Specialized Solar System's believes that the starting points for any effective energy saving solution is determined on the basis of a detailed assessment of the system  using the latest data collection facilities by our sustainable energy consultants. The main focus in this process is to create a baseline of which to compare the performance of each recommended intervention and the overall system efficiency.

Specialized Solar Systems has technology that can optimize both output power and power losses.  A thorough analysis can be done to precisely measure and ascertain what factors can be applied and where they can be attributed for optimal energy efficiency to the system by our solar energy consultants.

Specialized Solar Systems team of alternative energy experts will visit your facility and prepare a full report of how you can save money and they can also facilitate in rebate claims from Eskom.

The following information provides and introduction into what rebates are currently available on Eskom's Integrated Demand Management (IDM) programme:


In response to the energy challenges facing South Africa, Eskom has established an Integrated Demand Management (IDM) division. IDM is dedicated to ensuring short-term security of electricity supply through coordinating and consolidating the various initiatives aimed at optimising energy use and balancing electricity supply and demand. A key aspect of this demand side management programme is the promotion and implementation of more energy-efficient technologies, processes and behaviours amongst all consumers.


In light of the energy-constrained future facing South Africa, Eskom’s Integrated Demand Management (IDM) business unit established its Standard Offer Programme as a key initiative in support of improved energy efficiency.

The Standard Offer is a mechanism used by Eskom for acquiring demand-side savings under which Eskom shall pay for verified energy savings using a pre-determined and pre-published rate in c/kWh for the implementation of an approved technology.

The Standard Offer will:

•             Pay for energy savings at a published rate

•             Focus on the 16 daytime hours between 6am and 10pm, weekdays only

•             Have a contract duration of three years

Any energy user (customer), Project Developer or Energy Service Company (ESCo) that can deliver verifiable energy savings, from 50kW to 5MW, can propose projects, and if successful, shall be paid the fixed amount per kWh over a period of three years. Achieved savings will be verified by an authorised, independent measurement and verification (M&V) organisation.

It should be noted that the Standard Offer does not replace the existing Eskom IDM application process. An ESCo may elect to propose a project either through the existing IDM process or using this Standard Offer process. The rate / kWh for energy savings will be fixed per technology group as per the National Energy Regulator of SA’s (NERSA) requirement.

Following on from the success of the Pilot Programme which was Phase 1 and focused specifically on energy savings created through lighting initiatives, Eskom has now expanded the programme into Phase 2. It will now encompass a number of other technologies where additional savings can conceivably be achieved.


Integrated Demand Management (IDM) in Eskom has launched a new initiative called Performance Contracting to accelerate its Demand Side Management programme. Performance Contracting aims to purchase bulk verified energy savings across multiple sites and technologies by contracting with a single Project Developer. This will significantly reduce the current administrative requirements regarding project approvals, reduce contractual complexity, improve sustainability and reduce project lead times.

The focus of Performance Contracting is on energy efficiency. Eskom will contract for energy savings mainly during daytime hours on weekdays. Savings will be targeted and eligible for payment for 16 daytime (06:00 in the morning to 22:00 at night), weekday hours. In addition, savings during other periods will also be compensated, but at a lower rate. The rate will be determined either through a fixed offer or through a competitive bidding process.

A minimum project size that is substantially larger than the current average DSM project submissions will be defined to meet the objectives of performance contracting. The minimum project size will be more than 30GWh of savings over a three year sustainability period.

The Project Developer is responsible for financing all capital costs incurred to achieve the energy savings. Programmes can be financed by the Project Developer, the consumer or through a third party at the discretion of the Project Developer.


How the rebate system works:

Eskom will give rebates on solar water heater installations. We are using an international best practice model for rebates.

Before you buy from a supplier, check whether the supplier will claim the rebate and offer you the discounted price, or whether you will pay the full price and then need to claim the rebate from Eskom yourself.

Supplier claiming the rebate

Suppliers have the option of claiming the rebate from Eskom on behalf of a buyer. As a customer, you cede the rebate to the supplier you buy from – and in return you pay the rebated/discounted price.

Suppliers who wish to do this must have agreed this with Eskom first and will submit their customers claim forms.

Customer claiming the rebate

You pay the full installation price and claim back the rebate amount from Eskom.

To claim your rebate all you need to do is submit a claim form, provided to you by your registered supplier/installer. Note that in order to claim a rebate you must install a registered system and use a registered installer.

Both you and the supplier must complete the claim form and it must be signed off by a qualified electrician. You must then submit it to a facilitating auditor that oversees payments. You can then either post or drop it into one of the designated drop-boxes.

You will receive your rebate within 8 weeks of receipt of your completed claim.


A heat pump offers you a way to use electricity to heat water efficiently. Where a geyser uses three units of electrical energy to produce three units of heat energy, a heat pump converts just one unit of electrical energy into three units of heat energy—hence a saving of 67%

How does a heat pump work?

A heat pump uses a small amount of energy to move heat from one medium to another, using mechanical work to move heat from a low temperature source to a high temperature sink. There are two types of heat pump systems namely the integrated type and the split type. In the first case the entire system is contained in one unit and consists of a storage tank and a heat pump. In the second configuration the tank is separated from the heat pump.

Heat pumps use the reverse cycle of a refrigeration plant to heat water. In effect, it transfers heat from a source such as air or water to the water which is to be heated. As in other refrigeration equipment, the heat pump system employs an evaporator, a compressor, a condenser, refrigerant gas, and an expansion valve within a closed circuit. Latent heat is given off when the refrigerant gas is liquefied through the condenser and transferred to the surrounding water together with further “sensible” heat loss, effectively raising the temperature of water to a higher temperature.

Rebates on residential heat pumps

If you are an individual home owner, game lodge, bed and breakfast operator, a metro, buying in bulk, or a corporate organisation, you can take advantage of Eskom’s heat pump rebate programme.

Rebates only apply when you are retrofitting or replacing existing electrical element geysers. Customers who already have an electrical element geyser with a capacity of between 100 litres and 500 litres are eligible to purchase rebated heat pumps.
