metered, recorded and reported.

Illustrative annual energy mix, shown as a share of site demand. Every unit generated on site is supplied at the contracted PPA rate rather than the grid rate, so savings scale with the on-site share. BESS is a routing stage, not a source: battery discharge is generated earlier by Solar PV or Hydrogen-ready CHP. Round-trip efficiency assumed at 88%; the on-site share is stated net of those losses and the generation bars are gross.
