A landmark collaboration between B.Grimm and Siam Piwat Group is set to redefine sustainable development in Thailand through a multi-dimensional strategic partnership spanning renewable energy, digital innovation, biodiversity, holistic wellness, and cultural promotion.
The partnership was formalised through a memorandum of understanding (MOU) between B.Grimm – Thailand’s oldest established company with a 147-year legacy in nation building – and Siam Piwat Group, the visionary retail and real estate developer behind world-renowned destinations such as Siam Paragon, Siam Center, Siam Discovery, and ICONSIAM.
Central to this collaboration is the installation of a solar rooftop at Siam Paragon, alongside initiatives in energy efficiency, biodiversity conservation, knowledge exchange, and arts and culture. Together, both organisations aim to pioneer a model for sustainable business that harmonises innovation, environmental responsibility, and community well-being.
Clean Energy for a Sustainable Future
Under the agreement, Siam Paragon has signed a Power Purchase Agreement (PPA) with B.Grimm Power Smart Solution Co., Ltd., a subsidiary of B.Grimm Power Public Company Limited, to develop the solar rooftop project on the shopping centre’s building.
Covering more than 4,600 square metres with an installed capacity of 793 kilowatt-peak (kWp), the system is expected to reduce greenhouse gas emissions by approximately 532 tons annually. The electricity generated will power Paragon Hall, a world-class convention and exhibition centre, as well as a new zone within Siam Paragon scheduled to open in late 2025 – set to become a sustainability showcase and landmark in the heart of Bangkok.
Building on the success of the solar rooftop at ICONSIAM, the project will further increase the share of clean energy used across Siam Piwat’s portfolio, in line with its target of achieving 100% renewable energy across all shopping centres by 2030.
Shared Vision for Sustainability
Dr Harald Link, Chairman of B.Grimm, noted that the partnership reflects both companies’ long-standing commitment to driving Thailand’s progress in healthcare, infrastructure, and energy innovation.
‘With its heritage of doing business with compassion in harmony with nature, B.Grimm is dedicated to supporting sustainable development and future innovations that meet the needs of society in the digital age,’ said Dr Link. ‘We are delighted to collaborate with Siam Piwat, whose world-class properties bring happiness and meaningful experiences to millions of visitors every year.’
Beyond renewable energy, the partnership extends into biodiversity conservation, knowledge exchange inspired by Bhutan’s Gross National Happiness (GNH) concept, holistic healthcare, and promotion of classical music education through the Royal Bangkok Symphony Orchestra (RBSO) – Southeast Asia’s premier orchestra supported by B.Grimm.
Leading Thailand’s Transition to Net Zero
Chadatip Chutrakul, Chief Executive Officer of Siam Piwat Group, said the collaboration represents a new benchmark for sustainable destinations in Thailand.
‘This partnership with B.Grimm marks another significant milestone for Siam Piwat as we continue to integrate innovation and clean energy management to enhance efficiency and sustainability,’ said Ms Chadatip. ‘We have set an ambitious goal to achieve net-zero Scope 1 and 2 greenhouse gas emissions by 2050. This alliance underscores a shared vision to establish a truly ESG-driven business ecosystem that aligns with international sustainability standards.’
Siam Piwat’s sustainability strategy is embedded across all its destinations – Siam Paragon, Siam Center, Siam Discovery, ICONSIAM, ICS, and Siam Premium Outlets Bangkok – which are not only global lifestyle hubs but also platforms for social connection and environmental responsibility. The company’s ‘Creating Shared Value’ approach ensures that its success translates into long-term benefits for communities, the environment, and the nation.
In uniting innovation with compassion, B.Grimm and Siam Piwat are charting a clean-energy future that strengthens Thailand’s position as a regional model for sustainable progress.
