Revolt Newsletter 94

01/08/2001


Items on health issues are building up and will probably appear in news95.

1. The Embedded Generation Working Group (EGWG) at DTI has produced a report on generating your own electricity. Domestic micro CHP is on the agenda. Quotes in the DEFRA publication Energy & Environmental Management July/Aug 2001 say that over half Britain's Kyoto requirements could be met if every home with a boiler converted to domestic CHP, and that 16 million households could save some 4 billion pounds per annum. That's 250 pounds per house. However, there are still "significant regulatory barriers" which government CHP policy is to address and an Ofgem team is to review over a schedule up to 2005. Last year a handful of products were installed in homes for testing. This coming winter several hundred will be installed and tested for impact on the grid. Deals could be on offer "by mid 1992". Micro CHP could be in 2 million homes by 2010 and eventually in 12 million homes in the UK. The report can be downloaded from http://www.dti.gov.uk/energy/egwg/index.htm . See also www.chpclub.com .

2. NGC's booklet on the Lackenby-Picton-Shipton line are up to issue 4 of Feb 01, and the booklet on the Newby to Nunthorpe underground cable is up to issue 4 of Sep 00. They are available from NGC on 0800 833490.

3. A few weeks ago my nearly-4-year old granddaughter asked about our Revolt car sticker. After a brief explanation she replied that if the pylons went up we should get the Big Bad Wolf to come and blow them all down.

4. Lots of news from the CHPA bulletin CoGen #24, June 2001. In the following, MWe, MWh and MWc mean MegaWatts of power for electricity, heat or cooling, respectively. Likewise kWe etc. 

(a) The Microturbine is here! County Hall, Durham, is trialling the 28kWe/50kWh MiniGen CHP Advantica unit. It looks like a domestic boiler, but slightly larger, neat and clean. It can be installed singly or in multi-unit sets up to 500kWe in offices, leisure centres,, schools, hotels etc. The 28kWe unit is estimated to save 5,000 pounds per year with typical payback period 3 to 5 years.

(b) Trigeneration is catching on. That's electricity, heat and cooling. Gateshead's Baltic Flour Mills is being redeveloped as an arts centre, with a 400kWe/520kWh/350kWc CHP system supplying its entire heat, power and cooling needs. Overall efficiency 72% is much better than any power station.

 Woking town centre's district energy station has a 1.35MWe CHP unit incorporating a 1.4MWc absorption chiller; it has its own 11kV private wires laid alongside heating and cooling mains, serving a hotel, council offices, a leisure centre, night club and car park.

A 395kWe unit supplies Air Products' large 800-staff office block with all its heating and summer cooling, and 40% of its daytime electricity, removing an old Freon (now banned) cooling system and saving 2,700 tonnes per annum CO2 emissions, all at no capital cost to Air Products.

Telehouse IT switching centres at Hemel Hempstead and Bristol are to have trigen systems; multi-unit systems contribute to the vital security and reliability of power supplies; both sites will use 6 x 600kWe and 4 x 1 MWe units achieving 20% CO2 reductions and avoiding standby generation and electric air conditioning.

London's Barbican Centre has replaced 6 obsolete refrigeration chillers and removed 2 wet cooling towers, by installing a trigen CHP system with 2 x 5.6MWc absorption chillers.

(c) In spite of many excellent CHP developments, government CHP targets of 10 GWe by 2010 are being hampered by regulation policy, according to the key DTI Energy Paper 68, which says new measures will be needed.
Two 70MWe CHP schemes have been put on hold by British Sugar. The main problem is in the New Electricity Trading Arrangements (NETA) which took effect at the end of March, which handicaps small, distributed generators.
Ofgem is to review NETA. Environment Minister Michael Meacher has stressed the need to address the concerns of CHP thoroughly.

(d) John Prescott has launched a 50 million pounds government scheme "Community Energy" to promote community heating and CHP. The CHPA estimate a million homes could benefit.

5. NFU solicitors are taking up the case of NGC conduct and entry on to land at Pintail Nest (revolt news90.5 and 92.3). NGC's General Counsel and Company Secretary Alison Kay replied 23.7.01 to my emails 5.7.01 and 11.7.01. They claim, and on checking we accept, that the police did not ask NGC personnel "to leave" the farm, but asked "if they would leave" when asked by the landowner. A slight but important difference, as NGC did not then "disobey" the police. The main point remains, that NGC were not entitled to take access without the landowner's agreement, or a court order in lieu of agreement, though Alison Kay is quibbling. All our legal advice is clear, NGC have no such right and if they want to enter against the landowner's refusal they must go to court. Alison Kay says they are prepared to go to court if necessary. The plot continues ...

6. FMD restrictions have been tightened in the "Biosecurity Intensification Area" which includes the whole line route from near Ellerbeck to York. The northern part of the route has had several outbreaks and continues to be a Footpath Exclusion Area with restrictions. It is hard to see NGC ancillary work for the line resuming in the coming months.
