Description: The interconnection rules adopted by the PRC in July 2008 for the interconnection of qualified facilities with a maximum capacity of 10 MW simplify, including the interconnection of cogeneration. Four levels of capacity are distinguished, with lower capacity systems requiring less rigorous interconnection processes. All systems must comply with existing local and national procurement standards – including NEC, IEEE and UL standards – and circuit breakers are required on all systems. The CPP may require a production facility to purchase insurance and interconnection customers are required to pay a reasonable application fee. Municipal authorities are excluded from these standards because they are not regulated by the CPP. For solar-scale power installations, integration requires more frequent transmission upgrades to the local distribution system. Often, the costs of these transmission upgrades, which can be in the tens of millions, are borne by the solar project developer and not by the transportation network manager. A major obstacle to a greater level of integration of solar energy at the supply scale is therefore the interconnection process in many parts of the country, an obstacle that industry organizations, such as the Interstate Renewable Energy Council and the Solar Energy Industries Association, actively want to mitigate. Description: On January 5, 2007, the Tennessee Regulatory Authority (TRA) issued in Dockets 06-00182 and 06-00183 Orders from the Tennessee authorities, it is indicated that Entergy and Kentucky Utilities have already implemented standards 11 (net measurement), 14 (time-based measurement) and 15 (interconnection), as described by PURPA in 2005, prior to August 8, 2005 , no further review of these standards by TRA was necessary (i.e., there was no need to change existing standards.
Description: Indiana`s link rules are three different connection levels, and the PCCE is explicitly eligible. There is no size limit for cogeneration facilities, but for facilities over 2 MW, higher fees are charged for the necessary pre-study. In general, it is easier to make a connection when a system complies with IEEE 1547 standards. Description: Louisiana requires regulated distribution companies to liaise with distributed production systems using renewable fuels.
