5. Instantaneous response is necessary and is
obtained by ‘Frequency Sensitive Switching’
Of 2GW of Large Industries e.g. Steelworks
Some large storage devices
Some 2GW of ‘Spinning reserve’ generators

6. ‘PEAK DEMANDS’ ARE A MAJOR PROBLEM FOR ELECTRICITY SUPPLY
So that UK has to keep over 50% Capacity
& Distribution facilities waiting on a hierarchy of ‘standby’ to meet it.
Giving rise to Some 7Million tonnes of extra emissions of CO2 a year.
‘Peak demand’ could easily be brought under control by Dynamic Demand Control
But, as yet, there are no incentives to reducing this waste.
We do not face the real price of ‘real time’ production.
If we were to then we would certainly adjust our demand accordingly
Dynamic Demand Control would serve 2 Functions:
To provide a dynamic response to help eliminate the instantaneous changes
of duty demanded of the supply grid that currently in UK requires some
2000MW of immediately available ‘Spinning reserve’ generator plant.
Causing over 1Million tonnes of ‘avoidable’ CO2 emissions a year.
To give users dynamic load control enabling them to minimise the
‘Peaks and times’ in their Demand Patterns and thereby in turn to minimise
the total generator and distribution facilities required.
An important further benefit of Dynamic Demand Control is that it would better facilitate the ‘acceptance onto the grid’ of local ‘micro-generated’ renewable power.
This is at present an unresolved problem for The UK

8. In The UK At least 2000MW
of ‘Low efficiency Generation’ plant
Is kept in ‘Spinning Reserve’
France similarly has 5000MW
The EU total must be enormous.

9. Innovative Tariffs are essential to bring about a correction to this
Smart Meters
Remote
Monitoring
Energy End Use and ESCO directive
2006/32/EC May 2008 implementation
Of The EUROPEAN PARLIAMENT
Article 13 Covers a requirement for
more accurate and informative billing.
Innovative Tariffs are essential to bring about a correction to this
‘Gross inefficiency’ of our major energy supply system
A Tariff that gave a ‘properly priced’ least cost ration of units first
with unit charges increasing according to production costs thereafter
Would, not only correct the inefficiency and resulting emissions but, also
Help to address the ‘Fuel Poverty’ problem for lower income citizens.

10. ‘Smart’ building systems With ‘Smart metering’ for
‘Demand Response’ and
‘Peak Demand’ control
Dynamic response on Appliances alone has potential to eliminate need for ‘Spinning Reserve generators’

11. Conclusion:
Dynamic Demand Control could help to eliminate Peak Demands from Electricity Supplies and thereby quickly bring a major contribution to EU Policy, on Energy useage and Climate changing Carbon emissions, at an economic cost below almost any other method
The Technology for DDC is developed and, after agreement on content and protocols, would be ready for use.
Appropriate Innovation of present-day tariffs is essential
to make best use of DDC,
Once implemented; Building developers & designers will take advantage and so deliver more sustainable buildings. And users & operators of ALL buildings, both New and Existing, will be able to achieve markedly better ‘Operational Performance’.
