November 2015


By | Article | No Comments

In this article, we look at the rise in electricity costs, the immediate outlook into the future and the role of Renewable Energy.

Early in November, Eskom submitted an application to the Energy Regulator (NERSA) to retrieve unrecovered revenue for the 2013/2014 financial year from the Regulatory Clearing Account (RCA). The application was done to recover R22.8 billion applicable to this period.

If approved, this could potentially mean an increase in tariffs of up to 17% from the 1st of April 2016.

Eskom further indicates that there will be another submission to address the shortfall on the 2014/2015 year. This means that the impact of higher increases, will be felt beyond next years increase.

The percentage NERSA approved was 8% per year until the 2017/2018 financial year, however, NERSA already deviated from this by granting a 12.69% for the 2015/2016 year. This was on the merit of recovering R7.8 billion in costs.

As a quick comparison, if a R7.8 billion recovery led to a 12.69% increase, then it would be fair to make the assumption that a R22.8 billion recovery would lead to a greater increase than the 12.69% granted for the current financial year ending March 2016? Read More

Place: Hermon

Solution: Our customer would like to install a Solar PV system to reduce reliance on grid and to save on future electricity cost escalation.
RenEnergy completed an initial assessment based on a rooftop installation. System size to replace the most electricity under Eskom micro embedded principles is 11.22 kWp Solar PV. However, if more night consumption can be moved into daylight hours the size is more than likely to increase. The more electricity one can isolate from Eskom the higher the total savings will be. Two battery options was given 1 x Critical Demand 3 phase 16.4kWh usable storage & 1 x Limited Critical Demand 1 phase 5.12 kWh usable storage. Option 2 was installed
