1411846048 Market Test for Long-Term Firm, Dispatchable Capacity and Energy Resources - Addendum 5

JEA seeks Responses (the “Solicitation) to provide firm, dispatchable capacity and associated energy to help meet projected customer peak demands (plus reserve margin requirements) and energy requirements beginning in 2030. The Solicitation is supported by JEA’s long-term resource planning process, which indicates that JEA’s system will benefit from efficient, flexible, intermediate generation through the addition of an advanced-class combined-cycle facility. This addition would allow for the efficient utilization of natural gas while providing the JEA system with operational flexibility and dispatchability to reliably integrate increasing amounts of intermittent solar energy.

In the 2023 Integrated Resource Plan1, JEA identified the need for a flexible combined-cycle generation resource. JEA’s range for dispatchable net delivered capacity via this RFP is 525MW to 700MW. Though higher capacity options can be proposed, the proposal must include the cost of system upgrades and services needed to meet reliability and backup regulatory requirements relative to the loss of a single unit for the capacity exceeding 700MW. For the purpose of this requirement, a unit is defined as either 1) the rating of a single generator supplying the proposed capacity, or 2) the aggregated rating of all generators for interrelated CT(s) and ST(s) that make up a CCCT unit supplying the proposed capacity.

Responses are required to offer resources that provide firm capacity to contribute to meeting JEA’s peak demand as well as meeting JEA’s requirement for dispatch flexibility. Flexible capacity allows JEA to meet its energy requirements, including the ability to operate the resource as needed to support the integration of intermittent solar energy. Proposed resources are required to be available beginning on or before December 31, 2030.

JEA will evaluate all resource alternatives submitted, that comply with the requirements of this Solicitation, relative to a self-build resource. Unless a preferred resource alternative is identified through this Solicitation, JEA anticipates pursuing the development of the self-build option. Appendix A - Self-Build Option Information provides additional information regarding JEA’s self-build option.

It is anticipated that the generation technology having the highest likelihood of success as an alternative to the self-build option will be an advanced-class combined cycle technology resource, with operating parameters that include the ability to operate in baseload and load-following roles across the full unit load range. As part of any Response, regardless of technology, JEA must have sole rights to unit commitment and de-commitment, that includes dynamic scheduling (e.g., automatic generation control (“AGC”)). All Responses must be for a commercially-proven technology, meaning a technology that has a documented track record of being used in one or more commercial power projects (excluding proof-of-concept or prototype-piloting projects), has demonstrated successful operations, and is still in service.

While JEA’s resource planning process has identified a dual-fuel, advanced-class combined cycle as the preferred technology, other dispatchable technologies are not prohibited from being proposed in response to this Solicitation.
