UK Clean Power 2030 Action Plan: Sets capacity targets and grid reforms for a predominantly clean electricity system by 2030 Global Scope

What’s Required

1. Rapid renewable electricity deployment

The plan establishes indicative capacity ranges for the technologies expected to form the core of the 2030 electricity system:

1. 43 to 50 GW offshore wind.

2. 27 to 29 GW onshore wind.

3. 45 to 47 GW solar.

4. Continued nuclear generation where available.

5. Flexible low-carbon technologies.

6. Limited use of unabated gas for security of supply.

These are system-level policy ranges rather than individual company quotas.

2. Major grid expansion

The plan states that around twice as much new transmission network infrastructure will need to be built by 2030 as was delivered in the previous decade.

Relevant actions include:

1. New transmission infrastructure.

2. Distribution network reinforcement.

3. Faster grid investment.

4. Strategic network planning.

5. Connection queue reform.

6. Coordination between NESO, Ofgem, transmission owners and distribution network operators.

3. Grid connection reform

The government identified the existing connection queue as a major barrier. At the end of October 2024, the queue represented around 739 GW of generation and demand capacity, with many projects considered speculative or insufficiently mature.

The plan therefore supports moving away from a largely first-come, first-served approach toward prioritizing projects that are:

1. Ready to deliver.

2. Strategically aligned.

3. Consistent with Clean Power 2030 capacity ranges.

4. Needed in particular regions or technologies.

The updated connections annex states that alignment with strategic capacity ranges could release approximately 500 GW of network capacity and reduce the connection queue by around two-thirds, subject to Ofgem approval and final implementation.

4. Planning and consenting reform

The Action Plan identifies slow planning and consenting as a major delivery risk.

Measures include:

1. Prioritizing projects critical to Clean Power 2030.

2. Increasing planning system capacity.

3. Updating planning guidance.

4. Accelerating decisions on energy infrastructure.

5. Integrating onshore wind into the Nationally Significant Infrastructure Project regime.

6. Improving planning for networks and storage.

5. Battery storage

The government expects 23 to 27 GW of battery storage capacity by 2030, compared with around 4.5 GW installed when the Action Plan was prepared.

Actions include:

1. Prioritizing mature battery projects in connection reform.

2. Improving market access.

3. Reviewing planning treatment of grid-scale batteries.

4. Considering environmental permitting rules.

5. Supporting small-scale storage through wider consumer policies.

6. Long-duration electricity storage

The plan identifies a need for approximately 4 to 6 GW of long-duration electricity storage by 2030.

This may include technologies capable of shifting electricity over longer periods and supporting the system during extended periods of low renewable generation.

7. Consumer-led flexibility

The plan seeks significantly more flexible electricity demand.

Relevant areas include:

1. Smart appliances.

2. Time-of-use tariffs.

3. Smart heat pumps.

4. Electric vehicle charging.

5. Battery optimization.

6. Demand response.

7. Market-wide half-hourly settlement.

8. Electricity market reform

The Action Plan states that electricity markets must be reformed so that generation, flexibility and network incentives support the 2030 system.

Measures include:

1. Improving battery market participation.

2. Supporting consumer flexibility.

3. Capacity Market reforms.

4. Reviewing electricity market incentives.

5. Supporting investment in first-of-a-kind flexible clean capacity.

6. Continued use of renewable support mechanisms such as Contracts for Difference.

9. Supply chains and workforce

The government estimates that delivering Clean Power 2030 could involve around £40 billion per year of clean power investment for six years.

This creates requirements for:

1. Skilled labor.

2. HVDC cables.

3. Transformers.

4. Offshore wind components.

5. Grid equipment.

6. Battery supply chains.

7. Engineering and construction capacity.

8. Domestic manufacturing investment.

Important Deadlines

1. 13 December 2024: Clean Power 2030 Action Plan published.

2. April 2025: Connections reform annex updated to correct alignment between solar capacity allocations and the 2031 to 2035 pipeline.

3. Before the end of 2025: The original Action Plan expected updated connection offers to be issued under the reformed process, subject to regulatory approval.

4. 2026: Strategic Spatial Energy Plan expected to provide longer-term guidance beyond the interim 2035 capacity ranges used in connections reform.

5. 2030: Target year for delivery of the clean power system and associated capacity ranges.

6. 2050: Wider UK net zero objective remains the longer-term context for electricity-system transformation.

Current Status

The Clean Power 2030 Action Plan is active government policy. Its implementation is taking place through grid connection reform, planning changes, renewable allocation rounds, network investment, storage policy and electricity-market reforms.

Current status:

1. Clean power capacity ranges established.

2. Grid connection reform underway.

3. Planning reforms being implemented.

4. Renewable CfD allocation rounds continuing.

5. Battery and long-duration storage deployment being accelerated.

6. Supply-chain and skills constraints under active policy focus.

7. Electricity market reforms continuing.

8. 2030 remains the central delivery milestone.

Penalties for Non-Compliance

Because the Action Plan is primarily a government policy framework, it does not establish a single standalone penalty regime.

Enforcement instead occurs through the policies and regulatory mechanisms used to implement it.

Possible consequences include:

1. Loss of grid connection priority.

2. Refusal or delay of planning approval.

3. CfD contractual consequences.

4. Electricity licensing enforcement.

5. Environmental permitting enforcement.

6. Capacity Market penalties.

7. Loss of eligibility for government support.

8. Commercial delays from failing to meet project readiness criteria.

Examples of Known Violations / Failure Modes

Because the Action Plan is not itself a compliance code, the more appropriate focus is on implementation failure modes:

1. Claiming a project is strategically aligned with Clean Power 2030 without meeting connection criteria.

2. Holding speculative grid capacity without credible project delivery plans.

3. Missing project readiness or connection milestones.

4. Underestimating planning and consenting requirements.

5. Failing to secure supply-chain capacity for critical equipment.

6. Assuming renewable generation alone can deliver the 2030 system without storage, networks and flexibility.

7. Treating connection reform as automatic approval for a project.

8. Underestimating regional capacity limits for solar, onshore wind or batteries.

9. Ignoring network congestion and curtailment risk.

10. Presenting the 2030 target as a commitment to eliminate all gas generation.

11. Treating electricity decarbonization as equivalent to economy-wide net zero.

12. Overstating project climate benefits without considering lifecycle or environmental impacts.
