Breakers and/or switches capable of isolating the qualifying facility from the electric utility shall at all times be immediately accessible to the electric utility.

System emergencies causing discontinuance of parallel operation are subject to verification by the commission. The facilities installed by the qualifying facility shall comply with 170 IAC 4-1-26(a) and the electric utility's rules and regulations for electric service in effect from time to time. The qualifying facility shall comply with the applicable requirements of 170 IAC 4-4.3.

  (b) To properly record the number of kilowatt hours being purchased or sold by the electric utility or qualifying facility, the following configurations shall be the basis for metering:

(1) When purchases by the electric utility from the qualifying facility are intended to be less than one thousand (1,000) kilowatt hours per month and the qualifying facility agrees, a single, bidirectional meter may be placed between the electric utility's system and the qualifying facility.

(2) When the qualifying facility will not be simultaneously selling to and purchasing from the electric utility, two (2) monodirectional meters shall be placed in a series arrangement between the electric utility's electric system and the qualifying facility, as shown as follows:
