AMS-I.D.

Full explainer

AMS-I.D. is a CDM small-scale methodology for grid-connected renewable electricity, accepting hydroelectric, wind, solar, biomass, and geothermal projects up to 15 MW (the small-scale CDM threshold). The methodology calculates emissions reductions by displacing fossil generation on the connected grid; the displacement factor is the country-specific or regional grid emission factor.

In Indonesia, AMS-I.D. has been used in particular for small-scale hydro and biomass plants connected to PLN's regional grids. It is often combined with AMS-III.H. (landfill gas / methane recovery) or with biomass-specific methodologies. With the CDM closing to new registrations post-2024, projects are migrating to Verra's VCS framework (VM-class methodologies) or to PACM under Article 6.4. Existing AMS-I.D. issuances continue to trade on the secondary CER market.
