Electricity is a key factor in the operation of the water pumping and distribution system and also constitutes a major cost for the Company. Electricity consumption varies in accordance with the volume of water pumped through the water grid, which comprises 19 main pumping stations and 55 substations with water metering stations. Therefore, the Company places importance on maintaining the stability and continuity of the water pumping and distribution system (reliability) in order to support water demand from all user sectors. To achieve this, the Company has set a target to prevent damage to machinery and equipment that could cause interruptions to the water pumping and distribution system or result in water supply disruptions from the main water grid.

The Company has established criteria for planned water supply interruptions for maintenance to be limited to not more than eight hours per occurrence. For machinery or equipment classified as highly critical (Class A), no operational shutdown is permitted in order to maintain the long-term stability and reliability of the water infrastructure system.

In addition, the Company places importance on achieving maximum efficiency in energy use and has continuously implemented energy conservation projects in both the water pumping and distribution process and office buildings in order to reduce energy consumption while improving energy efficiency across the Group through the Energy Management Working Group. This not only helps manage the Company’s operating costs but also contributes to mitigating “global warming.” The Company’s energy conservation initiatives cover the Group’s energy consumption in the following areas:

1. 11 pumping stations registered as controlled factories including:
   Nong Pla Lai Pumping Stations (2–3), Bang Pakong Pumping Station / Bang Pakong Low-Pressure Pumping Station, Chachoengsao Pumping Station, Bang Phra Reservoir Pumping Station, Samnak Bok Booster Pumping Station, Prasae Pumping Station, Nong Kho Pumping Station, Thab Ma Pond High-Pressure Pumping Station / Thab Ma Pond Low-Pressure Pumping Station, Khlong Thab Ma Pumping Station, Rayong River Pumping Station, and Industrial Water Production Pumping Station. In addition, two pumping stations are currently under registration as controlled factories, namely Nong Pla Lai Booster Pumping Station and Map Ta Phut Booster Pumping Station.
2. 1 controlled building
   i.e., the Head Office Building. Each year, energy conservation targets are determined based on the results of the previous year’s energy conservation potential assessment in order to reduce energy consumption in the following year at the organizational, production or service, and equipment levels, taking into account the level of energy loss and opportunities for improvement.
3. 55 power substations.
4. 17 water supply and other operations of UU Public Company Limited (UU PCL), including industrial water production systems, wastewater treatment systems, and reclaimed water systems.
