Customer Services
• Total electricity sales of 216 561GWh and 5 million customers (including transmission customers) as at 31 March 2013
• Supplies approximately 95% of South Africa’s electricity supply• Two main types of customers:
• Redistributors: Mainly municipalities that sell electricity to end customers.• Direct customers: Industrial, commercial, mining, agricultural and residential consumers
• Key Sales and Customer Service unit deals with customers using ≥100GWh of energy per year• As at 31 March 2013, Eskom had 5.0 million customers accounting for electricity revenues of R126.7
billion• One customer has a supply contract indexed to commodity prices• A member of Southern African Power Pool (“SAPP”)

Distribution: Division Profile
To service the customer through provision of reliable electricity by building, operating and maintaining distribution assets, while also acting in the national interest by actively partnering with the wider industry in resolving distribution industry issues and enhancing stakeholder relations
Scope and mandate
67 488km of distribution lines269 535km of reticulation power lines6 960km of underground cables3 580MVA of new transformer capacity15 350 employees
Asset base Organisation structure
• Implemented several safety initiatives, which saw an improvement in most of the safety indicators• Sustained improvement of the system average interruption duration index (SAIDI) and the system average interruption frequency index (SAIFI)• Electrification connections exceeded target and also created 4 320 job opportunities• Since inception of the electrification programme in 1991, a total of more than 4.3 million (2012: 4.2 million) homes have been electrified
Highlights and output
• Employee and, in particular, contractor safetyperformance and lost-time injuries• High levels of theft of equipment andelectricity, including illegal connections, affectnetwork and service performance, increasingEskom’s costs• Ageing networks, making maintenance achallenge
Key challenges and priorities
• 5.0 million customers nationally• Nine provincial operating unit Structures are now in place,with fully functional management.

Distribution Network Planning Process
6
• Electrification Plan • Land use study • Demographic study • Econometric study • Zoning exercise • Load forecast - geo-based - trend-based • Demand & energy forecast • Scenario creation
Gather & Verify Network & Load
Information
• Geographical background data • Network asset information • Load (MD) profiles • Reports, Guides, Standards, etc • Customer data • Electrification data • Performance KPIs • Transmission plans • Refurbishment plans • Environmental issues
Identify &
Evaluate Alternatives
Capital Plan
& Financial Evaluation
Reporting, Approval
& Project Initiation
• Formulate alternatives • Map alternatives • Technical evaluation - load flow - fault studies • Reliability analysis • Life cycle costing • Economic evaluation • Integrated plans - transmission - sub-transmission - reticulation
• Select Preferred Alternatives • Capital Requirement Plan - Phasing • Financial Evaluation - cash flow - income - tariffs
• Reporting - conceptual plan - geographical presentation • Approval - NMP / NDP • Project initiation - DPA’s / CRA’s • Environmental assessments - SEA’s (EIA’s) • Long lead-time equipment • Servitude acquisition
Analyse Existing
Network Capability
& Define Problem
Statement
• Build network models • Analyse existing network capability - present loads - future loads • Analyse plans - refurbishment - electrification - environmental • Analyse reliability requirements • Define problem statement
Study Objective
& Review of Study Area
•Define study objective •Compile map showing existing NMP/NDP boundaries • Map showing existing networks • Prepare network SLD’s • Review/redefine Study Area boundaries

Study
Integration of Electrification, Refurbishment, Transmission and Environmental Plans
• Comprehensive Network Planning process - Supported by appropriate Network Planning criteria/standards
• Network Development Plans reviewed every three years (license condition)

Electrification Highlights Since Inception
• Added ~4.3 million households to the grid since 1990
• Electricity access has significantly increased from 1994 to-date:
– Nationally from 36% to 83%– Rural electrification from 12% to 57%
• Government’s target of 1.75 million connections between 1994 and 2000 exceeded through a self-funded and managed programme
• Massive delivery– A connection every 30 seconds– A pole every 10 seconds– 200 metres of cable every minute
• Eskom and Shell Joint Venture connected around 6,000 solar home systems between mid-1990s and mid-2000s
• Nearly 32,000 systems have been installed by Non Grid Service Providers granted concessions by the DoE in 2003
There have also been a limited number of off-grid connections
Eskom has made significant strides in connecting South Africans to the grid +

Sub-letting refers to units constructed on a property in addition to the main home or primary dwelling and are not on an individual plot or stand in the title scheme/cadastre, and can be located within, attached to, or separate from, the principal dwelling.

Challenges To Achieving Universal Access
23-04-21 16
Increase of the cost per connection due to long Medium Voltage line (11 and 22KV )
Project management & design skills shortage;
Sparsely populated rural areas;
Infrastructure projects in support of other implementing agents;
Municipal upgrades for After Diversity Maximum Demand (ADMD)
Constrain due to reduced Eskom Capex expenditure;
• Refurbishment (Eskom funded)
• Network Upgrade (Eskom funded)
• Strengthening projects (Eskom funded)
• New build (Funded by DoE 70/30 principle applies)
23-04-21 17
Grid & non-grid, Master Plan (DoE & Eskom working on a Master Plan);
Agreed service levels of the non grid to be similar to grid;
Harmonization of government initiatives e.g. electrification and housing programmes
Aligned policies to facilitate implementation process (e.g. un-proclaimed, land usages);
Installation of two meters in double stand dwellers;
Increase fund allocation to cater for infrastructure projects:
Refurbishment of constraint networks related to electrification.
Upgrading of the networks.
70/30 principle in new builds networks to be continued.
Some Opportunities To Facilitate UAP Achievement
