Bad Creek

Hydro power plant in South Carolina, United States of America. Approximate location 35.0075, -82.9975.

HydroSouth CarolinaUnited States of America

Bad Creek is a 2,000 MW hydro power station in South Carolina, United States of America. It is operated by Duke Energy Carolinas LLC. Based on its capacity (estimated), it can supply roughly 2.0 million homes (estimated). It ranks #215 of 10,938 United States of America power plants by installed capacity. Commissioned in 1991, it is around 35 years old — long-established. As a non-combustion source, it has no direct CO₂ emissions from generation. In context, hydro supplies about 5.3% of United States of America's electricity; the national grid averages 384 gCO₂/kWh (43.0% low-carbon) (2025).

Capacity provenance

The public capacity above is the current source-record value. A 2026 tracker candidate lists 2,000 MW for Bad Creek hydroelectric plant, but it is not used as the public primary value until scope is verified (unit vs operating vs installed/project total).

Capacity claim grade: A3_MAJOR_REVIEW_SCOPE_STATUS - recommended action: manual_scope_status_check - confidence: low_until_scope_verified. This follows a claim-based data model: value + scope + source + confidence, rather than silently overwriting records.

Data provenance

The capacity and/or fuel fields on this page include a source-backed provenance label from GEM, an official registry, Wikidata, OSM, or a cross-source match.

In context: how this plant compares

At 2,000 MW, Bad Creek is well above the median hydro plant in United States of America (8 MW). Hydropower converts the energy of falling or flowing water into electricity; output depends on rainfall and reservoir level, and large dams also provide grid balancing and storage.

Capacity comparison computed from the WRI Global Power Plant Database; fuel-type context is general engineering background.

Local climate & thermal context

This hydro plant converts the energy of falling or flowing water through hydro turbines. It sits in a temperate oceanic climate (Köppen Cfb) — Northern Hemisphere, latitude 35.0°N — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 31% below the median power plant in this dataset — a proxy for how much extra energy heated equipment must replace through its surfaces in winter.

Climate heat-demand index: 38/100 — this site sits in the mid third of the power plants we cover by heating degree-days.

Climate normals: WorldClim 2.1 (1970–2000 monthly normals, 10 arc-min, CC BY 4.0); zone: Köppen-Geiger world climate classification (Kottek et al. 2006, 0.5° grid). Degree-days & heat-demand index computed by PowerAtlas — a modelled heat-demand proxy, not a measured site figure.

Site climate & environmental severity

For a plant’s outdoor hardware — heat-recovery steam generators (HRSG), expansion joints, valves, flanges and their insulation — the local climate sets how fast unprotected steel and coatings degrade. This site sits in a moderately corrosive environment (estimated ISO 9223 class C3 — Medium), with humidity / wetness the leading environmental stress.

Higher environmental severity is exactly where protective removable insulation pays back most: a sheltered micro-climate slows corrosion, UV and thermal-cycling damage and extends outdoor hardware service life. This is an indicative site-climate context — not a condition assessment of any specific plant or operator.

Indicative estimate via the ISO 9223:2012 informative method (atmospheric corrosivity from temperature, time-of-wetness and airborne salinity), using WorldClim climate normals, the Köppen-Geiger class and coast distance. Indicative, not a measured corrosion rate.
