More from Brexit
What's in the EU-UK Brexit deal on energy?
It may be Boxing day, but I've had a quick look
Title VIII: Energy is the key section (page 156 onwards)
▶️ Standard stuff on commitment to competition, unbundling and customer choice
▶️ UK Capacity Market no longer needs to try to integrate overseas Capacity providers & vice versa
(Article ENER.6, Clause 3, page. 160)
2/
▶️ Existing "exemptions" for selected interconnectors will continue to apply.
This means that these interconnectors can continue to sell capacity rights ahead of time, rather than all through close to real-time markets.
(Article ENER.11, page 162)
3/
▶️ No network charges on individual interconnector transactions (as now)
▶️ But, UK cannot participate in EU procedures for capacity allocation and congestion management (more on this later)
(Article ENER.13, page 163)
4/
Gas trading: looks like the UK stays in the existing PRISMA gas trading platform.
Not my specialist area, but is this because PRISMA isn't an EU institution (unlike electricity market coupling)?

Been waiting for 👇 🚨
Important story on what a “tariff-free” deal means in practice and why it’s not enough for two economies as closely integrated.
Tariffs are removed on goods that meet rules of origin. This is a complex and nuanced area of customs.
/1
Important to remember that trade deals (FTAs) weren't designed with such a high degree of economic integration in mind.
So some of the standard RoO provisions will seem incredibly restrictive under the UK-EU deal.
/2
Minimal operations or insufficient processing is a standard part of an FTA. Most, if not all FTAs, include a provision on minimal processing – processing not considered sufficient to confer originating status even if rules of origin have been met.
/3
It is standard procedure not to apply cumulation when goods have only been subject to minimal processing.
To be able to cumulate origin and consider the final product of UK origin, the processing carried out in the UK needs to exceed minimal operations.
/4
The level of integration between the UK and the EU means that this will have significant consequences for a number of industries.
For example, in supply chains where goods are brought into the UK from the EU and reassembled, sorted or repackaged and re-exported to ROI.

A bellwether? \U0001f62c Stay with me. 1/
