Abstract World wind power resources are abundant, but their utilization could be limited because wind fluctuates rather than providing steady power. We hypothesize that wind power output could be stabilized if wind generators were located in a meteorologically designed configuration and electrically connected. Based on 5 yr of wind data from 11 meteorological stations, distributed […]

Read MoreGrid-Connected Intermittent Renewables Are The Last To Be Stored
( Note – this article will shortly be published in the Elsevier International Journal of Renewable Energy which owns all rights.) Abstract When hydro-electric power systems became wide-spread, associated developments for energy storage, using pumped water, soon followed. Many other methods of storage have since been considered. Today’s interest in other renewables, notably wind energy […]

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 […]
Read MoreWhat happens to wind power when there is no wind? Why it makes perfect sense that old, polluting and inefficient coal fired power stations should be retained and receive a capacity payment
This note argues that environmentalists will have to recognise that part (and a small price) of the price we pay for creating significant additional capacity of intermittent / variable renewables is the continued existence of coal fired plant, operating at a very low capacity factor. (And of course it will make us less vulnerable to […]
Read MoreCarbon-free shipping – using renewables to create ammonia by electrolysis during peak periods to be used as shipping or aviation fuel
Carbon-free shipping. (Ed. – ammonia makes a very good aviation fuel) Ammonia (NH3) could be used as a carbon free fuel for shipping. It could be made from atmospheric nitrogen combined with renewable energy derived hydrogen. Ammonia’s hydrogen could react with oxygen to power engines, turbines or fuel cells, emitting N and H2O. Oxygen pre-separation […]
