Our current assessment (updated in June
2013) is that the risks to electricity
security of supply will increase in the next
five winters. In particular, we expect that
electricity de-rated capacity margins will
decrease significantly from the current
historically high levels.
The WATTSTOR substantially maximised the self-consumption of
solar PV generation and minimised the import of grid electricity
at the test site during the monitoring period 1st – 31st July 2013.
The daily electricity import from the utility company averaged 3.5
kWh (costing 53p at a 15p tariff rate) during July 2013 and on two
very sunny days was less than 1 kWh (15p).
The electricity import (using utility company data) in July 2012
was 534 kWh with solar PV only. In July 2013 with a WATTSTOR
fitted this was 107.9 kWh. This represents an 80% reduction in
utility company import to the home during summer periods of
high solar generation.
• Energy prices will continue to rise at above
• Security of supply will decrease over the next
• Consider local (renewable) generation
• Actively manage your energy usage
• This is an opportunity as well as a threat
• Smart Cornwall Programme can help
