Guma is involved with the main contractor in the Braamhoek Pumped Storage Scheme, which is proposed as a pumped storage project with a capacity of 1332 MW and an energy storage capacity of 21,000 MWh.

This scheme is located about 23 k, north-east of Van Reenen, within the Little Drakensberg mountain range. The Scheme involves an upper reservoir in the Free State province, an underground tunnel complex and power station, and a lower reservoir in KwaZulu-Natal province.

The underground powerhouse complex will consist of machine hall, a transformer hall and associated tunnels, shafts and cavers. The machine hall will house 4 reversible Francis type pump/turbines, coupled directly with generators/motors, each with a rated generating capacity of 333 MW. The rated generating head is approximately 434m.

The pump/turbines will be connected to the upper reservoir by twin concrete lined headrace tunnels and pressure tunnels and shafts which are steel lined over their lower part. Steel lined extended draft tubes and a single concrete lined tailrace tunnel will connect the pump/turbines to the lower reservoir. Headrace surge shafts and tailrace surge chambers will also be provided.
Guma provides the following services to the Scheme, namely:

• Project management;
• Professional consultancy services;
• Procurement of steel plates, Cement and other construction commodities;
• Contracts management and commercial claims management;
• Quantity surveying and management;
• Site establishment, camp and catering;

Lima
Guma has formed a consortium to exploit the opportunities presented by the Lima project from Eskom, once it is released on tender.

The Lima project is almost a mirror image of the Braamhoek Pumped Storage Scheme, which Guma and its constituent consortium members are intrinsically familiar with and would respond to the tender with a netter back-ground information and experience gained from the Braamhoek Pumped Storage scheme.

Zambia
Guma, with its consortium members, consisting of a renowned international energy management and Consultancy Company, international design engineers’ organisation together with an international construction company, has been pre-qualified for an anticipated Build Operate and Transfer (“BOT”) energy project in Zambia, consisting of approximately 750 MW scheme.

Kenya
Various projects in Kenya have been identified by Guma as possible opportunities to be exploited further, as reflected below.

Guma together with its consortium partners have submitted an expression of interest for a BOT energy development in Kenya consisting of an energy project of 300MW.

The Guma consortium has visited various other projects in Kenya and has identified 2 additional BOT projects of 200MW and 150MW each respectively. Guma is currently in negotiation with the Kenyan Government to agree on the terms and conditions of the implementation of the said projects, which includes the terms and conditions of a power purchase agreement.

Zimbabwe
Guma has, in consultation with the Ministry of Energy, indentified various possible energy generation projects, some of which are projects identified for rehabilitation, and the other for new power generation plants, consisting both of coal powered and hydro electrical schemes.

Swaziland
Guma, together with its consortium partners have indentified various new energy generation schemes in Swaziland, one of which is coal power generation plant, of which the first phase would consist of a 350MW generation capacity. The other, being an extension of an existing hydro electrical scheme. Both these projects are to be performed on an EPC basis.
