A. Title of the methodology
Installation of Run-of-river Small Hydropower Generation Plant, Version 01.0

B. Terms and definitions
Terms
Small hydropower plant

Definitions
A small hydropower plant is a hydropower plant with an
installed capacity of up to 10 MW1.

Run-of-river hydropower plant

A run-of-river hydropower plant is a type of hydroelectric
generation which does not have a dam2.

C. Summary of the methodology
Items

Summary

GHG emission reduction

Displacement of electricity using fossil fuel as a power source

measuresby installation and operation of a small hydropower plant.

Calculation of reference

The reference emissions are calculated on the basis of the netemissions

power output of the small hydropower plant which means thegross energy generation by the project small hydropower plant
minus the auxiliary/station electricity consumption, multipliedby the conservative emission factor.

Calculation of project

The project emissions are the emissions from the smallemissionshydropower plant, which are assumed to be zero.

Monitoring parameters

The quantity of electricity generated by the project smallhydropower plant.

1

If the installed capacity of the project hydropower plant is equal to or less than 30 kW and notconnected to national electricity grid on the day of validation, the approved methodology
KE_AM001 “Electrification of communities using Micro hydropower generation” may beapplied.
2
A dam is defined as a structure built across a river with a height greater than 15m or morefrom its foundation.

F. Establishment and calculation of reference emissions
F.1. Establishment of reference emissions
In order to identify the reference emission factor simplistically and secure net emission
reductions, this methodology applies the lowest emission factor of diesel power generation. The
most efficient diesel generator in the world has a generation efficiency close to 49%. A power
generation efficiency of 49% translates into an emission factor of 0.533 tCO2/MWh. This value
is lower than the lowest standardized grid emission factor in 2014, which is 0.5793 tCO2/MWhas the build margin calculated at that time addressed in the report published by the National
Environment Management Authority of Kenya (NEMA 2014). This will ensure net emission
reductions.
F.2. Calculation of reference emissions

RE p = EG p ´ EFRE
REp

: Reference emissions during period p [tCO2/p]

EGp: Quantity of electricity generated by project small hydropower plant during period p[MWh/p]

EFRE: Reference CO2 emission factor [tCO2/MWh]2

: Project emissions during period p [tCO2/p]

H. Calculation of emissions reductions
ERp = REp − PEp= REp
ERp: Emission reductions during period p [tCO2/p]

REp: Reference emissions during period p [tCO2/p]

PEp: Project emissions during period p [tCO2/p]
