Read MoreEffect of brutal cutoff of wind capacity – Spanish Wind ramping, intermittency back up
http://www.carboncommentary.com/2009/11/15/853 Spain’s variable wind and stable electricity networks Sunday 15 November 2009 in uncategorized by Chris Goodall One of the frequent criticisms of wind energy is that national distribution systems (‘the grid’) cannot cope with large number of turbines because of the variability and unpredictability of their output. Grids need to match supply and demand […]
Read MoreIs nuclear power flexible, does it have load following capability?
Some Notes on the Flexibility of Nuclear Units What is “Flexibility”? What does “flexibility” mean for a generating technology? I guess that most people would think about the ability to increase or decrease active power output (Megawatts) either on instruction, or automatically, in order to help balance generation and demand on the system. But the […]
Read MoreWill 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 […]
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 […]

The Conference on Independent Power Generation will be held at the NEC Birmingham, 8th – 10th June 2010. IP&EE – Independent Power & Energy Europe – is the essential biannual event for the Independent European Energy Sector. The Show provides an ideal platform for players in the energy industry to showcase the latest cutting-edge technology […]
Read MoreElectric power transmission costs per kWh transmission / National Grid in the UK (note this excludes distribution costs)
Info from National Grid on Capex of UK Transmission system ( this would appear to confirm that transmission charges are based on replacement costs, not written down / depreciated. I’m not an accountant / economist but if you divide the £11.5b over say 30 years repayment and add in the 4.5% and divide by kWh […]
Read MoreThe CEGB (Central Electricity Generating Board) were not blinkered and recognised that wind had a capacity credit value
We weren’t blinkered in the CEGB. We were well aware that wind energy CAN be credited with firm capacity [see Swift-Hook, D. T., 1987 “Firm power from the wind” Wind Energy Conversion, Ed. J. M. Galt, (MEP : London) p. 33] and that the cost of off-setting the variability of wind is modest, see […]

The declaration: 1. The Ministers of the North Seas Countries: Belgium, Denmark, France, Germany, Ireland, Luxembourg, the Netherlands, Sweden and the United Kingdom Considering, 2. The crucial role which offshore wind energy is bound to play in order for Europe to meet the EU’s 20-20-20 targets. The major part of offshore wind energy development in […]
Read MoreThe costs of variability due to the presence of large quantities of intermittent/variable wind energy on the UK national grid.
Managing Variability – A report to WWF-UK, RSPB, Greenpeace UK and Friends of the Earth EWNI SUMMARY In order to comply with legislation from the European Union, the UK’s renewable energy target (to produce 15% of final energy consumption from renewable sources by 2020) may require between 35 and 40% of our electricity to come […]
