https://mail.google.com/mail/?shva=1#inbox/1384c714ccc80b76 takes you to mail with file attached… ——– Original Message ——- I am wondering if you all might be interested in a proposal I am pushing in Australia that might also be relevant to other places with renewable energy resources in remote areas such as in North Africa, the Middle East, desert areas in China […]

Read MoreAre 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 […]
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 MoreEffect of a step change in wind output or load on in grid frequency and control mechanisms
Fred, The frequency is system-wide. That is, all parts of an A/C system will have the same frequency. Any change in frequency is a reflection of a change in the balance between supply and demand. So a drop in frequency is a reflection either of a loss of generation, or an increase in demand. Actual […]
Read MoreWater metering
Companies like meteringtech.com have “self learning” software (ours is called TRACKER analysis module of DYNAMAT) that will self learn a profile of consumption from high frequency interval data (AMR) and continuously compares current consumption with the self learned target, alarming if excessive consumption is detected. We can home in on the “night line” hours as […]
Read MoreReal Time Home Energy Monitoring using low cost clip on meters – the Smart alternative to Smart Meters
Set out below are some of features of the Real Time monitoring that we are doing with the new breed of low cost clip on meters – we are working with the Current Cost meters but the principle applies to many of these meters. Current Cost meters costing ~£45-60. We currently have a free application […]

Jeremy Harrison runs micro CHP information website (www.microchap.info) which gives quite a bit of information on engines and other prime mover technologies for micro and mini CHP. You will also find links to preview his book on micro CHP or click here: http://www.blurb.com/books/1478310 Kind regards Jeremy Harrison Technology Consultant Energy Infrastructure & End Use Many […]
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 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 […]
