Our cities are growing, placing stress on our energy network. More buildings mean more PEAK power demand requiring new power stations. But PEAK power is rarely required. What if we could store it economically?

‘Cooling with ice reduces electrical demand’

A presentation by

3. 236 buildings with more than 20 stories
planned for London require cooling.
Our cities are growing....

4. ...and they will all use energy, at the
same time.
This places stress on our energy network.

5. Currently, most of our energy is stored as
fossil fuels.

6. Power stations must produce enough
energy to meet variable demands

10. CALMAC integrates energy storage as ice
tanks into the cooling systems of
buildings.

11. Buildings require
cooling to provide
comfort by removing
the heat generated
by lights, people,
computers and the
sun.

12. Electricity is used to
power equipment to
cool the building.

13. At night, occupants
leave the building
negating the need
for cooling

14. The CALMAC system
takes advantage of
low energy demand
to make ice which is
stored in an array of
Ice Tanks.

15. Peak electrical
demand is then
reduced by using the
energy stored as ice
to cool the building.
Which also reduces
the electrical
availability charges
for the building.

16. Infrastructure and
business benefits
from reduced costs
plus there is no need
to ‘switch anything
off’ and occupants
continue to be
comfortable and
productive....

17. .... they also save
money by utilizing
more favorable ‘off
peak and other
incentive’ Tariffs.
Energy consumption
is reduced when it’s
most expensive and
polluting.

18. In the future when there will be many
more renewable energy generating
technologies such as wind turbines.

19. But when the wind stops, we need to be
able to prevent blackouts.

20. The current option is to use stored fossil
fuel to meet demand and keep the lights
on...

21. ...the alternative is to use stored energy
to overcome the fluctuations in power
supply from renewables.

22. The CALMAC solution reduces the need
to use dirty, carbon intensive ‘peaking
generators’ and ensures that energy
generated by renewables is captured.

24. CALMAC ice tanks have been installed in 4,000 projects
world wide since 1979. Shifting 6 GW hrs and reducing peak
demand by 1 GW.
1% of installations currently in the UK shifting 60 MWhrs and
reducing peak by 10MW.

26. Business wins – comfortable buildings
reduced costs

27. Environment wins – less CO2

28. Society wins –reduced electrical
infrastructure
