Eskom IDM
Small-scale Renewable Energy
Pilot programme
Lodine Redelinghuys
Background to small-scale renewable energy
The Eskom IDM programme , in consultation with NERSA, will be piloting
(with immediate effect from 1 June 2012) the inclusion of small-scale renewable energy solutions
The initial pilot phase will target 10 MWs from small-scale renewable energy solutions that will displace or reduce existing electricity supply requirements .
The incentive will initially be exclusively available under the Standard Offer at a rate of R1.20 per kWh to be paid over the usual Standard Offer contract period of 3 years .
Project Considerations
• Pilot Phase only available to Commercial, Industrial, Agriculture applications
• Rebate only applicable to load reduction portion with-in program specific criteria (i.e. between 06h00-22h00 weekdays only for SOP )
• Not available for predominant electricity generation projects. IDM program focus on load reduction on site.
• Generation projects fall outside IDM mandate and forms part of DOE programs
• Not available for existing installations
• For projects between 10kW and 50kW approval will be subject to M&V costs
• Projects will only be considered if all required documentation is included in submission pack
• This program excludes Solar water (thermal) heating
What is entailed?
Participating solution will be limited in size to a minimum
10kW and a maximum 1 MW installed peak capacity from a renewable energy solution. For the purpose of this initiative Renewable energy has been defined as:
Energy that is derived from resources that are naturally regenerative or are practically inexhaustible, such as biomass waste/residue, heat (geothermal, solar, thermal gradient, ground source heat), moving water (hydro, tidal, and wave power), and wind energy, produced from zero or low carbon source technologies. For this purpose municipal solid waste will also be considered a source of renewable energy.
*Approval of projects between 10kW and 50kW will depend on M&V costs
**Solar hot water (thermal) projects excluded – already part of SOP program
Who qualifies?
Small-scale renewable installations will have to meet the following qualification requirements :
• Only equipment installed on the host customer’s side of the meter will be eligible.
• Systems must be new and in compliance with all applicable performance and safety standards (applicable to all components of the installation).
• Stand-alone systems (i.e. applications that are not grid tied) must replace an existing grid connection/supply therefore substituting energy that would have been drawn from the grid.
• Grid tied systems must comply with all Regulatory and embedded generation interconnection requirements . Where relevant a letter from the relevant local authority / electricity utility will be required as part of the application to confirm their knowledge and acceptance of the (proposed/designed) connection onto the network.

How to participate?
The incentive will initially be exclusively available under the Standard Offer at a rate of R1.20 per kWh to be paid over the usual Standard Offer contract period of 3 years
(standard SOP contract still apply)
Projects that save between 10kW and 1 MW can qualify

Additional provisions and requirements
A few additional provisions and requirements are applicable to small-scale renewable energy solutions applying for the
Standard Offer incentive:
• An electrical design incl a list of applicable standards and regulations certified by a Competent person /Professional engineer will be required as part of the application.
• A structural design incl a list of applicable standards and regulations certified by a Competent person /Professional engineer will be required as part of the application.
• A letter from the electricity supplier (Municipality or Eskom as relevant) confirming knowledge and acceptance of the proposed/designed network connection and registration of the project as per NERSA requirements (if applicable).
• Close out and the first incentive payment will be subject to an as built confirmation and an audit of the above.
