The mains electricity supply continues to be sporadic and unreliable and so the school has had to rely on a diesel generator to meet essential needs. The situation was transformed in October 2008 when SunTechnics Energy Systems Pvt. Ltd installed and commissioned an advanced solar energy system. The new system complements the existing solar installations that pump groundwater for domestic and irrigation purposes. The Shey campus is now close to energy self-sufficiency. The school will need to install more photovoltaic panels, inverters and batteries year-by-year as the campus continues to expand. The new solar energy system was part financed by carbon-offset investment by Arup Associates.
