Offshore windfarm companies may be exempted from new UK nature rules in an attempt to keep down the cost of renewable energy, the Guardian has learned.<\/p>\n
The energy firms have said they would be unable to build the vast number of turbines required to meet the government\u2019s green electricity goals if they have to meet new rules for nationally significant infrastructure projects (Nsips).<\/p>\n
The energy secretary, Ed Miliband, is trying to find ways to reduce the cost of building offshore wind projects to avoid an increase in energy bills, according to sources in his department. Inflation and labour and materials costs are making it expensive to build the projects<\/a>, while the grid upgrade required<\/a> to carry the extra electricity is also adding to costs.<\/a><\/p>\n Under new planning rules<\/a> from the Department for Environment, Food and Rural Affairs (Defra)expected to be brought in May, all Nsips such as nuclear power plants, airports and road schemes will have to enhance nature when new projects are built, or when existing infrastructure is expanded.<\/p>\n Under the biodiversity net gain (BNG) requirement, they will be required to create 10% more nature than was there before the project was started, whether by planting trees or wildflower meadows or creating wetlands. The additions will not necessarily have to be in the same location as the development.<\/p>\n The rules were supposed to be published last week after a consultation, but the announcement has been delayed after a last-minute loophole was added for offshore windfarms to make them exempt from BNG rules, sources say. The turbines will not have to compensate for habitat destroyed in the shallow intertidal waters in which they are built, which include prime feeding spots for seabirds such as puffins, where the fish they feed on spawn.<\/p>\n Puffins are one of the bird species potentially affected by offshore windfarms.

We are currently analysing responses to the consultation and will publish a government response in due course.\u201d<\/p>\n In a submission to the consultation, the industry group RenewableUK said: \u201cIt is essential that mandatory BNG does not create an imbalance of priorities, discouraging renewable project developments that contribute to climate change mitigation\u201d and that there were fears it could add \u201cdisproportionate costs or legislative challenges to renewable energy infrastructure developments\u201d.<\/p>\n The Guardian revealed recently<\/a> that the government\u2019s clean power 2030 target could be missed if it becomes too expensive. Miliband is about to launch the auction to buy renewable energy power, and will set a guaranteed price that will be paid to energy companies per megawatt hour. If the auction secures a lot of energy at long-term expensive prices, Miliband\u2019s promise to lower energy bills by \u00a3300 this parliament could be in jeopardy.<\/a><\/p>\n Windfarms can harm seabirds and marine mammals in the shallow waters and intertidal areas where they are located. The Berwick Bank windfarm in Scotland, for example, is predicted to kill 2,808 guillemots, 814 kittiwakes, 260 gannets, 154 razorbills and 65 puffins in its first year of operation, according to an analysis by the Scottish government. The number of birds killed by turbines, however, is tiny compared with<\/a> those killed by domestic cats and from flying into power lines.<\/p>\n skip past newsletter promotion<\/a><\/p>\n The planet’s most important stories.
