Supplementary memorandum by Mr Derek Birkett
As part of my submission for the Call for Evidence
into the Economics of Renewable Energy I would wish to include
the following addendum:
6A. An alternative fast acting response can
be obtained from demand management. However, this option is not
straightforward and could only present a limited solution. Aside
from industrial use, any commercial/domestic load demand is largely
constrained to water and space heating on dedicated circuits.
In summer conditions this response would be minimal at the very
time when the Grid system would be most vulnerable to problems
of intermittence. There needs to be incentive with both tariff
and installation measures, administered by distribution utilities
and whose costs would be correctly categorised as balancing services
for the national Grid, eventually to be borne by the consumer.
11A. Recent enquiry into planned reactor
size has established an electrical power output of approximately
1600MW for new construction. This compares to the existing single
example of Sizewell with power output of 1320MW. I believe system
design currently accepts 1250MW for any single loss event.
I would be grateful if this clarification could
be included with my submission.
