Engie’s two storage projects total nearly 1.7 GW; LS Power’s gas-fired generation uprate adds 455 MW.

Engie’s contribution consists of two storage projects totaling nearly 1.7 GW. That figure is their combined power capacity; the excerpt does not provide an individual project split, storage duration, or energy capacity in gigawatt-hours.

LS Power’s contribution is a 455-megawatt (MW) gas-fired uprate. The source identifies it as an increase in generation capacity, rather than describing a separate new 455 MW power plant.

These are the project components underlying the preceding 2.1 GW PJM headline, not an additional set of approvals. Utility Dive reports PJM’s expectation that the projects will be online by mid-2029, but supplies no project-level capital costs, financing terms, equipment specifications, or construction milestones.
