ASHRAE - CELEBRATING 125 YEARS
and the utility industry discovered
the allure of combustion turbines
(CTs). The only problem with CTs is
that they are rated at 59°F (138.2°C)
and output de-rates dramatically on
hot summer days when it is needed
most. That generated a new application for cool TES. Chilled water or ice
can pre-cool the inlet combustion air
and regain the full output of the CT.
TC 6.9 sponsored programs on this
new opportunity and development of
the Combustion Turbine Inlet Air Cooling
Systems Design Guide.
In 1991, the Lincoln Electric System
(LES) in Lincoln, Nebraska, with
assistance from EPRI, installed the
first utility Turbine Inlet Cooling
(TIC) system to use TES (Photo 10). A
weekly-cycle ice harvester TES system was installed to pre-cool the CT
inlet air, recovering 20% of the lost,
hot weather output for 4 hours/day.
Other similar TES-TIC systems were
subsequently installed in Nebraska,
North Carolina, Wisconsin, and Saudi
Arabia during the 1990s; however, by
the late 1990s, CHW TES became the
dominant choice for TES-TIC, being
used in capacities of up to 700,000
ton-hrs (2462 MWh) at a single plant
in Saudi Arabia, for an increased hot
weather output of 30%.
In 2005, the Saudi Electricity
Company (SEC) in Riyadh, installed
a 192,800 ton-hr (678 MWh) dailycycle CHW TES system for TIC,
achieving a hot weather output
increase of 30% during six hours/
day. More and often larger CHW
TES-TIC installations have followed
in Saudi Arabia, Pennsylvania,
The LPD-Mag is the lowest
pressure drop Y-Strainer on the market,
upgraded with a Neodymium magnet. The
magnet protects your system from iron oxides
particles that can cause seal failures in pumps,
damaged boilers, chillers and heat exchangers.

Cool TES is still a viable (and growing) technology today. Early cool storage technology was inspired and significantly funded by the electric utility
