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 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 […]

Read MoreDecarbonising europe – European Climate found general consensus on one way forward for low carbon, affordable energy?
Dear all, I would like to introduce you to the analysis Dave mentions below and point everyone to the material at www.roadmap2050.eu . Just today more of the underlying material has been added to the site for download. The analysis examined plausible 80%-by-2050 decarbonisation pathways for Europe and then conducted a deep dive […]
Read MoreTiny Tech Steam Engines for Biomass to power
Dear Friends, Dave Andrews has suggested me to appraise you about my activity of steam engines and steam power plants which, I think, will play very vital role in shaping the economy of many developing countries in future. Just to get the idea of my steam engines, you can watch the following URL on […]
