The Thai government is accelerating its Green Hospital initiative through the installation of solar rooftop systems at public hospitals nationwide, aiming to reduce energy costs, improve sustainability, and support the country’s long-term climate goals.

According to Deputy Government Spokesperson Lalida Periswiwatthana, the initiative reflects the government’s commitment to sustainable development while enhancing public healthcare services.  The Ministry of Public Health and the Provincial Electricity Authority (PEA) have signed an agreement to install and manage solar rooftop systems at 25 pilot hospitals under the Ministry of Public Health.

Minister of Public Health Pattana Promphat stated that the project supports Thailand’s goals of achieving carbon neutrality and net-zero greenhouse gas emissions by 2050. The ministry is implementing its Net Zero MOPH policy to transform healthcare facilities into environmentally responsible organizations through improved energy management and reduced carbon emissions. 

Public hospitals operate around the clock and face substantial energy costs. Last year, hospitals under the Ministry of Public Health recorded electricity expenses exceeding THB5.6 billion. The adoption of solar energy is expected to strengthen energy security while reducing long-term operational costs.

The pilot phase is projected to reduce greenhouse gas emissions by approximately 7,211 tonnes of carbon annually and generate electricity savings of more than THB55 million per year, averaging THB2.2 million per hospital. Savings from lower energy costs will be redirected toward improving medical services and patient care. Officials indicated that the programme will eventually be expanded to hospitals across the country, supporting Thailand’s transition toward clean energy, lower public-sector costs, and a more sustainable healthcare system.
