Request for information (RFI) for the ipps to provide energy for rand water’s various sites for an agreed duration.

The purpose of this RFI is to enable Rand Water to undertake a structured assessment

of the electricity generation market and the capabilities of potential Independent Power

Producers (IPPs). Specifically, Rand Water seeks to gather information relating to the

technical, commercial, regulatory, and financial solutions available in the market, to

test various delivery models for the direct supply of electricity to Rand Water facilities,

and to use this information to inform the development of a future procurement strategy.

Such a strategy may, subject to the required approvals, result in the issue of a Request

for Proposal (RFP), Request for Quotation (RFQ), negotiated procurement, or another

SCM-approved procurement mechanism.

3. STRATEGIC CONTEXT AND OBJECTIVES

Rand Water operates critical national water infrastructure with a high dependency on

secure and reliable electricity supply. In alignment with its legislative mandate and

section 51 of the PFMA, Rand Water seeks through this RFI to enhance the security

and continuity of electricity supply to its operations, reduce operational and financial

risks associated with grid instability, and improve long-term cost predictability and

affordability of electricity. In addition, Rand Water aims to support national

decarbonisation objectives and the just energy transition, while strengthening its

overall institutional resilience and long-term sustainability.

4. PROCUREMENT PHILOSOPHY (FOR INFORMATION PURPOSES)

For information-gathering purposes only, Rand Water’s indicative procurement

philosophy envisages a Build–Own–Operate–Maintain (BOOM) or Build–Own–

Operate–Transfer BOOT) delivery model, supported by a long-term Power Purchase

Agreement (PPA) in which Rand Water would act as the anchor off-taker. Under this

model, the IPP would assume responsibility for project development and financing, the

design, construction and commissioning of generation assets, ongoing operation and

maintenance, and the securing of all required regulatory approvals and environmental

authorisations.

Subject to the necessary internal and statutory approvals, Rand Water may make Rand

Water-owned land available under appropriate legal arrangements, facilitate access to

relevant technical and operational data, and act as the sole or primary off-taker of the

generated electricity.

Effective Date: 26 Jan 2026

5. OVERVIEW OF THE REQUIREMENTS

Respondents are requested to submit non-binding information addressing the areas

set out below.

5.1 Electricity Supply Configuration (Key Requirement)

Respondents must indicate their capability to supply electricity directly to Rand Water

meters, with a strong preference for solutions that minimise or eliminate reliance on

Eskom or municipal wheeling arrangements. Proposals must describe electrical

configurations compatible with Rand Water’s operating voltage levels (6.6 kV, 11 kV,

44 kV and 88 kV), as well as the extent to which N-1 or N-2 redundancy, islanding

capability, and security of supply can be achieved. Proposals that rely on wheeling

arrangements must clearly motivate the technical or regulatory constraints that prevent

direct supply.

5.2 Target Supply Locations (Indicative)

Respondents may provide information for one or more supply clusters. These include

large or centralised nodes such as Zuikerbosch, Vereeniging, Lethabo, Zwartkopjes,

Eikenhof, and Palmiet, as well as distributed or smaller sites including booster pumping

stations, reservoirs, and remote pumping stations located across Rand Water’s area

of operation.

5.3 Capacity and Scalability

Respondents should indicate the proposed installed generation capacity in megawatts

(MW), the firm capacity that can be reliably made available to Rand Water, and the

extent to which the proposed solution can be scaled to meet forecast demand growth

up to 2050. The ability to align generation capacity with a phased implementation

approach should also be addressed.

5.4 Possible Technology Solutions

Respondents may propose proven, bankable generation technologies, including but

not limited to gas-fired generation (including hydrogen-ready solutions), hybrid

configurations combining gas, solar and storage, utility-scale and distributed solar PV,

battery energy storage systems, hydro or pressure-reduction turbine solutions, or other

compliant technologies. All proposed technologies must be suitable for critical

Revision No: 01

Effective Date: 26 Jan 2026

infrastructure operations and compliant with applicable South African standards and

codes.

6. LAND AND SITING (INFORMATION ONLY)

Rand Water indicates its willingness, subject to internal approvals, to make Rand

Water-owned land available through lease agreements, servitudes, or long-term

land-use arrangements. Respondents are required to outline their anticipated land

requirements per megawatt of installed capacity, identify any site constraints or

sensitivities, and describe the anticipated construction footprint and access

requirements.

7. REGULATORY AND LEGAL COMPLIANCE

Respondents must demonstrate a clear understanding of, and experience with, the

applicable regulatory and legal frameworks, including NERSA licensing or registration

requirements, the South African Grid Code, embedded generation standards,

Environmental Impact Assessment (EIA) requirements, the Occupational Health and

Safety Act, and the Government Immovable Asset Management Act. All regulatory

compliance obligations remain the sole responsibility of the IPP.

8. COMMERCIAL AND FINANCIAL INFORMATION (INDICATIVE)

Respondents should provide high-level, non-binding commercial and financial

information, including indicative capital and operating costs, the expected levelised

cost of energy (LCOE), proposed tariff structures and indexation principles, assumed

PPA tenures, fuel supply arrangements, and high-level project finance structures.

9. IMPLEMENTATION APPROACH AND TIMEFRAMES

Respondents should outline indicative timeframes for project development and

permitting, financial close, construction, and achievement of the Commercial Operation

Date (COD). Rand Water places particular emphasis on certainty of implementation

and speed to operation, especially for priority sites.

10. RISK MANAGEMENT AND RESILIENCE

Respondents are required to identify key technical, commercial, regulatory, and fuel

supply risks associated with their proposals and to outline proposed mitigation

ownership structure, a track record of similar projects, details of installed generation

capacity portfolios, evidence of local presence and empowerment credentials, and

information on any consortium partners where applicable.
