Load management

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... »

Effect 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 ... »

Is 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 issues are “How much?”; “How... »

Wednesday 29 September 2010, Energy Institute, London The implementation of Smart Meters in the UK has major implications for business and the public sector. DECC/Ofgem E-Serve are working through activities and consultations with the aim of defining the implementation programme; a programme that will shape the type and scope of services for energy and carbon management which will be available to ... »

The value of electricity storage to the UK power system

Dave Andrews August 22, 2010 Load management, Storage 1

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 the past year to represent business and non business days.  The first thing... »
