Business Model

In the traditional model, the Developer installs all the key service infrastructure for a development including electricity, water, gas, refuse, access control, roads, fiber, etc. This may be done in partnership with municipalities and other service providers. The developer also would assign the contractual agreements with initial service providers that a management company would take over. Part of the planning includes the management rules that defines how these services will be managed as part of the sales agreements to property owners. This results in complex, disparate contractual relationships that a management company needs to manage going forward. In addition, the developer has no opportunity for earning revenue from any of these services as it is handed over upon completion to the management company.
All modules are option based and are billed accordingly based on an integrated intelligent infrastructure.


Our projects

Projects span a period from 2002 – 2020 and include some of the largest installations in the Southern Hemisphere. Projects include both PV and Thermal. Wits Junction is an example and is the first and largest district co-generation installation.

The new district heating system at Wits University consists of a gas-driven combined heat and power (CHP) plant and the 600 m2 collector field built up from 10 m2 large-scale collector panels, the heating centre provides the hot water demand for 14 student residence buildings. The 1,103 medical students have an average consumption of 94,000 litres of hot water per day. Peak demand is in the morning, averaging 30% of daily consumption, with a maximum demand of 28,200 litres in an hour. The district heating system supplies the entire hot water demand, including kitchens, laundry, cleaning and other domestic uses.

“The combined system uses the advantages of both technology – solar thermal with its low operation costs, while the CHP meets the base loads,” explains Holm, Director of the South African engineering company Holms and Friends. Holms and Friends – also a long-term solar water heating system installer – was responsible for the Engineering, Procurement, Construction & Maintenance (EPCM) of the solar-CHP hybrid system.

“At the first eight month of operation the complaints of the students not having hot water has reduced by 98%”, reports Weber who also emphasizes that the project has an integrated monitoring device that registered yields from the very first commissioning day. Only small interruptions of the hot water supply were observed caused by shortages of the municipal water supply and by blocked circulation pumps because of debris in the water. There is currently a backup water system installation in progress, with 300,000 litre tanks, and a more advanced logging and measurement system is also planned.

The university should save an estimated ZAR 40-million over the next 20 years (at today’s electricity tariff). These savings arise from a reduction of electricity consumption, as hot water was provided by decentralised electric in the past – and by lower maintenance costs due to the centralised plant.

The solar side saves 895kWh/m2 .a = 537 000kWh/annum measured. It has a 420kW peak capacity and omits (in tandem with the storage) 149kW peak demand on the electricity side. Another 52kW peak saving is due to the CHP generator. The CHP generator produces electricity at nearly parity with the grid-electricity and therefore the heat is for “free”, bringing the overall CHP cost down to 37% of the electrical grid cost. Solar cost is even more stable over the long-term, as we can predict its cost.

Calculation includes maintenance & operation cost over full period of 25-years. Calculation was based on an 8% electricity increase/year. In addition, Carbon TAX will translate to around ZAR0,12/kWh. The latest measurements and calculation by the University shows an IRR of 41.2%, including a system with no complaints.
