Scope 2 and Solar PPAs

Scope 2 is electricity emissions. Buying through a PPA with REGO transfer lets you claim renewable electricity under the market-based method — provided your accounting is rigorous.

What this means

Scope 2 emissions are those from purchased electricity. Buying through a PPA with REGO transfer lets you claim renewable electricity under the market-based method — provided your accounting is rigorous and the REGO is genuinely retired against your consumption.

Actions to take

• Decide between location-based and market-based accounting (most use both).
• For market-based, ensure REGO certificates are explicitly assigned to your PPA contract.
• Audit REGO retirement annually via Ofgem registry.
• Disclose dual-reporting in environmental disclosures.

How PPA delivery fits

A solar PPA delivers measurable, audited renewable kWh from a known commissioning date — exactly the kind of evidence compliance frameworks want. The contract underpins the claim; the M&V annex provides the measurement.

What to negotiate into the PPA

• REGO certificate transfer (essential for market-based claims).
• Reporting cadence and format aligned with your compliance cycle.
• Audit trail support from provider (data feeds, certifications).
• Performance ratio guarantee with make-good if generation falls short.

FAQs

Scope 2 and Solar PPAs FAQs

Can a solar PPA on its own deliver compliance?

Not on its own — but it's typically the highest-impact single lever, especially for MEES and Scope 2. Combine PPA with LED + insulation + heat-pump for full compliance pathways.

How long before compliance deadline should I sign a PPA?

12-18 months minimum. PPA contracts take 6-12 months to sign and build. Add 3-6 months for measurement and verification before the deadline assessment.

Do PPAs always include REGO transfer?

Most do — but it must be explicit in the contract. Some standardised retail-PPA structures don't transfer REGOs by default; specifically negotiate this if you need the green claim.
