Owner data does not fully agree across sources.
EIA typically reports the operating utility, while GEM resolves to the financial owner or parent corporation. Both can be correct.

The Neptune Energy Center Hybrid is a 450 MW hybrid power plant located in Pueblo County, Colorado. The plant, which began operating in 2023, is owned by NextEra Energy and operated by Neptune Energy Center, LLC. It utilizes both solar photovoltaic and battery storage technologies, with single-axis tracking for the solar panels. The battery energy storage system (BESS) has a capacity of 500 MWh and a duration of 4 hours, employing lithium-ion battery chemistry (LIB).
The plant's primary fuel source is electricity (MWH). In its latest year of operation, the Neptune Energy Center generated 679,256 MWh, achieving a capacity factor of 17.2%. The facility consists of two generators and operates within the Public Service Company of Colorado balancing authority, under the Western Electricity Coordinating Council (WECC) NERC region. According to available data, the Neptune Energy Center Hybrid is ranked as the second largest of four hybrid plants in Colorado, and 77th out of 514 nationally. Financial data is available for the plant from LBNL Solar.

This plant is in a bilateral market territory without organized wholesale pricing. Nodal pricing data is not available.
No wholesale contracts disclosed in FERC EQR for this plant.
FERC EQR captures bilateral wholesale energy + capacity contracts ≥$1M/yr filed quarterly by jurisdictional sellers — covers renewable PPAs, thermal energy sales agreements, capacity contracts, and tolling agreements alike. Many plants don't appear: regulated-utility output flows to ratepayers via cost-of-service rather than bilateral contracts; small projects fall below the filing threshold; tax-equity-financed renewables route offtake to investors not utilities; merchant plants sell into ISO clearing markets without bilateral contracts. News-extracted buyer facts (below) may surface contracts disclosed only through announcements.
