The challenge

Retail estates face compounding energy costs across dozens or hundreds of locations. Customer expectations and investor ESG scrutiny are tightening at the same time, so the estate needs a programme that reduces cost and produces evidence at portfolio scale, not site by site.

How Saber addresses it

Retail sites with suitable roof area and consistent daytime demand are natural candidates for Solar PV, with BESS assessed at feasibility. Saber profiles the estate as a single programme, scoring every site on its own half-hourly consumption profile and its roof asset rather than working from a generic template. The PPA structure means no capital allocation, and the estate reports through one commercial relationship.

A day on site

What the blend does across a working day.

Site demand met by 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.
