Xcel Energy is rebuilding approximately 25 miles of 115-kilovolt (kV) transmission lines connecting the Palmer Lake, Castle Rock, Crowfoot Valley, Happy Canyon, and Daniels Park substations in Douglas County. This includes work on the lines that go through the City of Castle Pines. The transmission lines were originally built in the 1950s. Due to natural weathering and the overall age of structures, they have reached the end of their useful life and must be replaced. New infrastructure will improve electric service reliability to homes and businesses in the region, proactively reduce the risk of damage from wildfire and help meet the growing energy needs of homes and businesses for years to come.
Construction will take place within Xcel Energy’s existing right-of-way. The project will be completed in several phases. The first phase, between the Palmer Lake and Castle Rock substations was completed in Spring of 2024. The second phase, which includes rebuilding the line between the Happy Canyon and Daniels Park substations will begin in October 2024. Survey and staking work for segments between the Happy Canyon and Castle Rock substations took place in summer 2024 with construction work beginning in early 2025. All Work should be completed by the end of 2025.
