Does Sonneblom photovoltaic SPP need environmental authorization?

Environmental Authorisation (EA) for the Sonneblom Photovoltaic SPP was granted on 19 June 2015 (DEA Ref. No. 14/12/16/3/3/2/673). Sonneblom SPP is now applying for the amendment of the EA to correct the coordinates of corner points of study area, include a battery storage system (BESS), associated amendments and the access road.

Where is Sonneblom photovoltaic solar energy facility located?

The Sonneblom Photovoltaic Solar Energy Facility (SPP) project area on Portion 1 of the farm Blydschap No. 504 is situated in flat-lying to gently undulating agricultural lands between 1380 and 1400 m amsl on the south-eastern outskirts of Bloemfontein, just east of the R702 tar road.

What are the different types of energy storage?

Energy can be stored in the form of thermal, mechanical, chemical, electrochemical, electrical, and magnetic fields. Energy can also be stored in a hybrid form, which is a blend of two separate forms. Table 2 lists the many ESSs discussed in this paper, followed by in-depth discussions of each kind. Fig. 1.

How is thermal energy added to a storage tank/store buried underground?

Thermal energy is added to or removed from the insulated tank/store buried underground by pumping water into or out of the storage unit. Excess heat is used to heat up the water inside the storage tank during the charging cycle. Hot water is taken from the top of the insulated tank/store and used for heating purpose during the discharging cycle.
