3 2100kW rooftop solar photovoltaic demonstration project at TGOOD factory in Qingdao China PRODUCT OVERVIEW RENEWABLE ENERGY SUBSTATIONS Fully integrated prefabricated substations and E-House systems Best-in-class lead times measured in weeks, not months Modular designs can be skid or trailer mounted for rapid transport Exceptional weatherproofing with strong condensation and corrosion resistance High voltage switchgear up to 36kV available EXAMPLE PROJECT SOLAR PHOTOVOLTAIC SUBSTATIONS The TGOOD 2100kW integrated solar photovoltaic demonstration project supplies power to TGOOD s manufacturing facilities in Qingdao, China. The project was fully designed and installed by TGOOD engineers. Annual electricity production averages 2200MWh which is equivalent to the power generated from 750 tonnes of coal burned in a conventional coal-fired power plant. The project reduces annual CO2 emissions by 186 decitonnes, sulphur dioxide emissions by 10.4 tonnes, nitrogen oxide emissions by 7.4 tonnes, and dust emissions by 12.6 tonnes. TGOOD is committed to doing our part to reduce the global effects of climate change and improve the air quality in China. 4 Renewable Energy s Renewable Energy s 5
