Energy: Wind Generation

Volume 711: debated on Monday 8 June 2009


Asked by

To ask Her Majesty's Government what is the forecast capacity of wind-powered electricity generators from Wales expected to be incorporated into the National Grid; and which individual proposals in which locations constitute that capacity. [HL3109]

Wales currently has 420MW of operational wind energy: 360MW onshore at various locations as well as 60MW offshore at North Hoyle. 90MW is under construction at Rhyl Flats and the 750MW Gwynt-y-Mor offshore project was consented in December 2008. These offshore wind farms are all situated off the north Wales coast.

The Government estimate that meeting our share of the EU 2020 target might require up to 14GW of onshore wind and up to 14GW of offshore wind generation—a proportion of which will be in Wales. The Welsh Assembly Government's 2008 Renewable Energy Route Map For Wales at desh/2008/renewable/routemape.pdf?lang=en stated that if all potential projects were to go ahead in full, wind farms within the TAN 8 planning/policy/tans/tan8/?lang=en strategic search areas could produce up to 2,500MW of generation capacity.

We are currently aware of around 2,000MW of possible onshore wind energy projects in Wales at various stages in the planning system. These include the projects listed in the table below, which are with the Secretary of State for approval under Section 36 of the Electricity Act 1989. In addition there will also be other current applications under the Town and Country Planning Act 1990 which will be dealt with by the relevant local planning authorities in Wales.

Asked by

To ask Her Majesty's Government what was the contribution to the National Grid made by wind power during the coldest days between November 2008 and March 2009. [HL3408]

Electricity supply data are not available on a daily basis. Data for electricity supplied by wind generation (major power producers only) to the public supply system for the months of November 2008 to February 2009 can be found in the table below. Data for March 2009 will be available on 28 May 2009.

Asked by

To ask Her Majesty's Government what is their projection of the cost of building all further wind turbines required to enable them to meet their 2020 renewable energy targets, including additional transmission lines. [HL3409]

The UK Renewable Energy Strategy consultation document http://decc. mix/renewables/res/res.aspx set out a central scenario for deployment of renewable energy needed to meet the UK's share of the EU renewable energy target.

The resource cost (the cost of the renewable technologies less the cost of conventional generation and carbon allowances) of increasing the level of renewable electricity to meet that scenario, including additional costs to grid infrastructure, was estimated to be in the region of £2.2 billion to £2.6 billion pa in 2020, £33 billion to £37 billion cumulative to 2030. This cost relates to the impact on the electricity market of all renewable electricity technologies that will be incentivised through the renewables obligation (RO) to contribute to the achievement of the 2020 renewables target. There are no estimates of the cost of the RO for individual technologies.
