Environmental benchmarking
Environmental benchmarking is a tool for assessing and managing the environmental performance of Samruk-Energy JSC by comparing its own indicators with the results of leading companies in the sector. This approach facilitates the adoption of best international practices in environmental management and sustainable development. The current analysis uses publicly available data for 2022–2024:
The following indicators were defined for benchmarking:
- freshwater use for technological and domestic drinking purposes;
- direct (Scope 1) and indirect (Scope 2) greenhouse gas (GHG) emissions.
To identify environmental trends, the largest energy companies in Kazakhstan and globally were analyzed, namely:
- ERG;
- CAEPCO JSC;
- KKS LLP;
- Enel Group;
- Inter RAO PJSC;
- RusHydro PJSC.

Greenhouse gas emissions
Samruk-Energy JSC’s specific GHG emissions decreased from 0.93 tCO₂-eq./MWh in 2023 to 0.81 tCO₂-eq./MWh in 2024 (-13%). Regarding this indicator, the Company:
- −remains below ERG (1.53–1.57 tCO₂-eq./MWh), CAEPCO JSC (1.37–1.41) and KKS LLP (1.29–1.31);
- −demonstrates a comparable level with Inter RAO PJSC (0.59–0.60), considering differences in generation structure;
- −is higher than companies with a high share of renewable energy and hydroelectric power — Enel Group (0.15–0.27) and RusHydro PJSC (0.23–0.27).
Water Use
The average specific water consumption of Samruk-Energo JSC for 2022–2024 was 5.94 m³/MWh, which is:
- −17.3 times lower than ERG (~103 m³/MWh);
- −26% higher than RusHydro PJSC (4.96 m³/MWh);
- −21 times higher than Enel Group (0.28 m³/MWh), due to the high share of renewable energy in its generation mix.
