Jointly-Owned Facilities [Abstract] |
Jointly-Owned Facilities [Text Block] | JOINTLY-OWNED FACILITIES Following are our investments in jointly-owned facilities and the related ownership percentages as of December 31, 2012:
Regulated Utility Plant | Plant in Service | Accumulated Depreciation | Construction Work in Progress | % Ownership
Millions |  |  |  |
Boswell Unit 4 |  | $413.1 |  |  | $188.1 |  |  | $25.0 |  | 80
CapX2020 | 22.8 |  | 0.4 |  | 25.4 |  | 9.3 - 14.7
Total |  | $435.9 |  |  | $188.5 |  |  | $50.4 |  |
We own 80 percent of the 585 MW Boswell Unit 4. While we operate the plant, certain decisions about the operations of Boswell Unit 4 are subject to the oversight of a committee on which we and WPPI Energy, the owner of the remaining 20 percent of Boswell Unit 4, have equal representation and voting rights. Each of us must provide our own financing and is obligated to pay our ownership share of operating costs. Our share of direct operating expenses of Boswell Unit 4 is included in operating expense on our Consolidated Statement of Income. We are a participant in the CapX2020 initiative to ensure reliable electric transmission and distribution in the region surrounding our rate-regulated operations in Minnesota, along with other electric cooperatives, municipals, and investor-owned utilities. We are currently participating in three CapX2020 projects with varying ownership percentages.
