Nobody doubts that, for some people and organisations, improved information about their electricity (and even gas and water) consumption and its costs could provoke some behaviour change, or trigger energy saving investments. Indeed, current UK laws assume this is […]
German government major conclusions of a review of energy policy in its Energiekonzept.
On 14 September 2010 09:42, Matt Phillips In case you have not studied the German Energiekonzept document, below are some informal notes on what it says. Last week the German government released its major conclusions of a review of energy policy in its Energiekonzept. If your German is up to scratch, here it is: http://www.bmu.de/files/pdfs/allgemein/application/pdf/entw_energiekonzept_kf.pdf […]
Critique / comparison of bio fuels / jatropha / with other energy options – wind etc
I think Haiti needs Jatophra like it needs another earthquake I’m sure they would much rather have a little help to rebuild their lives, housing and infrastructure;- notably absent from all the international organisations and charities. They are more likely to need Food. Food and Water? – a seawater Greenhouse ?. For Energy – a […]
Suppressed Government peak oil dossier – anyone got a copy please?
Dear Clavertonians, Received this from Mobbsey the other week (see below)…wondered if any of you could locate a “leak” of this particular British Government document to share with the rest of us even though David MacKay couldn’t get his paws on one…we owe it to our nation to tell the truth…can’t remember how to conjugate […]
Will wind farms pick up the tab for new nuclear? Wind farm developers fear National Grid proposals designed to accommodate nuclear power plants will lead to a huge increase in backup costs
David Hirst Comments. Chris, You are quite right to separate the issues of immediate loss of generation, which needs to be covered by frequency response, and the longer term periods of scarcity that need to be covered by “reserve”. If the reports are true What NGC seems to be seeking to cover here is the […]
Smart Meters — Smart Savings or Smart Profits ? Are the Costs & Benefits Fairly Apportioned ?

DECC/Ofgem E-Serve are working through activities and consultations with the aim of defining the implementation programme; a programme that will shape the type and scope of services for energy and carbon […]
The value of electricity storage to the UK power system
Dave, I’ve got around to looking at the value of storage and have prepared a simple model to assess this for the GB system, copy attached (in Excel 2007 containing a couple of macos). I’ve taken some sample days of historic price profiles from the www.bmreports.com website – two for each month of […]
Wrong-Footing the CRC – Carbon Reduction Commitment DECC
The Carbon Reduction Commitment or CRC came into effect this April and appears to have taken many by sur-prise. One newspaper suggested that as many as 43% of potential CRC partici-pants had never heard of it. The timetable for the scheme is such that those organisations claiming igno-rance will fail to register by the end […]
Aspects of the dynamics of the UK National Grid, how the grid frequency varies – and the role of ENF in forensic science
The system frequency target is normally set at 50.00 Hz. Frequency changes as the balance between demand and generation alters. The Grid controller attempts to balance the two by instructing the generators, but there is a range of frequencies between which no instructions will be issued, say 49.95 to 50.05 Hz. All generators and synchronous […]
