  1. Scope, applicability, and entry into force

2.1. Scope

This methodology covers renewable energy generated by photovoltaic panel facilitys:

(a) Supplying electricity to a commercial grid; or

(b) Supplying electricity to the facility owners for use on-site

2.2. Applicability

This methodology is applicable to project activities that:

(a) Install photovoltaic panels;
(b) Add additional capacity to (an) existing facility(s);
(c) Involve retrofit of (an) existing facility(s);
(d) Involve rehabilitation of (an) existing facility(s); or
(e) Involve replacement of (an) existing facility(s).

In the case of project activities that involve the capacity addition of renewable energy
generation units at an existing renewable power generation facility, the added capacity
of the units added by the project should physically distinct from the existing units.

2.3. Entry into force

The date of entry into force 15 May 2022

  1. Definitions

For the purpose of this methodology, the following definitions apply:

(a) Backup Generator – a generator that is used in the event of an emergency, such
as power supply outage due to either main generator failure or grid failure or
tripping of generator units, to meet electricity demand of the equipment at power
plants/units site during emergency;

(b) Capacity Addition – a capacity addition is an investment to increase the
power generation capacity of existing installations through: (i) the installation of
new photovoltaic panels besides the existing panels; or (ii) the installation of new photovoltaic panels, additional to the existing facility. The new photovoltaic panels in the case of capacity addition continue to operate after the implementation of the project activity;

(c) Greenfield Facility – a new photovoltaic panel facility that is
constructed and operated at a site where no renewable energy facility was
operated prior to the implementation of the project activity;

(d) Installed Power Generation Capacity (or installed capacity or rated
capacity) – the installed power generation capacity of a photovoltaic panel facility is the capacity, expressed in Watts or one of its multiples, for which the panels have

been designed to operate at nominal conditions. The installed power generation
capacity of a photovoltaic panel facility is the sum of the installed power generation capacities of the panels;

(e) Rehabilitation (or refurbishment) – is an investment to restore an existing photovoltaic panel facility that was severely damaged or destroyed. The primary objective of rehabilitation or refurbishment is to restore the performance of the facility. Rehabilitation may also lead to increase in efficiency, performance or power
generation capacity of the facility with/without adding new photovoltaic panels;

(f) Replacement – is an investment in new photovoltaic panels that replaces one or
several existing photovoltaic panel facilities in the project. The new photovoltaic panels have the same or a higher power generation capacity than the facility that was
replaced;

(g) Retrofit – or modification is an investment to repair or modify existing facilitiess, with the purpose to increase the efficiency, performance or power generation capacity of the facility, without adding new photovoltaic panels. A retrofit restores the installed power generation capacity to or above its original level. Retrofits shall only include measures that involve capital investments and not regular maintenance or housekeeping measures.

Baseline Methodology

5.1. Project Boundary

The spatial extent of the project boundary includes all photovoltaic panel facilities connected physically to the commercial electricity grid and/or the on site end .

5.2. Baseline Scenario for Greenfield Facility

  1. The baseline scenario is that the electricity delivered to the grid by the project activity
    would have otherwise been generated by the operation of grid-connected power plants
    and by the addition of new generation sources into the grid.

5.3. Baseline Scenario for Retrofit, Rehabilitation or Replacement

  1. For project activities that involve retrofit, rehabilitation or replacement of an existing
    facility, the baseline scenario is the continuing operation of the existing facility.

The methodology uses historical electricity generation data to determine the electricity
generation of the existing facility in the baseline scenario, assuming that the historical
situation observed prior to the implementation of the project activity would continue. In
the absence of the project activity, the existing facility would continue to provide  electricity to the grid or on site end user at historical average levels until the time at which the photovoltaic panel facility would be likely to be retrofitted, rehabilitated or replaced in the absence of the project activity. From that point of time onwards, the baseline scenario is assumed to correspond to the project activity, and baseline electricity supply is assumed to equal the project’s net electricity supply and no emission reductions are assumed to occur.

5.4. Baseline Scenario for Capacity Addition

  1. If the project activity is a capacity addition to an existing grid-connected photovoltaic panel facility, the baseline scenario is the existing facility that would continue to
    supply electricity to the grid at historical levels, until the time at which the generation
    facility would likely be replaced or retrofitted and electricity delivered to the grid by the added capacity would have otherwise been generated by the operation.

5.5. Calculating CO2e Emissions Reductions

 

Our basic formula is:

(Megawatts generated * emission coefficient) ÷1000 = metric tons CO2e

Where:

Megawatts generated = Quantity of net electricity generation that is produced and fed into the grid, or to an on-site end user as a result of the installation of photovoltaic panels in Megawatt hours (MWh)

Emissions coefficient = a representative value relating the quantity of CO2e gases produced per kWh of grid-generated electricity. The emission coefficient varies greatly over time and space, depending upon the method of generation and the specific fuel consumed.

Emissions coefficients are drawn from official sources (where available) and made
publicly available.

Example:

For 1 MW of grid-generated electricity using the current 550 grams of CO2e per Kwh Israel coefficient

1 MW * 550 grams/kWh = 550,000,000 grams.

550,000,000 grams = 550 metric tons.

In other words, 1 MW of grid-generated electricity results in the release of 550 tons of CO2e gases per annum. Conversely, a photovoltaic panel facility generating 1 Mw of renewable energy would annually prevent the emission of 550 tons of CO2E gases.

5.6 Proration of Part-Year Production

The example above assumes a facility is in operation producing electricity for an entire year. In accordance with our commitment to accurate, conservative crediting of emissions reductions, we prorate the production of facilities that are in operation for less than a ull year. For example, a new photovoltaic facility that began producing on July 1 would be credited with half of the 275 tons of emissions reductions, half of the 550 tons as in the example, to account for the fact that it had been in operation for only six months.

5.7 Allowance for Age-Related Production Decrease

 

Photovoltaic panels have a lifetime of 25 years. However the electrical output from such panels decreases by approximately 2 percent per year. We account for this decrease when making calculations. For a single year calculation we reduce the estimated by 2 percent for each year the photovoltaic facility has been in operation. For multi-year calculations we reduce the estimated output by 2 percent for each consecutive calculation. In the event there is verifiable, documented evidence of the actual output of an installation, for example meter reading from the commercial grid operator, we of course will use that data in place of calculating estimated output.
