National Grid

Chris Ruane: To ask the Secretary of State for Energy and Climate Change how many reported breakdowns there were in the national grid network in each year for which figures are available. [263103]

Mr. Mike O'Brien: The following table shows the number of unplanned outages of the GB electricity transmission system which led to customer disconnection between 1991-92 and 2007-08. The table also shows the amount of power in megawatt hours (MWh) lost in each of those years. The data are taken from National Grid's annual transmission performance reports.

National Grid: Weather

Graham Stringer: To ask the Secretary of State for Energy and Climate Change if he will bring forward proposals to protect the national grid from extreme solar weather events. [267658]

Mr. Mike O'Brien [holding answer 30 March 2009]: National Grid (NGET) is aware of the phenomena of extreme solar weather events and began preparations for the next peak in 2011-12 some years ago. NGET has procedures in place to improve the resilience of the
20 Apr 2009 : Column 317W
network which include putting their field force on standby and ensuring that enough reactive power is available (a technical service provided by generators which helps manage voltage fluctuations—a possible consequence of both a conventional and severe solar storm).

The electricity networks are designed to provide a level of resilience that would cope with incidents that are potentially more severe than those that may be caused by a solar flare. Similarly, Government emergency planning arrangements are in place and tested to be able to cope with a complete shutdown of the electricity network. There is therefore no requirement for additional resilience or emergency response measures to deal with any potential disruption due specifically to a solar flare.

Natural Gas

Mr. Crabb: To ask the Secretary of State for Energy and Climate Change what assessment he has made of the effect of levels of Crown Estate rents on trends in investment in offshore gas storage infrastructure projects. [266864]

Mr. Mike O'Brien [holding answer 26 March 2009]: None. The cost of the lease will be a matter for negotiation between the Crown Estate, acting in accordance with its statutory framework, and the developer.

Natural Gas: Storage

Mrs. Gillan: To ask the Secretary of State for Energy and Climate Change what estimate he has made of the levels of employment that would result from the liquefied natural gas facility on Anglesey and the gas storage facility at Preesall coming on-stream. [268594]

Mr. Mike O'Brien [holding answer 2 April 2009]: I have not made any such assessment. However, the facilities on Anglesey and at Preesall would make a valuable contribution to the security of the UK's gas supplies if they were to come forward.

Mrs. Gillan: To ask the Secretary of State for Energy and Climate Change what assessment he has made of the changes in the ability to import and store gas that would result from the liquefied natural gas facility on Anglesey combined with the proposed gas storage facility at Preesall, Lancashire coming on stream. [268595]

Mr. Mike O'Brien [holding answer 2 April 2009]: The Preesall gas storage facility would potentially provide approximately one billion cubic meters of gas storage capacity, making a valuable contribution to UK gas supplies. The proposed liquefied natural gas (LNG) facility on Anglesey would provide a welcome increase in the amount and diversity of the UK's gas import capacity.

Mrs. Gillan: To ask the Secretary of State for Energy and Climate Change what assessment he has made of the effects of the current level of availability of finance on the delivery of new gas storage projects. [268596]

Mr. Mike O'Brien [holding answer 2 April 2009]: The current financial climate makes raising funding for gas storage developments, like other projects, more difficult
20 Apr 2009 : Column 318W
for some smaller developers but this is less of an issue for the larger ones. We are working closely with the industry to ensure that they make the most of alternative funding sources including the European Investment Bank.
