What the document changes
G.O. (Ms.) No. 01 dated 2 January 2023, issued by the Housing and Urban Development [UD4(1)] Department, amends rule 45 of the Tamil Nadu Combined Development and Building Rules, 2019. The appended notification was directed to be published in the Tamil Nadu Government Gazette Extraordinary dated 2 January 2023.
The amendment deals specifically with the location, separation and certification requirements for a Wind Electricity Generator, also described as a WEG.
Required distance from roads and other features
The amended rule requires a minimum distance between a Wind Electricity Generator and each of the following:
- Public roads.
- Railway tracks.
- Highways.
- High voltage electric lines.
- Buildings.
- Public institutions.
The minimum distance is calculated by adding:
- The tower height or hub height, measured in metres.
- Half the blade or rotor diameter, measured in metres.
- An additional 5 metres.
The required separation therefore depends on the measurements of the particular Wind Electricity Generator.
Protection for dwelling units
The amended rule states that a Wind Electricity Generator must not be erected within 500 metres of any dwelling unit. This provision is directly relevant to owners, occupiers and buyers of residential property near a proposed wind energy installation, as well as developers and operators selecting a location for a generator.
The source text does not describe how the 500 metre distance is to be measured or provide exceptions to the restriction.
Certification of plans
The amended rule requires the plan showing the micro-siting of Wind Electricity Generators within a site to be certified by the Tamil Nadu Generation and Distribution Corporation Limited.
The certification requirement also covers the specifications concerning:
- Development.
- Installation.
- Erection.
- Operation.
Property owners, project developers and professionals dealing with a proposed Wind Electricity Generator site should therefore check both the applicable separation distances and whether the required plan and specifications have been certified by the Tamil Nadu Generation and Distribution Corporation Limited.
