Common Methodology Group Work
PRESENTED BY OLIVER DAY
Common Distribution Charging Methodology
Impact Analysis
10 September 2009
Caveats…
• Based on individual DNO averages• Need to consider your typical usage
• Common model – DNO specific inputs• Different end user behaviour• Different costs
• Current DNO models may be very different, resulting in sometimes opposing starting positions
