Section 407-321-3 - TELEMETERINGA. Large Non-Residential Customers. For the purposes of this Chapter, transmission and distribution utilities shall use telemetering to measure hourly loads of all non-residential customers that are not within the small non-residential or medium non-residential profiling classes as they are defined in subsection 4.A.2. For transmission and distribution utilities that have a core customer class with a breakpoint of 500 kW, all customers with maximum demands of 500 kW or greater shall be considered Large Non-Residential Customers. For transmission and distribution utilities that have a core customer class with a breakpoint of 400 kW, all customers with maximum demands of 400 kW or greater shall be considered Large Non-Residential Customers. The transmission and distribution utilities shall recover the reasonable costs of equipment and data processing required by this provision. These costs will be recovered from the classes containing customers affected by this provision.B. All Other Customers. Competitive electricity providers may request that a transmission and distribution utility use telemetering to measure the hourly loads of any customer that receives generation service from that competitive electricity provider and that is not telemetered pursuant to subsection 3.A. The transmission and distribution utility shall charge the requesting competitive electricity provider the resulting incremental cost of equipment and data processing. The transmission and distribution utility shall accommodate requests for telemetering as quickly as practicable. The transmission and distribution utility shall telemeter hourly loads of all customers as long as the telemetering equipment remains installed.C. Phase-In of Telemetering. Upon a finding that transmission and distribution utilities cannot accommodate requests for telemetering in a reasonably timely manner, the Commission shall implement a phase-in approach that shall limit telemetering requests to customers using a prioritizing process to be determined by the Commission.65- 407 C.M.R. ch. 321, § 3
