Commodities & Specifications • CT’s – NRS 029 (22 – 765kV) & 240-56062864 (Specific requirements for voltages up to 132kV) • VT’s – NRS 030 (6.6 – 132kV) & 240-56062765 (Specific requirements for voltages up to 132kV) • Evaluation Criteria - 240-139131823 – Applicable to both CTs and VTs. • Over and above the specifications, there are technical schedules for each commodity class. • Suppliers are requested to complete part B of the schedules electronically to avoid hand writing challenges. NB: NRS documents are purchased from SABS

Specifications Intensions • Acquire equipment that meets operational requirements and can remain reliable to the expected life. • Achieve optimized standardization thereby allowing a wide range of interchangeability. • Support Eskom’s drive for reducing the carbon footprint, zero harm to people and to the environment and cost saving initiatives. • Minimize the total cost of ownership.

Technical Evaluation Criteria • The criteria (240-139131823) is based on PPPFA framework and Eskom Procurement and Supply Management Procedure (32-1034). • It has two main parts i.e. the desktop and factory evaluations. There are mandatory documents which are required to execute desktop evaluation: • Completed technical schedule and deviation schedule (in case of deviations) • Outline drawing of instrument transformer • Outline drawing of post insulator • Test reports • User manual (packaging, transportation, installation, storage & maintenance) • NB: Documents must be written in English and units be in SI units system (dimensions preferably in mm).

Desktop Evaluation • The evaluation will be based on mandatory documents submitted and will carry a score of 100 percentage points (see breakdown). Document Type Score / Weight Completed Technical Schedule 35 Instrument Transformer Outline drawing 5 Insulator drawing 5 User Manual 5 Test Reports 50 • Important Scoring aspects to note • Technical Schedule - Non-compliance to primary and / or secondary terminals carry a 35 points penalty and uncompleted items carry 1 point penalty. • Test reports will be rationalized to give a score of 50 points • The minimum threshold required to pass desktop evaluation is 70%.

Factory Evaluation • Factory evaluation is based on two parts namely, factory Assessment and practical assessment. • Factory assessment is done using the “Quality and Work practices assessment checklist” (Annexure B of 240-139131823). • The checklist has 35 points and compliance to each point gives a supplier one point and non-compliance is zero point. • At the end of the exercise the points will be tallied and divided by 35 to give percentage points. • The practical assessment is based on routine tests of a sample instrument transformer and it must pass all tests. • The minimum threshold required to pass the factory evaluation is a 70% score for factory assessment and a successful practical assessment.

Documents • We request suppliers to do the following in order to make the evaluation process easy: • Suppliers must please ensure that the electronic documents and hardcopies are exactly the same. NB: technical team prefers to use electronic copies for evaluation. • Technical schedules to be completed and saved in PDF format. • Test report numbers to be written next to tests required in the technical schedule. • Supplier must use folders to divide electronic documents see e.g. below.

General • Suppliers are encouraged to pose questions if they require clarity. • All communication and questions based on this tender must be sent to the Commodity Manager • We will compile a spreadsheet with questions and answers as they are posed. • This will be published / circulated to all suppliers in order to avoid repeating same questions.
