A Power Purchase Agreement is a long-term commercial commitment. The terms you agree today on price, indexation, contract length, break clauses, and technology risk allocation will govern your energy costs for the next 10, 15, or 20 years. Most businesses that enter a PPA receive advice from the PPA provider. That advice is not independent.
Arc Renewables acts as your independent PPA advisor. We are not a PPA funder, a developer, or an offtaker. We do not earn a commission from the PPA counterparty you appoint. We charge a fee for the advisory, and in return you receive advice that is shaped entirely by what is right for your business not by what is easiest or most profitable for the party on the other side of the table.
PPA advisory is increasingly demanded by organisations with procurement governance obligations: property funds, logistics operators with SBTi commitments, housing associations, and commercial landlords managing multi-site energy strategies. Arc has the commercial and technical capability to advise on all PPA structures across the UK market.
What is the Process of a Power Purchase Agreement for Solar Work?
1. On-site CPPA (Corporate Power Purchase Agreement)
A direct agreement between a developer and your business for solar generated on or adjacent to your site. Arc advises on counterparty selection, term structure, price indexation, and technology performance guarantees.
2. Sleeved PPA
A utility-intermediated structure where a licensed energy supplier manages the settlement between the generator and your organisation. Appropriate where your grid connection or procurement structure makes a direct CPPA complex. Arc advises on the utility’s sleeve margin and the risk transfer between all three parties.
3. Virtual PPA (vPPA)
A financial contract that provides price certainty without physical supply the generator and your organisation settle against a fixed strike price, with physical electricity sourced separately. Appropriate for multi-site organisations with complex supply arrangements. Arc advises on the basis risk, contract structure, and accounting treatment.
4. Funded PPA (developer-installed model)
A developer funds, installs, and operates a system on your site in exchange for a long-term supply agreement. Arc reviews the developer’s proposal, advises on the terms, and negotiates on your behalf. Arc is not the developer and has no interest in which developer is appointed.
Why Choose ARC Renewables for Your Solar PPA?
- PPA suitability assessment
Not every site or organisation benefits from a PPA. Arc’s starting point is an honest assessment of whether a PPA structure is the right option given your energy profile, procurement governance, financial position, and risk appetite compared to a capex-funded installation, a lease model, or continued grid supply.
- Structure advisory
Arc advises on which PPA structure on-site CPPA, sleeved, virtual, or funded is appropriate for your organisation and your sites, and what the commercial and risk implications of each are.
- Counterparty evaluation
Arc evaluates PPA developers and funders against technical capability, financial standing, contract terms, and track record. We run a structured procurement process that protects your position and gives you the market confidence that you have selected the right counterparty.
- Contract negotiation support
Arc reviews PPA contract terms and advises on the clauses that create the most risk for buyers indexation mechanisms, performance guarantees, step-in rights, and termination provisions. We negotiate on your behalf or alongside your legal team.
- Multi-site PPA programmes
For organisations with 10, 50, or 100+ sites logistics operators, housing associations, retail portfolios Arc advises on aggregation strategy, phasing, and counterparty bundling to maximise the commercial leverage of your portfolio scale.
Frequently Asked Questions – Power Purchase Agreements (PPA)
Does Arc provide PPA financing?
No. Arc does not finance, fund, or provide PPA structures. Arc advises your organisation on which PPA structure is right and manages the process of selecting and contracting with the right counterparty. This independence is what makes Arc’s PPA advice worth having.
How is Arc’s PPA advisory fee structured?
Arc charges a fixed advisory fee for smaller PPA mandates (from £3,000) or a percentage of the contracted PPA value for larger corporate programmes. The fee structure is agreed in the scope of work before any advisory engagement begins. Arc earns nothing from the PPA counterparty.
How long does PPA advisory take?
A PPA advisory mandate typically takes 4–8 weeks from initial assessment to signed contract, depending on the complexity of the structure and the counterparty procurement process. Multi-site programmes may take longer.
Can Arc help with Scope 2 reporting obligations?
Yes. PPA advisory is closely linked to SECR and TCFD Scope 2 reporting. Arc can advise on the reporting implications of different PPA structures and on green energy certificate strategy alongside the PPA advisory mandate.
