Oaxaca III · Mexico
VCS1042 describes a grid-connected wind farm near Juchitán de Zaragoza with an installed capacity of 102 MW. This page separates technical capacity, measured grid feed-in, calculated emission reductions, registry status and the subsequent allocation of VCUs.

WHY FEED-IN MATTERS
For the project balance sheet, the documented grid feed-in is linked with a methodologically determined emission factor of the Mexican electricity system. Only this comparison results in a calculated emission reduction for a clearly defined monitoring period.
The technology generates electricity. The method determines which emissions are offset by this electricity in the reference case.

What the monitoring value shows: 345,162 t CO₂e relate to the period 01/12/2019–30/11/2021. The value is neither an annual emission reduction nor a current update beyond the end of this period.
What the end of the crediting period means: The registry entry specifies 14/01/2022 as the end date of Term 1. The technical operation of a wind farm and the issuance of new VCUs are separate issues. The "Registered" status alone does not imply continuous crediting after this date.
Discrepancy between sources: The submitted monitoring documents sometimes state different date limits in the VCS/CDM context. For the current profile, the crediting period shown in the Verra registry is used; the historical documents remain identifiable as source context.
02 · WHAT THE PROJECT PROVIDES FOR
Generate wind power, feed it into the grid and record it traceably
For the carbon footprint, it is not only the installed capacity that counts. What is decisive is the amount of electricity generated within a specified period and fed into the grid at the defined metering point.
01
Using wind on the isthmus
The project context describes 68 wind turbines with a combined capacity of 102 MW in a windy region of Oaxaca. The installed capacity alone does not yet constitute an emission reduction.
02
Feed electricity into the grid
The electricity generated is fed into the Mexican power system and sold to CFE. It does not follow that specific households, products or companies are directly supplied with this electricity.
03
Document creation
Measurement data, calculation documents and independent audits form the basis for the quantification and possible issuance of VCUs for defined periods.
03 · HOW A UNIT IS CREATED
ACM0002 forms the methodological framework mentioned in the documents for grid-connected electricity generation from renewable sources.
01
Set baseline
The reference scenario describes how the corresponding amount of electricity would have been provided without the project in the Mexican electricity system.
02
Measure electricity quantity
The electricity actually generated and fed in at the defined metering points is documented for the monitoring period.
03
Apply emission factor
The eligible amount of electricity is linked to the methodologically determined emission factor of the electricity system. Relevant project and leakage emissions are taken into account.
04
Verify and issue
Following independent auditing, VCUs with vintage and serial numbers can be issued in the registry. A subsequent retirement documents their specific use.
04 · OTHER PROJECT REFERENCES
The VCS project framework quantifies greenhouse gas emissions. Energy, infrastructure, employment or environmental references require their own data and evidence; they do not follow automatically from an issued VCU.
ENERGY SYSTEM
102 MW of wind power in the interconnected grid
The wind farm expands the grid-connected generation capacity from wind energy. Which conventional generation is offset in the reference case is methodologically considered via the baseline.
MONITORING
Generation at the defined metering point
The documents describe the preparation of electricity data on an hourly, monthly, and annual basis. Data checking and evidence reconciliation are part of the verification.
INFRASTRUCTURE
Technical operation over years
A wind farm is a long-term energy infrastructure. Nevertheless, statements regarding employment, regional value creation, or security of supply require their own indicators.
ENVIRONMENT
No combustion during plant operation
Wind energy does not require fuel during operation. A complete environmental assessment would nevertheless have to include manufacturing, grid connection, land use, and end-of-life.
FOR COMMUNICATION
A link to renewable energy or the Sustainable Development Goals is not a comprehensive sustainability credential. What matters is which specific statement is supported by which indicator, which source, and over which time period.

Beneficiary and documented purpose of use
The profile explains the project. A company's actual climate contribution is only proven by the retirement and allocation certificate.
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.
CAN BE DOCUMENTED
IS NOT AUTOMATICALLY ASSIGNED
a VCS project with the current registration status 'Registered'
continuous crediting beyond the end of the specified period
an emission reduction calculated in accordance with ACM0002 and verified for completed periods
a direct measurement of avoided CO₂ emissions at the wind turbine
102 MW of installed capacity from 68 turbines of 1.5 MW each
a certain amount of electricity, utilisation or emission reduction without a specific time period
a declaration on the handling of CDM and other environmental credits for the same monitoring period
a general guarantee that any risk of double counting is excluded
Wind power with zero fuel combustion during plant operation
a complete life cycle assessment including manufacturing, infrastructure and end of life
the retirement of specific VCUs for a beneficiary
a reduction of own emissions, climate neutrality, or a green product label
It is not the wind turbine that occupies the climate protection unit. Rather, it is the audited period, the issued VCU and its unique allocation.
