Tavera 1

Hydro power plant in Santiago, Dominican Republic. Approximate location 19.3104, -70.7437.

HydroSantiagoDominican Republicconventional storage

Tavera 1 is a 96 MW hydro power plant in Santiago, Dominican Republic. It is operated by EGEHID. Based on its capacity (estimated), it can supply roughly 96k homes (estimated). It ranks #18 of 30 Dominican Republic power plants by installed capacity. Commissioned in 1973, it is around 53 years old — an older, legacy facility. As a non-combustion source, it has no direct CO₂ emissions from generation. In context, hydro supplies about 6.7% of Dominican Republic's electricity; the national grid averages 537 gCO₂/kWh (23.8% low-carbon) (2025).

Capacity provenance

The public capacity above is the current source-record value. A 2026 tracker candidate lists 80 MW for Tavera 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: C_REVIEW_MANUAL - recommended action: manual_review_only - confidence: unknown. This follows a claim-based data model: value + scope + source + confidence, rather than silently overwriting records.

Data provenance

The capacity and fuel fields on this page are source-record values from the upstream open dataset. They are useful for identification and ranking, but they have not been upgraded to a 2026 registry/GEM-location verified value.

In context: how this plant compares

Technically it is described as conventional storage. 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 tropical rainforest climate (Köppen Af) — Northern Hemisphere, latitude 19.3°N — which shapes how much energy it can produce and how its output varies through the year.

This site has effectively no heating season (tropical/equatorial climate), so winter heat loss is not the driver here. The thermal concern shifts to year-round process heat and humidity/heat-driven corrosion of hot equipment.

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 an aggressive, high-corrosion environment (estimated ISO 9223 class C5 — Very high), with marine salt corrosion 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.
