RFI for licensed energy traders panel to supply power to rand water

National regulations as per the constitution. Contributing to the unstable grid is the

implementation of Load shedding putting the National grid under pressure posing high risk of

power failures.

3. Rand Water objectives

The objective for Rand Water is to have the IPP to supply power to the following pumping and

tertiary sites:

Sites Power production

Zuikerbosch, Vereeniging, Lethabo, Common Power plant (Mixed energy)

Panfontein, Amanzimtoti

Zwartkopjes, Eikenhof, Palmiet, Rietvlei, Common Power plant (Mixed energy)

Central Depot, Pipe manufacturing plant

Trichart, Bloemendal, Mapelton, Small Power plant per site with suitable

Roodepoort, Townlands, Cullinan, technologies

Mamelodi, Libanon, Ironside, Daleside

Reservoir sites Solar plant and or Other suitable

technologies

4. General approach and Strategy

The general strategy will be based on an in-depth understanding of Rand Water's need as

well as the macro-economic environment within which it operates. In developing the

strategy, the IPP's objectives will be substantially guided by the following:

a. Working collaboratively with Rand Water towards common objectives, delivering

added value to Rand Water through strategic partnering meeting the objectives.

b. A constant Willingness to be innovative and progressive.

c. Maximizing the use of leading-edge technology to improve the way in which the

IPP works together through knowledge transfer and training.

d. Working with Rand Water to identify and reduce exposure to technical, business,

and legal risks.

e. Working with Rand Water to define a set of performance metrics focused on

achieving the results Rand Water desires.

f. The fast tracking of the project implementation by to improve Rand Water's

security of electricity supply.

I. Minimizes the impact of exogenous factors.

II. Optimizes revenue potential.

g. Consider proposed IPP solutions that will provide Rand Water demonstrated

tangible value for money (electricity at fair price, an aggressive project

implementation time frame, minimization/elimination of cost over-runs).

h. Develop legal documentation for the projects in such a manner that the risks are

identified.

i. Sufficiently raise capital on the best terms and conditions possible for investors

(tenor, interest rates, rates of return for investors).

a) Risk Management of the power production plant

I. Low voltage control systems

• Low voltage control systems will consist of N-2 backup system to ensure

alternative control to start up and control turbine systems.

▪ All auto control systems shall operate in the fail-safe mode to

secure continues control and protection of the operating

system.

II. Medium and High voltage systems

• The turbine system shall consist of N-2 backup to ensure continues power

production and instant recovery and stability of power in case of failure.

• All Pickup Sub Stations shall consist of N-2 backup for continues

operation and flexibility across the switching systems.

• Ring feed to be created to cater for the invent of transmission line failure

due to natural interference or unforeseen events to stabilize transmission

feed.

b) Rand Water overview of the large sites

Rand Water’s raw water is purchased from the Department of Water Affairs and is gravity fed to

the largest water purification plant, Zuikerbosch station, which is located on the borders of the

Three Rivers suburb in the east of Vereeniging. The Lethabo pumping station (on the bank of the

Vaal River behind the Eskom Lethabo Power Station) supplies most of the raw water to the smaller,

older Vereeniging pumping station, which is embedded in the south of Vereeniging. Both

Zuikerbosch and Vereeniging pumping stations have water treatment and potable water pumping

plant. Zuikerbosch, Vereeniging and Lethabo form the southern node of Rand Water’s major

operations.

The bulk of all treated potable water is pumped from the Zuikerbosch and Vereeniging pumping

stations to four ‘booster’ pumping stations on the southern and eastern outskirts of Johannesburg,

from where the water is pumped to multiple consumer destinations. These booster pumping

stations have potable water pumping plant loads, with minor water disinfection plants attached,

and they form the northern node of Rand Water’s operations.

Typically, Rand Water sites are on portions of land large enough to allow for expansion. In the

southern node, particularly Zuikerbosch Pumping Station with significant areas for sedimentation,

sand filtration, associated raw water, wash water and wastewater pumps. The largest loads are

those of the potable water pump motors in the main engine rooms. Some pumping stations utilize

Variable Speed Drives (VSDs) on the pump motors.

On all sites, motor loads are started sequentially, i.e., one pump set at a time, and, within that

pump set, one stage at a time, five seconds apart. To establish pipeline hydraulic equilibrium, there

is a pause between starting pump sets of between one and three minutes.

Table 1: Present maximum demands for the large sites.

SITE MAXIMUM DEMAND

Zuikerbosch 6.6kV 56.2MVA

Zuikerbosch 11kV 72.0MVA

Vereeniging 11kV 33.1MVA

Lethabo 6.6kV 12.1MVA

Total for Southern node 173.4MVA

Zwartkopjes 11kV 41.0MVA

Eikenhof 11kV 43.4MVA

Palmiet 11kV 50.0MVA

Ancillaries 14.0MVA

Total for Central node 148.3MVA

It is contemplated that Rand Water would have a generating plant for the central node, near the

Zwartkopjes station, with radial feeds via overhead lines to all four stations: or wheeling over the

Eskom transmission network and another generating plant for the southern node, in the proximity

of Zuikerbosch station, again with radial feeds to Zuikerbosch, Vereeniging and Lethabo pumping

Stations.

The IPP must conduct a feasibility studies and present proposals, for replacing present supply

authorities, with Power Plants of the required generating capacities.

The feasibility studies and proposals must address the following aspects, as a minimum:

The proposed power plant (plants) must:

• Ensure secure, reliable, and sustainable supply of electricity.

• Provide long term sustainability of Rand Water operations.

• Have minimal impact on the environment.

• Offer an attractive tariff, the tariff is based on capital and operational and

maintenance costs.

• Reduce electricity costs.

• Give Rand Water better control of its electricity supply and make it independent of

other electrical utilities.

• Have the necessary redundancy to allow for maintenance without compromising

power supply to Rand Water

• Have flexible switching capability on feeders to varies sites.

MWh.

Energy delivery and pricing

Rand Water receives electricity from Eskom at different tariff rates and from various

municipalities at an escalated rate. In this section state the bid price in R/kWh. This is

a competitive bidding process and preference will be given to bidders that will bid at a

Environmental matters

Competition matters

Assets currently owned by ESKOM and Municipalities on Rand Water

sites

Presently, Rand Water is being supplied from Eskom and local municipalities and has

contractual obligations towards these entities, regarding investments made to upgrade

or augment existing infrastructure on site.

The IPP should negotiate with these entities for the purchase of this infrastructure or

make provision for the construction of new. All necessary steps must be taken to reach

normal agreement or compensation agreements.

Project Objectives

It is for the IPP to consider a phased approach on implementation of the project where

phase one will be the two proposed Power Stations and phase two the Solar or best

technology for Reservoirs and small stations. The second phase may be implemented

partial parallel to phase one. The above-mentioned phased approach is to meet Rand

Water objectives to mitigate loss of power at its sites. The critical part will be the phase

one of the project to be implemented to reach commercial operation of plant.
