One of the most intractable energy problems in Europe is how to deal with the heating load of buildings, (11 EJ/y), which is the largest user of primary energy and is presently met largely with gas. This heat load will not go away due to the expense of insulating the legacy buildings beyond quite modest […]
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 MoreWhy was Dinorwig built? Load following, standby, fast reserve, pumped storage?
Roger, My own analysis has also shown that there is insufficient value in the difference between peak and off peak electricity prices to make energy storage economic. However, this may not be the only revenue stream for an energy storage system. Mechanisms that may provide greater return are as you say, within islanded communities (where […]
Read MoreSmart Metering Implementation Prospectus – The Transition – notes from an energy metering professional
1. CAPACITY IN WHICH I (Colin Boughton Smith) AM RESPONDING AND BACKGROUND I am the Managing Director of Energy Metering Technology Ltd (EMT), and am responding due to my passionate believe that automatic meter reading, and the awareness it brings to the consumer, is fundamental to achieve utility resource use efficiency. I have […]
Read More" Are Smart Meters Really That Smart?" who really benefits from smart metering?
On 3 October 2010 10:12, David Hirst .com <david@davidhirst.com> wrote: Good information is a Good Thing. 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 […]
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 […]

CAMPAIGN TO SAVE THE PULSED OUTPUT METER FOR THE SAKE OF UK PLC Summary: 50% of electricity and gas used in building is used in small quantities and metered through low volume non Half Hourly registering meters – as per your house which are read every 3 months roughtly, and hence are quarterly year metering .

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 […]

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 […]
