UK Electricity Act 1989 Section 36: Generating Station Consent Guide
Updated 6 September 2026 · By SolarNevs Research Desk, Dealer surveys + verified sources · 1 source · Method ↗

Key Takeaways
- Section 36 of the Electricity Act 1989 provides that electricity generating stations cannot be constructed, extended, or operated without statutory ministerial consent.
- Establishes a 50 megawatts permitted capacity threshold in England and Scotland, exempting sub-50MW solar farms to local planning authority regimes.
- Enforces a 350 megawatts devolved capacity threshold for generating stations situated in Wales.
- Disapplies Section 36 consent requirements where solar projects secure Development Consent Orders under the Planning Act 2008.
- Empowers the appropriate authority to issue orders making differentiated provisions for distinct generating station classes.
Statutory Purpose of Section 36
Enacted under the Electricity Act 1989 (c. 29), Section 36 serves as the primary statutory foundation for regulating major power plant construction and grid additions across Great Britain.
For utility-scale solar developers, Section 36 defines the legal boundary between local Town and Country Planning Act applications and ministerial or national infrastructure planning regimes.
Statutory Capacity Thresholds & Jurisdiction Matrix
The statutory consenting pathway depends on generation capacity and geographic jurisdiction:
Regulatory Category | Statutory Provision | Siting & Consenting Pathway for Solar Farms |
|---|---|---|
Permitted Capacity (England & Scotland) | Capacity does not exceed 50 megawatts | Governed by Local Planning Authorities (Town and Country Planning Act 1990 / 1997) |
Major Generation (>50MW England) | Subject to Section 33(1) of Planning Act 2008 | Nationally Significant Infrastructure Project (NSIP) requiring Development Consent Order (DCO) |
Major Generation (>50MW Scotland) | Section 36 consent granted by appropriate authority | Consented directly by Scottish Ministers via the Energy Consents Unit (ECU) |
Devolved Capacity (Wales) | Capacity does not exceed 350 megawatts | Developments of National Significance (DNS) consented by Welsh Ministers |
Station Operation Consent | Disapplied if authorized by DCO under Planning Act 2008 | Avoids double-consenting once formal infrastructure consent is granted |
Strategic Planning Steps for UK Solar Developers
To ensure compliance with Section 36 and planning frameworks:
- Evaluate 50MW Siting Boundary: Structure sub-50MW solar arrays to ensure peak AC inverter export capacity strictly does not exceed 50 megawatts.
- Navigate DCO Regimes for Large Assets: For installations exceeding 50MW in England, execute statutory pre-application community consultations under the Planning Act 2008.
- Secure Deemed Planning Directions: Where Section 36 consent is granted in Scotland, secure concurrent deemed planning permission directions under Section 90 of the Town and Country Planning legislation.
Frequently asked questions
What is the primary consent requirement under Section 36 of the Electricity Act 1989?
Under Section 36(1), a generating station shall not be constructed, extended, or operated except in accordance with a consent granted by the appropriate authority (August 2026).
What capacity threshold triggers the Section 36 consent requirement outside Wales?
Under Section 36(2)(a), the requirement does not apply to generating stations whose capacity does not exceed the permitted capacity of 50 megawatts (August 2026).
What is the devolved capacity threshold for generating stations in Wales?
Under Section 36(2)(c), generating stations in Wales are exempt from Section 36 consent if their capacity does not exceed the devolved capacity of 350 megawatts (August 2026).
How does Section 36 interact with the Planning Act 2008 Development Consent Order regime?
Under Section 36(1A) and (1B), the requirement for Section 36 consent is disapplied where construction, extension, or operation is authorized under the Planning Act 2008 (August 2026).
