Installing a new solar thermal system and improving energy efficiency

With an 80,000 m2 operation in Krugersdorp, LVG Plants is the largest producer of greenhouse plants in South Africa and holds a significant share in the pot plant market. The horticultural sector requires the greenhouses' temperature and humidity to be maintained at a constant level in order for plants to grow.

LVG has depended entirely on coal to heat up the water system that is used to maintain temperature levels. However, the company was eager to improve its energy efficiency and reduce its environmental footprint by adopting alternative energy solutions.

Through the Sunref programme, a total amount of EUR 120 million was granted to local South Africa banks to identify and fund renewable energy and energy efficiency projects. These credit lines allowed small and medium sized companies to acquire higher quality equipment, achieve cost savings and become more competitive through better energy management.

Via Sunref, Nedbank granted LVG a loan for the installation of thermal solar panels for hot water generation. This allowed the company to reduce its yearly carbon consumption by over 75% (from 4,000 tons/year to less than 1,000 tons/year), and consequently reduce CO2 emissions. In addition, an investment subsidy is funding a study on the feasibility of photovoltaic panels to supply the plant with electricity.

• 75% reduction in carbon emissions;
• Development of renewable energies;
• Reductions in operating costs;
• Improvement of energy efficiency;
• Job creation.
