UK Renewable Energy Guarantees of Origin (REGO)
Renewable Energy Guarantees of Origin (REGO): Clear, credible proof of UK renewable electricity
A REGO = 1 MWh of eligible UK renewable generation. Suppliers use REGOs to evidence the
renewable share of their annual Fuel Mix Disclosure, and corporates use them for transparent reporting and claims. :contentReference[oaicite:1]{index=1}
How it works
Interactive map
EU GO sources
Operator: Ofgem
Register: Renewables & CHP
Disclosure: Annual FMD
Key takeaways
- REGOs underpin GB & NI Fuel Mix Disclosure every year. :contentReference[oaicite:2]{index=2}
- Since 2021, EU does not recognise UK‑issued REGOs; mutual UK‑EU recognition is being discussed but remains uncertain. :contentReference[oaicite:3]{index=3}
- Prices and liquidity are cyclical; methodology rollovers (Platts CP periods) affect quotations and reporting. :contentReference[oaicite:4]{index=4}
Certificate unit
1 REGO = 1 MWh
Issued per MWh of eligible generation. :contentReference[oaicite:5]{index=5}
Primary use
Fuel Mix Disclosure
Annual supplier disclosure in GB. :contentReference[oaicite:6]{index=6}
Registry

EU status
Not recognised
Post‑Brexit non‑recognition by EU. :contentReference[oaicite:8]{index=8}
How REGOs work (end‑to‑end)
1) Metered generation → Issuance
Generators (or agents) submit readings; Ofgem issues REGOs into the Renewables & CHP Register. :contentReference[oaicite:9]{index=9}
2) Transfer & trade
REGOs move between accounts; can be bundled with power or traded unbundled for disclosure/claims. :contentReference[oaicite:10]{index=10}
3) Retirement for claims
Suppliers retire REGOs for Fuel Mix Disclosure (annual), corporates for voluntary reporting. :contentReference[oaicite:11]{index=11}
4) Cross‑border considerations
UK REGOs are not accepted in EU GO registries post‑2020; UK still recognises some EU GOs domestically subject to policy. :contentReference[oaicite:12]{index=12}
Compliance calendar (GB Fuel Mix Disclosure)
By 1 July
Suppliers check they hold required REGOs for the round. :contentReference[oaicite:13]{index=13}
By 1 Aug
DESNZ publishes the Fuel Mix Disclosure Data Table. :contentReference[oaicite:14]{index=14}
By 1 Oct
Suppliers publish their annual Fuel Mix Disclosure. :contentReference[oaicite:15]{index=15}
Price rollovers
Platts CP rollover now on/around 2 July each year (CP‑24 → CP‑25, etc.). :contentReference[oaicite:16]{index=16}
Tip: align corporate reporting snapshots with certificate vintage/compliance period to avoid mismatches.
Market pulse: volumes & prices
- Pricing has been volatile: highs in 2023, then notable declines into 2024/25 as issuance rose and expectations shifted. :contentReference[oaicite:17]{index=17}
- Vendors and analysts note periods of undersupply alternating with easing; keep an eye on compliance‑period spreads (current vs. forward vintages). :contentReference[oaicite:18]{index=18}
- Press reports in mid‑2025 flagged deadline adjustments and active FMD housekeeping by suppliers. :contentReference[oaicite:19]{index=19}
| Theme | What to watch | Why it matters |
|---|
| Compliance period (CP) rollovers | Quoted CP (e.g., CP‑24) & rollover date | Affects which vintage is “current” for pricing. :contentReference[oaicite:20]{index=20} |
| Issuance pace | New wind/solar/hydro output | Supply growth can ease prices. :contentReference[oaicite:21]{index=21} |
| Policy talks | Potential UK‑EU recognition path | Could expand liquidity; timeline still uncertain. :contentReference[oaicite:22]{index=22} |
Interactive map: REGO & related issuing bodies
This map is accurate to the REGO reality (UK issuance) and still global‑ready. It: (1) pins UK/Ofgem as the REGO domain, (2) lets you import your sheet to show GO / I‑REC / REC issuing bodies and any REGO recognition/retirement links you want to illustrate.
How to load your sheet: publish your Google Sheet as CSV and paste the CSV URL below (field order required: country, lat, lon, scheme, issuing_body, body_url, contact_email, linkedin, note).
Buyer’s checklist
- Match vintage (production period) to claim period; avoid stale certificates.
- Retire to the correct account & keep proof for audits.
- If you operate in the EU, use GOs; don’t assume UK REGOs will be recognised there. :contentReference[oaicite:23]{index=23}
FAQ
Are REGOs the same as EU GOs?
No. REGOs are UK‑only. EU uses GOs under the AIB EECS framework. :contentReference[oaicite:24]{index=24}What’s the unit of a REGO?
1 certificate per 1 MWh of eligible renewable electricity generated. :contentReference[oaicite:25]{index=25}Can a UK REGO be used in the EU?
Not since 1 Jan 2021. Discussions on mutual recognition exist but no firm timeline. :contentReference[oaicite:26]{index=26}What registry is used?
Ofgem’s Renewables & CHP Register (issuance, transfer, retirement). :contentReference[oaicite:27]{index=27}Best EU GO sources (for cross‑reference)
- AIB (EECS framework, domain protocols & stats). :contentReference[oaicite:28]{index=28}
- ACER & CEER market monitoring and retail reports. :contentReference[oaicite:29]{index=29}
