Kentucky Interconnection Standards
|Date Last Updated||8/11/2014|
|Policy Type||Interconnection Standard|
|Policy Administrator/Contact Office||Kentucky Public Service Commission (PSC)|
|Policy Initiation Date||1/8/2009|
|Policy Summary||Kentucky PSC has established interconnection standards that apply to CHP. The standards apply to all retail electric suppliers in the state, excluding TVA utilities. Kentucky's interconnection standards apply only to certain renewables (PV, wind, biomass, biogas and small hydro) up to 30 kW.|
There is a two-tiered interconnection process for eligible systems:
Utilities may choose to require an external disconnect switch. In addition, customers must maintain general liability insurance coverage (e.g., a standard homeowner's or commercial policy) for their systems. The guidelines also cover procedures for dispute resolution.The PSC has also ruled that the customer retains all renewable-energy credits (RECs) associated with the generation of renewable electricity.
- Level 1: applies to inverter-based systems up to 30 kW that are certified to the UL 1741 and comply with IEEE 1547. Systems cannot require the utility to make modifications to its system in order to be interconnected. Utilities must notify the customer within 20 business days whether the interconnection application has been approved or denied. No application fees or other related fees apply.
- Level 2: applies to systems that are not inverter-based or that use equipment not certified as meeting UL 1741 or for systems that fail to meet the other technical requirements outlined for Level 1 Applications. The utility has 30 business days to process a Level 2 application. Utilities may require customers to submit an application fee of up to $100 for processing and inspection purposes. If the utility determines that an impact study is needed, the customer is responsible for costs up to $1,000 for the initial impact study.
Note: A utility may negotiate a contract interconnection with a merchant or co-generation electric generating facility with a capacity of up to 10 megawatts. This customer would most likely incur some significant initial costs for equipment, possible grid/line upgrades, safety devices, and insurance. By law, larger systems may establish interconnection, but only after receiving approval from the PSC/Siting Board.
|CHP Eligibility Requirements||CHP systems using renewable fuels are eligible for standardized interconnection.|
|Eligible Project Size (MW)||Standardized interconnection applies to systems up to 30 kW.|
