A defense bill signed by President Barack Obama includes more than $21 million for military construction in Cheyenne.
F.E. Warren Air Force Base would get $12.6 million to replace an aging centralized heating plant. The Wyoming Army National Guard would get $8.9 million for a readiness center.
Warren officials estimate the heating project would pay for itself in 7 1/2 years through energy savings once the conversion is completed. The changeover is expected to take two years.
The existing system would be replaced by individual systems for each building.
