A reliable foundation: Coal, natural gas and transmission
Associated’s coal and natural gas generating fleet provides a foundation for member reliability unmatched by
intermittent generation technologies. Dispatchable, base load coal power operates when members need it 24/7/365,
while quick-start natural gas plants provide base load and peak power. Working together for members, the coal and
natural gas fleet generated record output during 2022, delivered across an extensive and resilient transmission system.

Challenged by increasing influxes of inter-
mittent power that appear on the system and
disappear just as quickly, the transmission
assets of Associated and its six member-owner
transmission cooperatives have maintained ex-
ceptional reliability. Transmission investments of
$420 million are planned to renew, upgrade and
add to the 10,000-plus mile network of high-volt-
age infrastructure. The reliability and resiliency
of the system will remain a strength and focus
as surrounding systems retire assets and new
renewable generation projects go online.
