But a CHP system like Enwave's,
which is connected to the grid and
had a total capacity of four megawatts,
is generally unattractive for
less-concentrated communities,
particularly in places with relatively
dirty electricity grids rather
than the clean grids of Toronto.
By dramatically increasing power
plant efficiency, CHP reduces fuel
costs, carbon emissions, and pollution.
CHP district energy systems
expand the potential thermal load,
reduce the requirement for capital
investment, and provide economies
of scale.
Conventional District
Cooling
As noted, Toronto's DLWC system is
extremely efficient, but DLWC has
a maximum capacity, like any utility
asset. Thus, in addition to the
DLWC, Enwave operates significant
conventional district cooling assets.
Enwave operates both the DLWC
and its conventional district cooling
assets in a synchronized manner to
optimize use of the more efficient
DLWC asset first, and then, when
DLWC reaches capacity, turns to
conventional district cooling.
In the absence of the availability
of DLWC in Toronto or elsewhere,
district cooling is an efficient way
to cool a network of buildings.
Central cooling plants house
large, efficient equipment that
produces chilled water that flows
through insulated piping into customer
buildings through a heat
exchanger, absorbing heat from the
building space.
Cooling typically creates 50 to 75
percent of peak electricity demand.
By aggregating cooling demand
among a network of buildings,
district cooling creates an economy
of scale that drives efficiency, balances
electric loads, and reduces
fuel costs.
District Heating
District heating, the original form
of district energy, is an efficient
way to heat a network of buildings.
Unlike CHP, district heating
produces only heat. Steam or hot
water produced at the central heating
plant is transmitted through
insulated thermal piping into customer
buildings, and the resulting
thermal energy is transferred to the
building's heating system.

among a network of buildings,
