Demand manage

Are large thermal stores and Combined Heat and Power District Heating (CHP) with District Heating (DH) pipes to deliver heat to buildings is more likely to be a better solution to de carbonising the building heating sector than relying on large-scale electricity storage of renewable or nuclear electricity (the “all electric solution”) delivered to buildings via cable?

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 levels and the new build rate of new low energy buildings is too low to have any significant im... »

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 ... »

Why 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 electricity is typically diesel generated), reducing peaks (... »

Smart Metering Implementation Prospectus – The Transition – notes from an energy metering professional

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.

Aspects of the dynamics of the UK National Grid, how the grid frequency varies – and the role of ENF in forensic science

Dave Andrews August 20, 2010 Demand manage, Electricity/Power Grids, Grid control 2

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 machines that are connected to the Grid are locked in to ... »

( 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.

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 from renewable energy sources by 2020. After 2020, a higher pro... »
