How does the PPA structure actually work?

Saber funds and owns the infrastructure on your site under a single Power Purchase Agreement, and is accountable for its delivery and operation, coordinated through specialist partners. You pay a contracted rate per kWh for the energy generated, CPI-indexed annually. Zero capital outlay. Structured as an operating expense, off the balance sheet. Term is 10 to 25 years. At the end of the term the agreement can be extended, or the asset's future agreed with you.

What does the first-step engagement involve?

An introductory call with the platform team to understand your situation, the estate and the dominant commercial driver. From there, we agree the next step together. For most engagements that means a structured data exchange (typically 12 months of half-hourly consumption and a basic site pack) and an indicative blend, savings range and delivery timeline within one to two weeks. The conversation always comes first.

Who carries the deployment risk?

Saber. Planning, grid liaison, technology selection, partner coordination, equipment performance and operational risk all sit with us for the full PPA term, funded by committed senior debt from Pollen Street Capital. The customer keeps operational decisions, site access and strategic energy direction.

How is this different from a developer asking for the project to be sold on?

The PPA is signed with SRE Capital, a dedicated long-term asset ownership vehicle, not a developer that intends to flip the project. Senior debt is committed at platform level, not raised per project. Saber owns and operates the infrastructure for the full term. The interests are aligned with long-term performance, not transaction.

Distributed energy infrastructure

Lower energy costs. Defensible decarbonisation. Zero capital outlay.

Saber designs, funds and operates blended on-site generation behind the meter. One Power Purchase Agreement. A contracted rate below the grid, CPI-indexed, for 10 to 25 years. Capital preserved, risk transferred.

Arrange a conversation How we work

What changes for you

Demand-driven, not technology-led.

Before we recommend anything, we analyse your business estate against verified half-hourly data: consumption, infrastructure, grid position and thermal demand.

Then we design for the right commercial and environmental outcome, whether that is a blend of technologies or a single one. The same approach holds for one facility or a national estate of hundreds.

Every solution is funded through a Saber commercial PPA. One contract and a single point of accountability, from site assessment to live operations.

Cost certainty

Below-grid pricing from day one, contracted and CPI-indexed across the term. Total energy cost certainty against wholesale market volatility.

Decarbonisation pathway

Defensible Scope 1 and 2 reductions backed by metered generation data. A credible pathway, with an auditable evidence pack for the CSO.

Operational resilience

On-site generation behind the meter reduces grid dependency. Across a multi-site estate, distributed generation strengthens energy security.

Asset value protected

Under-used roof and land monetised, EPC ratings improved, and asset value protected across the PPA term. No capital commitment, no depreciation schedule.

Where the cost actually sits

Three problems one contract has to solve.

The unit rate hides the real number

Procurement optimises the pence per kWh. The bill that lands is a total: commodity, network charges, levies and capacity payments, across a profile that peaks when power is dearest. Taking a penny off the rate does nothing about the shape driving the cost.

Your demand has a shape. Most offers ignore it.

A single technology gets sized against an annual total, then meets a site that runs shifts, holds thermal load overnight and peaks after dark. Solar PV on its own leaves the evening untouched, and the gap fills at the grid price.

The connection queue sets your timeline

Growth plans wait on a DNO date you do not control. Where the queue blocks the site, the answer has to generate behind the meter from day one, on your programme rather than the queue.

So we start with the profile, not the product. Twelve months of half-hourly data sets what generates, what stores and what stays on the grid.

Annual energy mix, manufacturing

% of annual demand | 79% generated on site

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.

How we work

Designed, funded, delivered, monitored.

The same structured approach for every project, from a single facility to a national estate of hundreds. The customer signs one document and pays for metered output.

Assess

Half-hourly consumption analysis and technical screening. Every location scored against feasibility criteria. Indicative blend and economics returned within one to two weeks.

Design

Site walks confirm what the data shows, then the right blend for your profile: Solar PV, Hydrogen-ready CHP, BESS, Wind or Heat pumps in the combination that delivers the best commercial outcome. The blend can evolve over the term.

Fund

Saber funds, owns and operates the infrastructure under a single PPA. Zero capital outlay. Structured as an operating expense, off the balance sheet.

Deliver

Specialist partners coordinated through the Saber Intelligence Platform. Each site progresses through defined stages with clear accountability. Sites come online on your programme, not the DNO queue.

Monitor

Live telemetry tracks generation and performance. Automated billing on metered output. ESG analytics deliver defensible Scope 1 and 2 reduction data, validated for SECR, CSRD and SBTi.

The commercial case

Unit rate is the wrong comparison.

The correct question is total annual energy cost across the full consumption profile, not the unit rate applied to a limited generation volume.

Illustrative: modelled against a real UK multi-site profile

Non-commodity charges are the larger half of the bill and they do not fall in step with generation, which is why the total never falls as far as the unit rate suggests.

25% to 35% off for blended profiles, 10% to 15% for solar-led estates

Technology stack

Solar PV. Hydrogen-ready CHP. BESS. Wind.

The building blocks. Heat pumps add in for sites with thermal profiles that do not match a CHP application. The blend can evolve over the PPA term, so customers lock into a long-term contracted decarbonisation pathway that flexes with the site roadmap, not a single technology stack at signing.

Solar PV

Daytime generation displacing grid import. Strong fit on daytime-weighted loads where roof or land availability supports private-wire deployment.

Hydrogen-ready CHP

The workhorse where sites have simultaneous heat and power demand. Up to 96% total efficiency with usable thermal recovery. Hydrogen-ready engines transition as supply becomes available.

BESS

Battery storage where the demand profile and PPA structure benefit from time-shifting, peak management or resilience. Captures surplus generation and smooths peak tariff exposure.

Wind

Assessed at feasibility. Strong fit where regional capacity factors, site conditions and land position support it. Particularly relevant for agricultural and rural commercial sites.

Where Saber works hardest

Built around how your industry actually buys energy.

Different sectors lead with different drivers. Hover or tap a sector to see how the blend, the contract and the deployment programme adapt to the way that industry runs.

Solving the grid queue

Saber Bridge to Grid. Day-one power, ahead of the DNO queue.

DNO connection timelines now stretch into multi-year horizons. For data centres, manufacturing growth, logistics expansion and motorway services electrification, that delay sits on the critical path.

Saber Bridge to Grid removes it. Hydrogen-ready CHP-led private-wire power delivered under a PPA, sized to your day-one demand. The asset transitions to a peaking, resilience or heat-led role once the grid is energised, all under one contract.

Site comes online on the operator’s programme, not the DNO queue’s.
