Economic employment and environmental benefits from Industrial demand-side management

Objetivo

To evaluate the costs benefits and effectiveness of a range of industrial demand-side measures. To establish the potential for approaches elsewhere and assess the potential economic and employment benefits.
Sustainable reduction in load on the network;
Sustainable reduction in CO2 emissions;
An evaluation of programme costs versus the avoided costs of reinforcement;
Effectiveness of contract energy management as a demand-side management measure;
Direct cost benefit to large industrial customers.
As an electricity company, Manweb cannot justify demand-side measure on the basis of avoided costs of generation plant. This financial justification exists in Crewe but other factors are also important.

Crewe has a population of 103,000 and has been historically dominated by two employers:

British Rail Engineering Ltd (BREL),railway rolling stock manufacturer and repairer;

Rolls Royce Motors Ltd, manufacturers of luxury motor cars.

Both these large employers have been reducing the number of workers they employ and unemployment is now at 10%. Great importance is therefore placed on preserving employment amongst other industrial companies in the town and in creating new jobs by attracting inward investment.

Recent infrastructure development has created a new business and industrial park, but such are the present loads on the network in the area that Manweb's ability to add incremented demand to the system is limited. A programme of demand-side measures, aimed at the other industrial users adjacent to the new industrial park, could therefore
free-up capacity for expansion and reduce the cost base of local employers.

The area of the Crewe PowerSave project is served by a 33 kV ring main, rated at 20 MVA, but presently loaded at 25-26 MVA, and with immediate demands for new load of 880 kVA. The main is fed from both ends enabling safe operation up to 28-30 MVA in good conditions, but an unplanned outage, or part of the system tripping-out would require almost immediate load shedding, with its consequent problems for industrial users.

Load reduction through demand-side management would void or delay the installation of a new 33 kV transformer and other new cabling to create an additional ring main in the area. It would also free-up capacity for new businesses to become established on the industrial and business park, helping job creation, as well as reducing the energy costs of existing industrial customers.

It is proposed to implement measures primarily through third party finance contracts (Contract Energy Management).
