For information on how to interpret these reports, see below.
For each of the major utilities, information is divided into before-2004 and 2004-to-present. Information presented for Washington state operations only is not time segregated. Information is further grouped into 12 distinct sections:
Section 1: Balance Sheet – Assets and Liabilities
Section 2: Net Income Statement – All Operations
Section 3: Unappropriated Retained Earnings Statement
Section 4: Unappropriated Undistributed Subsidiary Earnings Statement
Section 5: Appropriated and Restricted Retained Earnings Statement
Section 6: Electric Plant in Service
Section 7: Net Operating Income Statement – Electric Only
Section 8: Sources of Energy – Megawatt hours
Section 9: Disposition of energy – Megawatt hours
Section 10: System Statistics
Section 11: Plant Statistics
Section 12: Electric Division Statistics
Annual data for sections 1 through 5 are provided for total company operations only. Data for sections 6 through 12 are provided both by total company and Washington state operations. Time series financial and operational data is presented in tabular form in this report both in aggregate and individually for each of the three electric utilities. Since Puget Sound Energy operates only within the state, the "Company Total" and "State Operations Only Total" are identical. Additionally, the reports include information on generation capacity for following categories: fossil fuel (including coal and natural gas), hydraulic, other non-fossil generation (includes bio-fuels, geo-thermal, solar, and wind), and nuclear.
As in any attempt to develop continuous and comparable time series data,
As in any attempt to develop continuous and comparable time series data, the primary difficulty of comparing or updating these reports is the assurance of comparability between elements. Though comparability is assured at broad group levels, the individual elements that are added are due to changes in accounting systems and pose a continuous problem for comparison over time. These problems are compounded by a lack of a comprehensive database that is capable of highlighting these differences or providing consistent information. Considerable efforts are undertaken to accommodate these changes and revisions and improvements are incorporated as and when they become appropriate.
