PROJECT PROFILE · CERTIFICATE-BASED CLIMATE PROTECTION
The plants at Cumayasa have a combined nominal capacity of 80 MW and are connected to the Dominican Republic's electricity grid via a 138 kV connection. This page separates the technical project activity, the methodologically calculated emission reduction, and the subsequent allocation of certificates.

WHY THE COMPARISON MATTERS
Electricity is measured. The difference to the grid without the project is calculated.
A photovoltaic system does not measure avoided tonnes of CO₂. It measures generated and fed-in electricity.
For the carbon footprint, this net feed-in is linked to an emission factor of the connected electricity system determined in accordance with ACM0002. Only the documented comparison with the baseline scenario yields an emission reduction for a clearly defined monitoring period.

Why the estimate and issuance are not the same: 138,385 t CO₂e is the expected annual value stated in the registry. The 69,330 VERs issued are based on the shorter, independently verified first monitoring period. For a concrete allocation, it is the serial numbers actually issued that count – not the annual estimate.
02 · WHAT THE PROJECT PROVIDES FOR
Two plants, one grid connection, one shared project balance sheet
Cumayasa 1 and 2 are described separately from a technical perspective, but are accounted for together in the Gold Standard registry. The decisive factor is the amount of energy quantifiably fed into the electricity grid.
01
Generate solar power
Both photovoltaic systems convert solar energy into electricity. The installed capacity describes the system capacity – not automatically the generation of an individual period.
02
Feed-in together
The electricity enters the national interconnected system of the Dominican Republic via the 138 kV connection and the Cumayasa substation.
03
Check operating data
Meter and SCADA data document the feed-in. Monitoring reports assign them to a period; an independent auditing body evaluates the data and calculation.
03 · HOW A UNIT IS CREATED
Grid feed-in is converted into a calculated emission reduction.
ACM0002 defines how grid-connected renewable electricity generation is accounted for against a baseline of the connected electricity system.
01
Set baseline
The reference scenario describes how the electricity in the national grid would have been provided without the two solar parks.
02
Measure net feed-in
The actual amount of electricity delivered to the grid during the monitoring period is recorded via measuring and SCADA systems.
03
Apply emission factor
The net feed-in is linked to the methodologically determined emission factor of the connected electricity system. Relevant project and leakage emissions are taken into account.
04
Verify and issue
Following independent audit, VERs with vintage and serial numbers can be issued in the registry. A subsequent retirement documents their specific use.
04 · DOCUMENTED ADDITIONAL CONTRIBUTIONS
The register entry mentions four SDG references
In the Gold Standard registry, SDGs 7, 8, 10 and 13 are designated as certified impact claims. The specific significance depends on the respective documented indicators and monitoring periods.
SDG 7 · ENERGY
Renewable generation capacity
The two plants provide additional photovoltaic capacity and feed electricity into the national grid.
SDG 13 · CLIMATE ACTION
Calculated emission reduction
The climate contribution is derived from the verified difference to the electricity system baseline. It applies to the respective monitoring and crediting framework.
SDG 8 · WORK
Project-based employment
Construction, operation and maintenance can stimulate employment and economic activity. The decisive factors are the specific indicators set out in the project documentation – not a flat-rate impact on jobs.
SDG 10 · REDUCED INEQUALITIES
Reported, verifiable reference
The register entry shows SDG 10. The associated target group, indicator and period must be classified based on the certification documents.
ON SDG COMMUNICATION
An identified SDG reference is not a general sustainability seal. It merely shows which additional areas of impact the project documents within the standard framework; it does not make the project or the supporting companies sustainable as a whole.
05 · FOR SUPPORTING COMPANIES
Issued VERs are not yet an allocation to a company.
A reliable allocation includes at least:
01
Project name and Gold Standard ID GS12212
02
specific quantity in t CO₂e
03
Vintage or monitoring period
04
Decommissioning date and register reference
05
full serial number range
06
Beneficiary and documented purpose of use
06 · CLASSIFICATION AND COMMUNICATION
What the support means – and what it doesn't
A voluntary climate contribution is presented separately from reductions within one's own value chain.
IT DOCUMENTS
IT DOES NOT AUTOMATICALLY MEAN
two photovoltaic plants with a combined 80 MW AC and shared grid feed-in
a continuous output of 80 MW or the direct supply of specific households
an emission reduction calculated and verified in accordance with ACM0002
a direct measurement of avoided CO₂ emissions at the solar panels
a Gold Standard-certified project with issued VERs
automatically an Article 6 authorisation, a CCP label or an external rating
Electricity generation without fuel combustion in plant operation
a complete life cycle assessment including raw materials, land use and end of life
the links to SDGs 7, 8, 10 and 13 shown in the registry
a comprehensive sustainability status for project, electricity or supporter
the retirement of specific CERs for a beneficiary
a reduction of own emissions, climate neutrality, or a green product label
