An electric service provider:

(1) Shall make either bidirectional metering or single directional metering available to customer generators depending on how the distributed generation facility is connected to the distribution system of the electric service provider;

(2) Shall enter into a written agreement with the customer generator to charge the customer generator the rate established by the commission, or the appropriate governing body, in the case of any other electric service provider or electric supplier, for metering services;

(3) In setting the fees for metering service, the commission, or the appropriate governing body, in the case of any other electric service provider or electric supplier, will include the direct costs associated with interconnecting or administering metering services or distributed generation facilities and will not allocate these costs among the utility's entire customer base; and

(4) In establishing such a fee for metering services, the electric service provider shall not charge the customer generator any standby, capacity, interconnection, or other fee or charge, other than a monthly service charge, unless agreed to by the customer generator or approved by the commission, in the case of an electric utility, or the appropriate governing body, in the case of any other electric service provider or electric supplier.
