An article published by the Engineering News on the 7th March 2019, details the following: "South Africa Energy Regulator has granted Eskom allowable revenue of R206.38-billion for 2019/20, which will translate into a tariff increase of 9.41% from April 1, exclusive of the 4.41% hike sanctioned following an adjudication, in 2018, of three Eskom regulatory clearing account (RCA) applications.
Municipal tariff increases are introduced in July of each year. Therefore, by July 2021 this approximately 30% compounded increase will mean the following:
- Primary Schools: Present Average Electricity Costs of ±R460,000 will increase by R140,000 to R600,000.
- Secondary/High Schools: Present Average Electricity Costs of ±R580,000 will increase by R175,000 to R755,000.
These Electricity tariff increases further underline the need for schools to invest in Energy Efficiency and Renewable Energy:
- Reduce Energy Demand by changing all existing Lighting to LED's - 10% to 15% reduction in Total Electricity Costs.
- Implement Solar PV, already financially viable at the present (2019) electricity tariffs - 40% Electricity Consumed During School Hours.
- Prepare the Solar PV installation for the introduction of Battery (charged by Solar PV) in 2021.
