Title: CENTRE FOR SUSTAINABLE POWER DISTRIBUTION


1
CENTRE FOR SUSTAINABLE POWER DISTRIBUTION
This is widely recognised as a Centre of research
excellence within the area of electrical power
energy systems.

2
Continued/---
  • The Centre has substantial co-operative research
    grants and contracts from the Research Councils,
    manufacturing and the utilities and welcomes many
    Visiting Fellows from overseas institutions and
    companies.
  • Members of the Centre are heavily involved in the
    EPSRCs Supergen programmes dealing with issues
    of sustainable power generation and supply.

gt Development of network charging methodologies
for use of Western Power Distribution Network
19
Problems and Objectives
  • Distribution Reinforce Model is economically
    inefficient - Postage stamp2. DRM does not
    acknowledge the benefit of embedded generators
    3. Introducing more efficient distance based
    charging methodology - Investment Cost
    Related Pricing (ICRP)

20
Assessing the benefits of moving to an
economically efficient distribution charging
compared to the existing approach based on the
Distribution Reinforcement Model ----- DRM-----
Investment Cost Related Pricing ----- Long-run
Incremental Cost Pricing
gt Cost-benefit analysis of network charging
methodologies
