VCS v5.0· grid connected
This route is for plants that send most of their power to the grid.
The three layers
Three layers. Most people think they are the same thing.
Three layers, one path. Most of the confusion in this market is people using those three words interchangeably.
- Standard
- VCS v5.0— the rulebook Verra publishes
- Methodology
- VMR0017— the recipe inside that rulebook for grid-export solar
- Tool
- Additionality tool— the calculation that decides whether you pass
Get those three words straight and this route stops being confusing. Most people never separate them.
Who it fits
- Solar that exports more than half its output to the grid.
- Any size — this route has no upper limit, and larger plants are simpler here, not harder.
- Plants that can register under the current rules before 1 January 2027.
- Owners who still hold the environmental attributes, unassigned.
What it commits you to
- Crediting period
- 5 years, renewable twice — no early exit
- Time to first payment
- 9 to 18 months from signature
- Deadline
- Register under current rules before 1 Jan 2027
- If the project was committed before 1 January 2027, three requirements defer to 2030: a stakeholder engagement plan, a benefit-sharing mechanism and a safeguards assessment.
- Once registered, a verification request is due within five years of your last approved one, or the project is marked late to verify on the registry.
What usually blocks it
Named honestly. Whether any of these apply to your plant is the part the full assessment answers.
The additionality test
You have to show the project needed the carbon revenue to stack up. A plant that was obviously going to be built anyway can fail here.
Export metering and grid factor
The value rests on how much grid electricity you displace, which needs clean export data and the right emission factor.
Attributes already assigned
PPAs and wheeling agreements routinely hand the environmental attributes to the off-taker without the owner noticing.
