Biomass power plant in Biobio, Chile. Approximate location -37.2895, -72.7114.
BiomassBiobioChile
CMPC_Laja is a 25 MW biomass power plant in Biobio, Chile. It is operated by CMPC CELULOSA S.A.. Based on its capacity (estimated), it can supply roughly 34k homes (estimated). It ranks #170 of 336 Chile power plants by installed capacity. In context, biomass supplies about 5.7% of Chile's electricity; the national grid averages 289 gCO₂/kWh (66.4% low-carbon) (2025).

Known, modelled and calculated values are kept separate. Missing fields are shown as unavailable.
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.

At 25 MW, CMPC_Laja is well above the median biomass plant in Chile (14 MW). Biomass plants burn organic material such as wood, residues or waste-derived fuel to raise steam; they are dispatchable and counted as low-carbon where the feedstock is sustainably sourced.

This biomass plant burns organic material (wood, residues) to raise steam for a turbine. It sits in a warm-summer Mediterranean climate (Köppen Csb) — Southern Hemisphere, latitude 37.3°S — which shapes how much energy it can produce and how its output varies through the year.
Monthly mean temperature
Heating degree-days here run 29% 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: 39/100 — 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.
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.
The #5 largest biomass power plant of 22 in Chile by capacity.
