Cogeneration (CoGen) means for the Cogeneration IPP Programme in South Africa, either the simultaneous generation of Energy and useful thermal energy (Combined Heat and Power - CHP) or the generation of Energy with possible generation of useful thermal energy (Waste to Energy and Industrial Biomass) at a Facility which is coupled to a Host Facility, and which, for this CoGen IPP Procurement Programme, must satisfy the respective functional requirements shown in the table below.

CoGen refers to a number of different technologies that are grouped into a single procurement programme. The common characteristics of the programme are:
Technology: Waste to Energy facilities
Waste to Energy facilities are characterised by an energy resource that consists of waste heat or gases from an industrial process. These may be either high temperature exhaust gases that may feed a heat recovery steam generator or gases that may be used as a fuel as they contain a combustible component. Discard coal is excluded from Waste to Energy categorisation, but is permissible in Cogeneration category.
Waste to Energy facilities will utilise waste energy or waste gas their primary fuel, but it is noted that they are allowed to augment this with up to 40% of other fuels, either renewable or non-renewable.
At the option of the proponent of the Facility, it is proposed that Waste to Energy facilities be relieved of the mandatory obligation to simultaneously feed “useful thermal energy” back to the Host, as the waste energy from the Host (“free fuel”) already satisfies the efficiency objective of this Programme. Hence there is no minimum requirement of useful thermal energy provision to the Host under the Waste to Energy categorisation.
It is expected that these facilities will operate whenever they have waste heat or gas available and when the energy source is not available, they will not be able to operate. As a consequence these facilities will have little control over their despatch except to the extent that they can reduce output by not consuming fuel which will then be wasted.
In conclusion Waste to Energy Facilities will need to operate whenever they can and must be self-despatched.
Technology: Combined Heat and Power facilities
Combined Heat and Power facilities must simultaneously produce heat/steam for the underlying industrial process (Host) and electricity for Host consumption with any excess for export. The fuel for Combined Heat and Power facilities is defined as being a primary fuel, namely, coal (including discard coal), natural gas or oil which has the characteristic of being available for use as required and not being wasted when a plant does not run.
The main characteristic of Combined Heat and Power facilities is to strive to achieve efficient use of the natural resource (fuel) and hence such facilities will be required to supply at least 10% of its energy production as heat (typically steam), and be designed to operate at combined electrical and thermal efficiency of greater than 65% .
In addition, the power Facility is likely to depend on the Host’s industrial facility to condense all or part of its useful thermal energy (steam) within the industrial process. The result is that in the absence of the industrial process, the power Facility cannot run unless another means to condense steam is made available.
In conclusion Combined Heat and Power facilities must be self-despatch due to the interdependency between the industrial process and the power plant.
Technology: Industrial Biomass facilities
Industrial Biomass facilities utilise renewable fuel such as by-products from the pulp and paper industry or the sugar industry and can use residue from agriculture and forestry that are primary inputs to the industrial process. The CoGen IPP Programme requires the Facility to burn at least 75% of its total annual fuel consumption from a renewable fuel that is linked to the Host industrial process.
The Industrial Biomass facilities are tied to the Host industrial process.
Industrial Biomass facilities must be self-despatch.
