13.2.1 Low-carbon energy tracking

Measuring the amount of low-carbon energy used at the University

Srinakharinwirot University (SWU) measures the amount of low-carbon energy used at the University and tracks the total energy used across the university, so that the share of energy from low-carbon sources can be followed over time. Under the SWU Zero Carbon policy, announced on 13 December 2024, the University promotes alternative energy such as solar cells and floating solar systems (item 4) and tracks its energy use towards carbon neutrality for Scope 1 emissions by 2050 and net zero greenhouse gas emissions by 2065.

Tracking total energy use and solar generation

SWU records the monthly electricity consumption of its two campuses and the renewable electricity generated by the university’s own solar PV systems, a low-carbon source, through the SWU SDG Sustainability Web App dashboard. For each solar system, the dashboard records, by month and by building, the electricity generated, the electricity exported to the grid, the building’s actual electricity use and the share of that use met by solar power, in both kWh and GJ.

In 2025 (B.E. 2568), the total energy used was 55,710,830 kWh of electricity (200,559 gigajoules, GJ). Solar PV systems on the Administration Building and the HRH Princess Maha Chakri Sirindhorn Medical Center at Ongkharak Campus generated 128,773.89 kWh (463.59 GJ) of low-carbon energy, equal to 0.23% of the total energy used, of which only 162.83 kWh was exported to the grid. The Administration Building system supplied about 14% of the building’s electricity use over the year.

Monitoring smaller solar installations

Smaller solar installations are monitored through their inverter monitoring applications. The solar system at the University’s bioshop generated 721.27 kWh of electricity in 2025, and its records show 2.52 MWh generated in total from 2023 to October 2026, all of which was used on site.

Together, these records form SWU’s low-carbon energy tracking: each month the University measures its total energy used and the amount of low-carbon energy generated and used on campus. The tracking data are published on the University’s online dashboard, so the evidence is publicly available.
