"NEW SECTION.  Sec. 1   A new section is added to chapter 19.29A RCW to read as follows:
     (1) Except as provided in subsection (2) of this section, a state agency that is served by a public or private utility, must purchase all available anaerobic digestion power from the local utility when the producer of the power sends a written purchase request to the agency. Purchases by a state agency shall not exceed the agency's annual electricity consumption. A state agency shall pay for anaerobic digestion power at no less than the retail price that the local utility charges that customer.
     (2) State agencies are not required to purchase all available anaerobic digestion power from their local utility if their utility is exempt from offering a qualified alternative energy resource as defined in RCW 19.29A.090.
     (3) To the extent that a utility purchases power from an anaerobic digestion power producer in its service territory, the utility must pay the producer no less than the retail price the utility charges a state agency in this section, although administrative costs may be charged that do not exceed five percent.
     (4) For the purposes of this section, "anaerobic digestion power" means the electricity generated from an in-state facility that processes manure or other organic substrates into biogas using microorganisms in a decomposition process within a closed, oxygen-free container."
