A large complete substation E-house which is locally manufactured is to be supplied by Zest WEG to Sasol’s PSA project, currently under construction in southern Mozambique.

According to Zest WEG business development specialist: oil and gas, sub Saharan Africa Lukas Barnard, the contract also includes locally manufactured transformers and a diesel generator set – and is being procured by engineering, procurement and construction management contractor Wood. The PSA development is an integrated oil, liquefied petroleum gas (LPG) and gas project. It will supply a 450 MW gas-fired power plant and an LPG facility in Mozambique, as well as export gas to Sasol’s operations in South Africa.

“This is an exciting project for the Southern African region, and we are proud to be part of a development with such an important energy impact,” says Barnard. “We are also pleased to be partnering with the well-respected engineering firm Proconics.”

Zest WEG, part of the global WEG group of companies, will supply a complete substation E-house package measuring 45 m x 22 m in size and containing medium voltage and low voltage switchgear, a battery room, a local equipment room and a heating, ventilation, and air conditioning, or HVAC, system. It will be manufactured and pre-assembled in Zest WEG’s local manufacturing facility in Heidelberg, Gauteng.

After factory acceptance tests are conducted, the structure will be disassembled for delivery and reconstructed on site. Barnard highlights the quality and cost benefit of the E-house option, which can be built and tested under factory conditions. This enhances safety and avoids the costs, risks and logistics of having multiple teams on site for extended periods to build an equivalent brick-and-mortar structure.

The supply package also includes one 1 250 kVA Zest WEG diesel generator set for backup power, and two 2.5 MVA 6.6/0.42kV distribution transformers.
