WAC 194-37-130   Documentation of incremental hydropower.  (1) Utilities may count toward their annual renewable resource targets incremental power acquired from qualified incremental hydropower efficiency improvements made at the following facilities since 1999:

     (a) Hydropower facilities in the Pacific Northwest owned by a qualifying utility where the new generation does not result in new water diversions or impoundments.

     (b) Hydroelectric generation facilities in irrigation pipes and canals located in the Pacific Northwest, where the additional generation does not result in new water diversions or impoundments.

     (2) The utility shall calculate renewable resource power from incremental hydropower as the increase in annual megawatt-hours of generation attributable to the qualified incremental hydropower efficiency improvements under average water generation.

     (3) The increase in annual megawatt-hours of generation attributable to the qualified incremental hydropower efficiency improvements shall be documented by engineering studies or with before and after generation data. The documentation shall clearly explain:

     (a) Where the facility is located;

     (b) When the improvements were made;

     (c) How the amount of generation in "average water generation" was calculated;

     (d) What other factors may have caused an increase in electricity production and how the amount "attributable to the qualified improvements" was extracted from the total increase;

     (e) How and why the "qualified improvements" increased hydropower production; and

     (f) How the utility came to acquire the incremental output associated with the qualified improvements.
