Yet another poor field report from small, often roof-top, wind turbine installations in the UK.   Conclusion: Wind turbines need wind.  (Doh!)  The full PDF report is available on the Encraft website link.

Updated: UK Wind Industry Claims Micro-Wind is Working - BusinessGreen - 13 Jan 09

"The study from renewables consultancy Encraft assessed electricity output from 26 building-mounted wind turbines and found that on average they provided only five to 10 per cent of the energy claimed by manufacturers. The worst performer generated just 41 watt-hours a day, not even providing enough electricity to power the turbine's own electronics.  Matthew Rhodes, managing director of Encraft, told The Telegraph that there was a need for wind turbine manufacturers to provide clearer information on which sites are suitable for on-site turbines."

My recent reference of a $2,600 / kW figure for large scale wind came from an NREL source giving a recent figure they'd been told.  This new report has a more systemic analysis of the installed cost of wind systems albeit from an earlier time frame.  Suffice it to say that wind turbine prices are somewhat dynamic and that the recent chaos in the financial markets generating reduced demand, changes in material prices and reduced waiting times for turbines may also be having a significant downward pressure on turbine pricing.

"Average cost for new wind capacity in 2007 was per $1,710 per KW, according to the Annual Report on Wind Power 2007 [PDF]. Some of the largest new wind farms had costs as low as $1,240 per KW, while the smallest ones tallied costs as high as $2,600 per KW.  Further, large new wind farms got more use from each KW than small ones -- as much 40 percent capacity utilization for big farms on the best sites vs. a 33 percent to 35 percent average. Since capital costs and capacity utilization overwhelmingly determine wind costs, big wind is simply less expensive than small wind."


And on the nuclear front, new reports of delays from the AREVA-Siemens project in Finland.  Now they are up to being about three years behind schedule and about 50% over budget.  No word of additional increases in costs that will go along with the latest delay but there is a new legal effort by the plant construction group to get out of their fixed-price turnkey contract and shift some of the additional expenses to the Finnish utility, TVO.  TVO is none too keen on AREVA-Siemens either and has filed its own grievances over the construction delays.

Finland Nuclear Plant Delayed to Mid-2012 - TVO - Reuters - 13 Jan 09

"A nuclear power plant under construction by the Franco-German Areva-Siemens consortium in Finland will be further delayed to mid-2012, utility TVO said on Tuesday."  "The 1,600 MW reactor -- the first to be constructed in Western Europe for more than a decade -- has been delayed for several times from its initial start-up target of 2009."

"TVO said details of the forthcoming process would be kept private but stuck to its guns: 'TVO has a fixed-price, turnkey contract with Areva-Siemens for the construction of the Olkiluoto 3 unit.' Areva said on 19 December that some delays were 'caused by TVO.'   At the end of 2003, TVO signed a €3 billion deal with Areva-Siemens for the construction of an EPR nuclear power unit at Olkiluoto."

Nuclear Power Construction Delays to Arbitration - YLE - 31 Dec 08

"TVO said on Wednesday that it been informed by the International Chamber of Commerce (ICC) that the plant supplier, consortium AREVA-Siemens, has filed the request for arbitration.  The request relates to a claim presented previously by the consortium to TVO, which TVO has studied and said it found to be without merit. TVO has earlier claimed for compensation from the plant supplier for losses and costs incurred due to the delay to the project.  Based on the ICC rules, and on the plant supply contract, arbitration is a private process and not to be commented on in public."
