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 […]
Read MoreThe 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 […]
Read MoreWrong-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 […]
Read MoreAspects 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 […]

Read MoreDidcot A Coal Fired Power Station – and potential impact of large wind energy on maintenance costs of two shifting power stations
Note: Some notes have been added, via the comment field which originate from the Claverton emails, from authoritative persons, which inter alia indicate that the maintenance and operating costs for a plant such as this are slightly less than 0.4p/kWh. Background and Location Didcot A is was built as a coal fired steam power station […]
