- Description: Riverside Generating LLC is an operating natural-gas-fired simple-cycle plant in Lawrence County, Kentucky, with five 230 MW-class combustion-turbine units totaling 1,150 MW of nameplate capacity. The facility is physically one Riverside site, while PJM identifies Units 1–3 as Zelda and Units 4–5 as Foothills; the first three units entered service in 2001 and the latter two in 2002. Dynegy developed the Riverside and Foothills phases, LS Power acquired the Riverside asset from Dynegy in December 2009, and NRG completed its acquisition of the LS Power generation portfolio in January 2026. KBR provided EPC services, Siemens supplied the turbines, and IHI Power Services provided operation and maintenance services beginning in 2018. — LS Power Completes Purchase of Generating Assets from Dynegy - LS Power · confidence: medium
