To measure and make public the environmental consequences of power generation, transmission, and distribution.
Evaluate the environmental impact of electricity consumption, using the PEER EE index and the following formulae:
Overall performance metrics are the sum of the SEI, CO2, NOx, SO2, water intensity, and waste intensity for each generation source:
TDLi = Transmission and distribution losses (%) for generation source i (equals 0 for local generation)
WasteIi = 0 for nuclear and biomass, for rest of the fuel types please refer to the reference guide (or) EE Index calculator.
Table 1. Methane leakage multipliers
|All Other Fuel Types||1.000|
Sum the EE index scores corresponding to the values shown in Table 2. The first five metrics in Table 2 are maximums: the project’s value must not exceed the listed figure. The “waste recycled” metric, however, is a threshold: the project’s value must equal or exceed the listed figure.
Table 2. PEER EE index values
|SEI||CO2||NOx||SO2||Water Use||Waste Recycled||EE Index Score|
Additionally, establish a public disclosure policy to publish the results of environmental impact evaluations in the project’s annual performance and/or sustainability reports.
Projects that own or operate local or backup generation sources must meet following requirements:
- Have in place a process to record fuel consumption, water consumption, and energy output data for all local and backup generation units.
- Have in place a policy to verify the emissions performance of local and backup generation units through third-party testing at least once every three years.
- Demonstrate compliance with regional environmental regulations applicable to the local and backup generation units, including emissions, waste handling and disposal, water consumption, and land use.
