🚨New @Policy_Exchange report, Powering Net Zero. Foreword by @BimAfolami, Chair of @PRASEG

GB electricity market isn't ready for more wind & solar:
▶️ Local electricity pricing can reduce costs
▶️ Reform support for renewables + back up supplies

🧵1/ https://policyexchange.org.uk/publication/powering-net-zero/
UK Government's programme of Electricity Market Reform (early-2010s) has driven a decade of progress.

🏭 Carbon emissions down >60% ⬇️
💷 Electricity bills ~flat ✅
⚡️ Blackouts largely averted ✅

2/
However, conditions during lockdown exposed flaws in the design of Great Britain's electricity market.

📉 Electricity demand fell 15%
📈 Market share of wind was higher than normal
💷 System balancing costs went ⬆️ by two thirds (+£220m)

3/
By 2050, wind and solar will provide most electricity in Great Britain.

Without reforms to the market, system balancing costs will rise as wind and solar grow.

4/
We propose four principles for the next stage of Electricity Market Reform.

Includes renewed focus on the "Energy Trilemma", which has gone out of fashion recently.

Energy Trilemma = Secure, affordable, low-carbon energy system.

5/
Government should make reforms in 3 areas
1⃣ Local electricity pricing in wholesale market
2⃣ 'Floor-price CfDs' for renewables
3⃣ Low-carbon quota in the Capacity Market

6/
1⃣ What is local pricing?

With local pricing, electricity prices will be different from town-to-town and at different times of day.

Will mainly impact wind farms, power stations and energy storage, but could also change how residential customers pay for electricity.

7/
Local pricing could save customers £2bn per year, or £50bn by 2050.

According to modelling by @AuroraER_Oxford, commissioned by @Policy_Exchange.

Could reduce average household electricity bill by £37 per year.

8/
Local pricing would help industry in coastal industrial hubs with lower energy prices.

▶️ Coastal hubs should benefit from lower energy prices as close to 🇬🇧 abundant offshore wind
▶️ Could boost green manufacturing, incl. low-carbon hydrogen, data centres, and green steel

9/
2⃣ Contracts for Difference (CfD) scheme also needs reform

▶️ Existing CfDs: generators have fixed price for electricity. Simple but distorts the electricity market.
▶️ Floor price CfD: exposes generators more to market prices.

10/
3⃣ Capacity Market (CM) must change to reduce support for gas-fired power stations.

▶️ Today, high-carbon power stations make up two-thirds of the CM.
▶️ By 2050, firm capacity needs to be mainly provided by low-carbon resources.

11/
Our proposals aim to be a second phase of Electricity Market Reform ('EMR 2')

Further reforms likely to be needed in the 2030s.
