Pennsylvania PUC Declines To Require Bring-Your-Own-Generation Under Adopted Model Large Load Tariff

The Pennsylvania PUC issued a written order and model tariff for interconnection of, and service to, large load customers

The model tariff and PUC order do not address direct retail market issues, such as default service for large load customers

While the PUC had in a tentative large load order entertained a potential bring-your-own-generation (BYOG) policy, the final order does not include any BYOG requirement or other BYOG provisions

"At this time, we are not persuaded by stakeholders' comments that it is either timely or within the scope of this model tariff to require Large Load Customers to bring their own generation. Therefore, we will not add provisions to the model tariff at this time related to requiring Large Load Customers to bring their own generation or any other energy efficiency and energy storage resources," the PUC said in the newly issued written order

The model large load tariff is to apply to customers with load at or over 50 MW individually or 100 MW in the aggregate across "multiple closely located customers"

Behind the meter generation shall be excluded from the MW threshold calculation.

An EDC shall have the authority to apply the large load tariff to customers below 50 MW individually or 100 MW in the aggregate on a case-by-case basis.

The new large load tariff is applicable to new large load interconnections (new customers and new incremental load of existing customers) connecting to the electric distribution system. "To clarify, an existing customer requesting to increase their load in which the site’s total load is at or over the MW thresholds in this tariff will be subject to this tariff’s provisions as a Large Load Customer," the model tariff states

Contract service for interruptible power will be available to large load customer customers based on the utility's existing interruptible service tariff provisions.

An EDC may offer eligible Large Load Customers an opportunity to receive service under options that provide mandatory capacity interruptions and discretionary energy interruptions pursuant to a contract agreed to by the EDC and the Large Load Customer. Minimum interruption requirements will be the minimum requirements under the PJM Interconnection, LLC (PJM) Emergency Load Response Program for capacity purposes, or successor thereto.

The model tariff includes provisions governing collateral, exit fees, minimum demand charges, interconnection, CIAC, and universal service fund fees, among other provisions
