Elevating Social Investment Standards via SIF: Quantifying the True Social Value of the "Light for Life" Project

Sermsang Power Corporation Public Company Limited (SSP) is steadfast in its commitment to conducting business under a Sustainable Development (ESG) framework. We believe that effective social initiatives must extend beyond mere delivery; they must demonstrate proven value and substantiate the positive impacts generated.

In 2025, the Company collaborated with the Thaipat Institute to implementing the Corporate Social Impact Footprint (SIF) assessment tool for the ‘Light for Life – Clean Energy for a Sustainable Future’ project. This assessment benchmarks against the global GRI Standards and adheres to Social Return on Investment (SROI) principles to transform abstract outcomes into tangible, measurable value.

SIF Evaluation Results

Based on the assessment of the solar rooftop installation and learning promotion initiatives across three target areas in Sakon Nakhon Province—Na Kha Wittaya School, Wat Tha Samran, and the Khua Kai Subdistrict Administrative Organization (SAO)—the SIF tool has summarized the value-based results and operational efficiency as follows:

1. Financial and Social Value the SIF tool analyzed cost-effective investment by converting social outcomes into Monetary Value:
