Domestic wind turbines limited to research purposes only

Home owners will be allowed to install a wind turbine for research purposes only, according to newly-approved planning guidelines.

Those who have already invested in this green energy technology may be allowed to keep their turbines by listing them for much-needed research.

The Malta Environment and Planning Authority board yesterday approved its planning guidelines on micro wind turbines that generate a maximum of 20 kilowatts of energy, which is roughly equivalent to what is consumed by a large household.

Over the years, a few eco-conscious consumers have installed such turbines on rooftops. However, neighbours often object to the noise generated by the rotating blades.

Given the noise element and the aesthetic and ecological considerations, Mepa last June issued a public consultation document for the drafting of the micro wind turbine policy.

The guidelines were approved by the Mepa board. It heard that a "precautionary" approach had been adopted primarily due to the lack of research on the noise and cumulative effects of small scale turbines. Once more research was compiled, the policies would be revised to include noise thresholds, among other things.

The approved policy guidelines that have still to be endorsed by the government distinguish between roof and tower-mounted turbines establishing a maximum height of 20 metres from ground level.

In the case of roof turbines, the height cannot exceed five metres from roof level. They cannot be located on the roofs of scheduled or listed buildings or on any property within a 30-metre buffer zone from such buildings.

In the case of structures outside a development zone, the turbines will only be allowed on large buildings so as to minimise the visual impact. Pastel colours are recommended with a preference for grey.

In cases where the turbine application falls within the migratory route or habitat of birds or bats, the permit will be subject to impact assessments.
