What the amendment governs
G.O. Ms. No. 1, Housing and Urban Development [UD4(1)], dated 2 January 2023, issued by the Housing and Urban Development Department of the Government of Tamil Nadu, changes requirements for the placement and approval of Wind Electricity Generators under rule 45 of the Tamil Nadu Combined Development and Building Rules, 2019.
The amendment was published in the Tamil Nadu Government Gazette Extraordinary on 2 January 2023. It was made by the Governor of Tamil Nadu using powers under the town and country planning, municipal, panchayat and city municipal corporation laws listed in the notification.
Who may be affected
The amended Tamil Nadu Combined Development and Building Rules, 2019 may affect:
- Owners or developers proposing to install or erect a Wind Electricity Generator.
- Owners or occupiers of dwelling units located near a proposed Wind Electricity Generator site.
- Persons assessing land near public roads, railway tracks, highways, high voltage electric lines, buildings or public institutions.
- Professionals preparing plans showing the micro siting, development, installation, erection or operation of Wind Electricity Generators.
Minimum separation requirements
The amended rule 45 requires the minimum distance between a Wind Electricity Generator and specified nearby features to be calculated using the following formula:
- Tower height or hub height, in metres.
- Plus half the blade or rotor diameter, in metres.
- Plus 5 metres.
This calculated distance must be maintained from public roads, railway tracks, highways, high voltage electric lines, buildings and public institutions.
A separate restriction states that a Wind Electricity Generator must not be erected within 500 metres of any dwelling unit. The notification does not provide a separate measurement method for this 500 metre restriction.
Certification of plans
The amended Tamil Nadu Combined Development and Building Rules, 2019 require the plan showing the micro siting of a Wind Electricity Generator within a site to be certified by the Tamil Nadu Generation and Distribution Corporation Limited.
The certification requirement also covers the specifications relating to the development, installation, erection and operation of the Wind Electricity Generator.
