CBAM Sector Brief · Electricity
CBAM compliance for electricity importers
Cross-border electricity imports into the EU are CBAM-scoped from the first MWh — no threshold. Carbon Border generates your NCA Authorised CBAM Declarant pack and reconciles interconnector flows with the relevant default or verified emission factor each quarter.
Who needs CBAM authorisation for electricity?
Any EU-established importer of electricity (CN 2716 00 00) via interconnector — including utilities, traders, large industrial consumers with cross-border PPAs, and aggregators. The de minimis threshold does NOT apply: 1 MWh triggers full reporting.
How embedded emissions are calculated
By default, embedded emissions equal the average grid emission factor of the country of origin (DESNZ for UK, ENTSO-E aggregations for others). Importers can claim a lower factor by providing verifier-signed evidence of a direct PPA with a specific generator (typically renewable). The 10% markup on default values applies in 2026.
In 2026, the EU default value carries a +10% markup when the importer cannot present verifier-signed supplier emissions. Verified data nearly always lowers your CBAM certificate liability — Carbon Border collects it for you via secure supplier portals.
Common HS / CN codes in this sector
Top origin countries currently subject to CBAM filings for this category include United Kingdom, Switzerland, Norway, Türkiye, Western Balkans.
UK CBAM (from 2027)
UK-to-EU electricity flows are CBAM-relevant today. Once the UK CBAM is live in 2027, EU-to-UK flows become subject to a mirrored regime. Carbon Border maintains a single interconnector ledger covering both directions.
What Carbon Border does for electricity importers
- Generates the full NCA Application Pack (Operational Capacity, Financial Exposure, HS-Code Alignment)
- Logs every shipment against the live ETS price and your verified emissions data
- Sends secure supplier portals so mills, smelters and producers upload signed emissions data
- Procures the right number of CBAM certificates each quarter via Stripe
- Maintains the 5-year audit trail required by Article 30 of Reg. (EU) 2023/956
- Mirrors the same workflow for the UK CBAM going live in 2027
Frequently asked questions
Does CBAM apply to electricity imported under a renewables PPA?
Yes, but the importer can substitute the grid default with the contracted generator's verified emission factor. The PPA must include physical delivery via a specific interconnector and a verifier statement covering the volume.
How are interconnector losses handled?
CBAM applies to electricity delivered into the EU bidding zone — interconnector losses on the non-EU side are already reflected in the upstream generation accounting and not double-counted.
Are short-term balancing flows in scope?
Yes. Any cross-border electricity flow registered by ENTSO-E or the relevant TSO as an import counts toward CBAM, regardless of contract type or duration.
What about Norway and Switzerland?
Both countries are in the EEA / EFTA but not in the EU ETS for CBAM-equivalent purposes. Imports from them are in CBAM scope. Norwegian imports benefit from very low grid factors when verified.
Will UK-to-EU flows still be CBAM-relevant after UK CBAM goes live?
Yes. EU CBAM continues to apply to UK→EU flows. UK CBAM will additionally apply to EU→UK flows from 2027, creating a mutually mirrored regime that Carbon Border handles in one ledger.
