G.O.(Ms).No.01, Amendment to rule 45 of Tamil Nadu Combined Development and Building Rules, 2019, 2023
The Housing and Urban Development [UD4(1)] Department issued G.O.(Ms).No.01, dated 2 January 2023, to amend rule 45 of the Tamil Nadu Combined Development and Building Rules, 2019. It changes minimum separation requirements for Wind Electricity Generators, adds a 500 metre restriction near dwelling units, and requires micro siting plans and technical specifications to be certified by the Tamil Nadu Generation and Distribution Corporation Limited.
What the government order changes
G.O.(Ms).No.01, dated 2 January 2023, issued by the Housing and Urban Development [UD4(1)] Department, amends requirements for the development, installation, erection and operation of Wind Electricity Generators under the Tamil Nadu Combined Development and Building Rules, 2019. The notification was ordered to be published in the Tamil Nadu Government Gazette Extraordinary dated 2 January 2023.
The amendments were made using powers under the Tamil Nadu Town and Country Planning Act, 1971 and several laws governing municipalities, panchayats and city municipal corporations in Tamil Nadu.
Minimum distance from roads, buildings and infrastructure
The amended rule sets a formula for the minimum distance between a Wind Electricity Generator and specified nearby features.
The minimum distance must be:
- The height of the tower or hub height, measured in metres.
- Plus half the diameter of the blade or rotor, measured in metres.
- Plus 5 metres.
This calculated distance applies between a Wind Electricity Generator and:
- Public roads.
- Railway tracks.
- Highways.
- High Voltage electric lines.
- Buildings.
- Public institutions.
Because the required distance depends on the generator's tower or hub height and blade or rotor diameter, the source does not provide one fixed separation distance for every installation.
Restriction near homes
The amendment states that a Wind Electricity Generator must not be erected within 500 metres of any dwelling unit. This provision is relevant to owners, residents, buyers and developers assessing whether a proposed wind generator can be placed near a home.
The source does not describe exemptions, measurement methods or a procedure for seeking relaxation from the 500 metre restriction.
Certification of wind generator plans
A plan showing the micro siting of Wind Electricity Generators within a site must be certified by the Tamil Nadu Generation and Distribution Corporation Limited.
The certification requirement also covers the generators' specifications concerning:
- Development.
- Installation.
- Erection.
- Operation.
Developers and site owners planning Wind Electricity Generators therefore need certification from the Tamil Nadu Generation and Distribution Corporation Limited for the site plan and relevant specifications.

What distance must a wind generator maintain from a public road or building?
The minimum distance is the tower or hub height, plus half the blade or rotor diameter, plus 5 metres. The same formula applies to public roads, railway tracks, highways, High Voltage electric lines, buildings and public institutions.
Who must certify the micro siting plan for Wind Electricity Generators?
The Tamil Nadu Generation and Distribution Corporation Limited must certify the plan showing micro siting within the site and the specifications concerning development, installation, erection and operation.
Does the amendment give one fixed distance for all Wind Electricity Generators?
No. For roads, railway tracks, highways, High Voltage electric lines, buildings and public institutions, the required distance depends on the tower or hub height and the blade or rotor diameter. A separate fixed restriction of 500 metres applies from any dwelling unit.
