Investment Allocation Decisions in Transmission

Transmission Capital Plan for the

TPD period (2015-2024)

Categories FY15-24 (Rm)

Capacity Expansion 145,968

Refurbishment 7,680

Capital spares 2,397

EIA and servitudes 5,150

Strategic 1,066

Production Equipment 519

Total 162,779

Cost-Drivers in Grid Expansion • Load Growth:

o Connection of new and anticipated customer loads

o Resolution of Quality of Supply excursions

• Legal and Regulatory Compliance: o N-1 Reliability Investments

• Power Corridors

• Transformation Capacity

o Mitigation of Fault-level Exceedances (existing and anticipated)

• Integration of New Generation: o Eskom generation new build

o New and anticipated IPP generation

• Land Development: o Securing of Lands Rights and Environmental Authorisations

Summary: DoE REBIDS 1, 2 & 3

Eskom Investment to Enable

REBID 1, 2, & 3 (RM)

Constraints to Grid Access • Servitude Acquisition and EIAs (can take up 24 Months to resolve)

o IPP developments tend to be in close proximity of Eskom substations. This sometimes restricts access to other RE IPP participants due to limited powerline corridors through IPP properties

• Long Lead Times for New Infrastructure (can take up to 7 years):

o Post REBIDs 1, 2, & 3; there is very limited spare capacity on the existing Distribution and Transmission networks. Hence, necessity for deep strengthening.

• High Cost of the Shared Infrastructure (due to requirement for deep strengthening)

o Due to uncertainty of allocation of Preferred IPP Bidders, quotations are issued on an individual basis i.e. no other application is considered in the quotation. This potentially raises the cost of connection per quotation

• CELs issued to IPPs are non-binding but are utilised in the BID price, which is a binding, to the DOE IPP

Required Investment to Unlock

Capacity for Future IPP projects

Strategies to Optimise Infrastructure Requirements for Future IPP Projects

• Develop Renewable Energy Zones”

• Encourage the installation of smaller blocks of PV (e.g. < 50MW) closer to Load Centres

• Avoid Large Projects in Grid-remote areas

• Encourage Projects in Areas with Grid Capacity (Align Projects to GCCA doc)

Strategic Projects to Unlock REDZ

Wayforward

• Eliminate misalignment in the planning of the IPP programmes

(i.e. continue working with key stakeholders).”

• Special measures and resources

(to accelerate the Transmission infrastructure required for the IPP

programmes; e.g. strategic EIA’s; special funding mechanisms, etc.)
