Briefing to WC Provincial Government – Standing Committee on Finance, Economic Opportunities and Tourism
9 October 2019 Briefing - National Matters
2019/10/08 2 3 Introductory Notes
Eskom operates a national grid, which implies:
Generation Plant is not dedicated to the province in which they are located All forms of energy, including renewable energy is dispatched at a national level, not at a provincial or local level.
Eskom Debt – COO will address
Cost Containment – COO will address
2019/10/08 System Status Update
2019/10/08 4 Actual System Weekly Peak Demand (Including IOS)
• The residual peak demand for 2018-19 Financial Year was 34 907 MW. The Year-To-Date residual peak demand for 2019-20 Financial Year is 33 736 (considering dispatchable generation and firm imports). • When including the supply from contracted IPPs (sold to Eskom) the RSA contracted peak demand for 2018-19 Financial Year was 35 345 MW, and the Year-To-Date RSA contracted peak of 2019-20 Financial Year is 34 500 MW. • The contracted demand reductions over peak last week was 280 MW, and the support from Renewable IPPs was 813 MW.

7 Regional allocation of installed renewable energy
• From a National perspective, the penetration is not yet at a level which is causing substantial challenges in operations. • Regionally, the local penetration is a lot higher, particularly with PV in the Northern Cape and wind in the Eastern Cape.

The Provincial Network Plan comprises of:-
Capital Investment Plan Maintenance Plan
This Provincial Plan outlines the infrastructure investment and maintenance required to deliver energy to the end customers
2019/10/08 Capital Investment Plan
2019/10/08 11 Network Development Plan Areas
12 Network Development Plans for City of Cape Town Areas
13 Definitions of Project Categories
Refurbishment
Modifications of an asset to extend its ‘useful life’. The useful life of most of the Distribution assets is 25-30 years with the exception of the Control Plant (Electronic) assets which range between 5 to 10 years.
Strengthening
Increase in the capacity of an asset to cater for increased electrical load demand.
Reliability
The improvement in the performance of an asset to prevent degradation or failure of the asset. In the case of Distribution such projects would entail inclusion of redundancy in the design of the asset.
Direct Customer
Projects that are initiated and paid for directly by external customers. These include new points of supply, additional points of supply, and improvements to existing points of supply. 14

2019/10/08 41 Ankerlig Combined Cycle Gas Turbine (CCGT)
Phase 1A
Installation of the dual fuel burners – complete
Phase 1B
This is the balance of plant needed to enable the plant to burn natural gas. The project is currently in the definition phase, finalising some basic and detail designs. This scope includes the civil works, gas receiving station, distribution piping, control skids, electrical and control and instrumentation. The next activity on this project is to develop the works information and thereafter the gas supply agreement has been concluded.
Phase 2
The scope of work for conversion of the plant to Combined Cycle has been developed up to basic design stage. For this project to progress, Eskom needs a determination from the Department of Energy, a gas supply agreement to be in place that makes economic sense to Eskom, and all the required licenses and permits issued.
