DP&L has undivided ownership interests in five coal-fired electric generating facilities, various peaking facilities and numerous transmission facilities with certain other Ohio utilities.   Certain expenses, primarily fuel costs for the generating units, are allocated to the owners based on their energy usage.  The remaining expenses, investments in fuel inventory, plant materials and operating supplies, and capital additions are allocated to the owners in accordance with their respective ownership interests.  At March 31, 2015, DP&L had $24.0 million of construction work in process at such jointly owned facilities.  DP&L’s share of the operating cost of such facilities is included within the corresponding line in the Condensed Consolidated Statements of Operations and DP&L’s share of the investment in the facilities is included within Total net property, plant and equipment in the Condensed Consolidated Balance Sheets.  Each joint owner provides their own financing for their share of the operations and capital expenditures of the jointly owned units and stations.
