The system also includes ancillary equipment such as
inverters required to change the electrical current fromdirect current (DC) to alternating current (AC).

Storage battery system

The storage battery system which is consisted of power
converter(s) and connected group of battery cell charges anddischarges itself by converting electrical energy into
chemical energy.

Summary
reduction Displacement of grid electricity and/or captive electricity bymeasuresinstallation and operation of solar PV system(s) and storage
battery system(s).

Calculation

ofreference Reference emissions are calculated on the basis of the amount ofemissionsthe electricity displaced by the project multiplied by either: 1)
conservative emission factor of the grid, or 2) conservativeemission factor of the captive diesel power generator.

Calculationofproject Project emissions are the emissions from the solar PV system(s)emissionsand the storage battery system(s), which are assumed to be zero.

Monitoring parameters

The quantity of the electricity generated by the project solar PVsystem(s) and charge and discharge amounts of the storage
battery system(s) as necessary depending on the selected option1

D. Eligibility criteria
This methodology is applicable to projects that satisfy all of the following criteria.
Criterion 1

The solar PV system(s) and storage battery system(s) are newly installed.

Criterion 2

The PV modules are certified for design qualifications (IEC 61215, IEC 61646 orIEC 62108) and safety qualification (IEC 61730-1 and IEC 61730-2).

Criterion 3

The equipment to monitor output power of the solar PV system(s) and irradianceis installed at the project site.

Criterion 4

In the case of replacing the existing storage battery system (s), a plan is preparedin which mercury used in the existing storage battery system (s) is not released tothe environment. Execution of the prevention plan is checked at the time ofverification, in order to confirm that mercury used for the existing one replacedby the project is not released to the environment.

F.1. Establishment of reference emissionsThe default emission factor is set in a conservative manner for the Indonesian regional grids.
The emission factor is calculated based on the conservative operating margin that reflects on thelatest electricity mix including low cost/must run (LCMR) resources for each regional grid inIndonesia during the year 2013-2015 and refers to the conservative emission factor of eachfossil fuel power plant in order to secure net emission reductions. The conservative emission
factor of each plant are calculated as 0.795 t-CO2/MWh for coal-fired power plant and 0.320
t-CO2/MWh for gas-fired power plant based on the survey on heat efficiency of power plant in2

JCM_ID_AM017_ver01.0
Sectoral scope: 01Indonesia. The emission factor for diesel power plant is calculated as 0.533 t-CO2/MWh basedon a default heat efficiency of 49%, an efficiency level which is above the value of the world’s
leading diesel power generators.
In case the PV system(s) in a proposed project activity is directly connected or connected via aninternal grid, not connecting either an isolated grid or a captive power generator, to anational/regional grid (PV Case 1), the value of operating margin including LCMR resources,using the best heat efficiency among currently operational plants in Indonesia for the calculated
emission factors of fossil fuel power plants, is applied. The emission factors to be applied areshown in column “Emission factor for PV Case 1 (tCO2/MWh)” of Table 1 of the additional
information.
In the case the PV system(s) in a proposed project activity is connected to an internal gridconnecting to both a national/regional, and an isolated grid and/or a captive power generator(PV Case 2), the lower values between emission factors as shown in Section I. and theconservative emission factors of diesel-fired power plant of 0.533 t-CO2/MWh is applied. Theemission factors to be applied for PV Case 2 (t-CO2/MWh) are shown in Section I.
In the case that the PV system(s) in a proposed project activity is only connected to an internal
grid connecting to an isolated grid and/or a captive power generator (PV Case 3), the emission
factor of a diesel generator calculated by applying the efficient heat efficiency of 49%, anefficiency level which has not been achieved yet by the world’s leading diesel generator isapplied, which is set as 0.533 tCO2/MWh.
The result of calculation for emission factors to be applied for each case is shown in Section I.
