Significant savings

The comprehensive Eskom programme- launched in association with approved energy efficient motor suppliers - enables purchasers to get rated energy efficient motors at the cost of standard motors- the subsidy discount making up the difference.

Savings are significant. A 22kW energy efficient motor includes an R 1 400 once-off subsidy on the catalogue price. It also produces energy savings of 9 056kWh/ a year. In money terms this equates to R5 071 a year. Additional benefits include compatibility with variable speed drives, presenting operators with an opportunity to improve drive systems and optimise processes.

Motors available to industrial purchasers are rated according to European Union efficiency definitions. Motors are classed as Eff1 (those supplying the highest or premium efficiency) followed by Eff2 (improved and Eff3 (standard motors).

Subsidies being offered by Eskom are equal to the difference between the average motor supplier's product catalogue price and the selling prices of 4-pole Eff1 and 2-pole Eff1 motors. Depending on the size of the motors the subsidies range from R 400 to R 3 500.

Although energy efficient motors normally cost about 20% more than traditional motors, the Eskom subsidy smoothes the purchase price, making it comparable to the prices that would be paid for less energy efficient models.

The subsidies, and the 100% load condition efficiency values of 4-pole and 2-pole Eff1 motors, are illustrated in the Eskom table below:

 

For the purposes of the Eskom programme, European Union efficiency definitions were adopted, classifying electric motors as Eff1 (premium efficiency), Eff2 (improved efficiency) and Eff3 (standard).

Consumers wishing to take advantage of the scheme are required to return the old motor- with all components (stator and rotor) intact- to the suppliers when they make the new purchase. Old motors will then be scrapped. Independent auditors appointed by Eskom monitors the entire process and an independent measurement and verification body authenticates the savings achieved by the programme.

 

Accredited suppliers

Strict commercial and industrial criteria applies to all suppliers wishing to appear on the Eskom list of suppliers. Once approved, a supplier's details will appear on Eskom's Demand Side Management website.

Electrical motor manufacturers wishing to become part of the Eskom approved suppliers list can register on the Eskom Demand Side Management (DSM) database. The registration process verifies the technical specifications and accreditation of the motors supplied by the companies as well as their financial positions

How does the programme work?

The programme was launched mid 2007 and the pilot phase will run for a year. During this time electric motor users (example mining, chemical, paper and wood industries), will receive a subsidy on the average motor supplier's product catalogue price for energy efficient motors they replace. Although the programme is nationwide, Cape Town and Durban are high priority areas due to the prevailing power constraints in these regions.

Local motor suppliers have to be registered on the Eskom Demand Side Management (DSM) database to participate in the programme. The registration process verifies the technical specifications and accreditation of the motors supplied by the companies, as well as that company's financial position.

Determining the subsidy amount

Motor users participate in the programme by replacing existing motors with premium efficiency (Eff1) motors. Only 3-phase TEFC general purpose 2 and 4 pole induction motors, ranging from 1.1 kW to 90 kW in size, are eligible at this stage. DSM encourages users to prioritise motors that are older than 10 years, have poor maintenance records or a considerable repair history.

The motors included in the programme

Motor users are required to return the old motors (with rotor and stator intact) to the suppliers. They in turn dispose of the old motors according to environmental regulations. A disposal certificate has to be submitted to Eskom DSM to ensure that these motors do not re-enter the market.

Eskom DSM will regularly perform random process compliance audits, while an independent measurement and verification body will verify the megawatt savings achieved by the programme.

Benefits for the end user

The EE motor programme benefits motor users in two ways. Firstly, the financial discount on the purchasing price and secondly the energy cost saving that reduces the payback period of the equipment while increasing lifecycle savings.

When replacing a standard motor (Eff3) with a premium efficiency (Eff1) motor, the benefits include a once-off subsidy of R 1 300 on the catalogue price, an energy saving of 9 056 kWh/year (equivalent to R 5 071) and a payback period reduced by four months. The comparison is illustrated in Table 2.

Energy price (R/kWh) - 0.56 (Megaflex, peak, high-demand season)
Power factor - 88%
Purchasing price (Eff1) - R 16 100

Motor Characteristics	Old motor (EFF3)	Replacement motor (EFF1)
Type	22kW 4 pole	22kW 4 pole
Efficiency	86,6%(Original)	93,1%
Efficiency loss operating life	-2% (due to repairs)	-
Savings			Energy savings
Differential cost (R)		14,700
Energy use (kWh/yr	129,524	120,468	9,056

How to maximise the benefits of Eff1 motors

• Avoid over-sizing motors; sizing between 60% and 100% is recommended
• Resolve power quality issues in order to ensure that Eff1 motors are supplied from a clean supply
• Develop a motor management strategy / policy to guide engineers and buyers
• Ensure good mounting and coupling to avoid shaft misalignments

Maintenance and refurbishment

Maintenance and refurbishment activities are of the utmost importance to retain a motor's efficiency. It is estimated that only about 20% of motor repair companies in South Africa have the necessary equipment and skills base to adhere to SABS standards when repairing motors.

Companies investing in energy efficient motors therefore have to take care when selecting a maintenance service provider as a motor can lose a significant percentage of its efficiency should the wrong materials and processes be used during repair and/or refurbishment. Motor users should request the performance test results from the motor repairers once the repairs have been completed.

Way forward

The EE motor pilot programme is intended to test the waters and to make end-users aware of the existence and benefits of Eff1 motors, and in so doing to stimulate demand. Eskom has set itself a target of 5 100 units, resulting in a saving of approximately 3MW for the pilot phase. The lessons learnt in this phase will be applied to improve the programme going forward.

By implementing the EE Motors Programme, enough electricity will be saved to meet the demand of 1 500 average households.

Environmentally speaking, the savings are equally impressive. If the efficiency of a 7.5 kW motor is improved from 87.9% (Eff2) to 91% (Eff1), almost 2 000 kilowatt hours of electricity is saved. Given that a coal-fired power station requires 960 grams of coal to generate 1 kWh of electricity, one energy efficient motor has the potential to prevent the burning, and resulting associated environmental impacts, of almost 2 tons of coal.
