2.9 E LECTRICITY
2.9 E
LECTRICITY .Electricity is one of the four basic services to be provided to all residents of the CoT. The department of Services Infrastructure provides the community/residents, commercial and industrial sectors of Tshwane with Electricity, Services. The department has to ensure the services are of high quality and that interruptions are minimal or eliminated.
The Department is responsible for the long term infrastructure plan to support sustainable long term vision of the City. Its objective is to improve access to electricity services for the satisfaction of essential needs of consumers in Tshwane.
The main objectives of the related to electricity provision include the following:
To provide an adequate supply of bulk electricity on a continuous basis in an economic, effective and efficient manner, and at an acceptable quality and price to satisfy the needs of our clients
To distribute electricity in a sustainable, effective and efficient manner to the satisfaction of our clients, stakeholders and communities in accordance with their expressed needs
To improve access to electricity, services for the satisfaction of essential needs of consumers in Tshwane through effective and efficient planning; provisioning and implementation of new infrastructure
Provide public lighting services in the licensed areas within the City of Tshwane
In 2013/14 financial year the City electrified the following areas: Ga-Rankuwa ext. 24, Sokhulumi, Steve Biko, Rethuseng (Mabopane), Mamelodi phase 1; 2; 3; 4; ext. 11 and 18; Phomolong, Itireleng, Brazzaville and Soshanguve ext. 6, benefitting regions 1, 2, 3, 6 and 7.
ELECTRICITY FOR ALL BACKLOG ERADICATION
The Service Infrastructure department provides electricity services to all communities in Tshwane, both formal and informal settlements. To fast-track this process the department prioritises areas where there is no access to electricity with specific focus on low cost housing. The budget amount of R65million in 2013/14 was channeled to the Electricity-for-All (710178) project in support of the National Electrification Programme and the `Universal Access’ target. The Electricity for All project ensures that newly formalised and informal settlements are electrified to address the electrification backlog and provide a basic electricity service to the Tshwane community.
Currently the electrification backlog at City of Tshwane is estimated at 145 047, this number mostly include areas which are still informal settlements. The department electrified a total of 22 987 houses in both Tshwane and Eskom supplied areas against a target of 9000.

PUBLIC LIGHTING
Security and visibility at night is a priority for safety of communities in South Africa. The City continues to receive petitions requesting lighting infrastructure in both formal and informal settlements.
The City accelerated the public lighting infrastructure programme and installed a total of 2 248 streetlights and 54 high masts in all regions in 2013/14 financial year. Streetlights are planned and installed on all major bus routes in townships to increase safety for pedestrians and motorists, whereas high masts are mostly installed in large open spaces to light hot spots which ultimately reduce crime levels.
BULK CAPACITY
The city provides bulk capacity predominantly on the basis of a 20 year master plan, which takes into consideration growth and new developments.. Amongst the major projects undertaken in 2013/14, were the construction of Wolmer Gomsand and Orchards substations with expected capacity of 40 MVA and 120 MVA respectively. These projects are expected to augment the electricity supply and support the initiatives of the municipality to provide reliable services and attract prospective investors.

NEW CONNECTIONS
The “New Connections” programme provides electrical supply up to 11kV within the Tshwane Area of Supply to all consumers. This involves the management, planning and processing of all electrical supplies, and to speedily and accurately compile a quote in accordance with the applicable Tariff Document, Conditions of Supply, By-laws and necessary safety standards. The entire project is application driven based on the needs of our consumers. This includes single and three phase connections which could be new or upgrade of existing supplies for residential, businesses, commercial industrial and street reserve connections. The project had an allocated budget of R 23 million.
In 2013/14 financial year, 4063 new connections were made in formalised areas. Areas that benefited are Temba, Itsoseng, Kgabalatsane, Ga-Rankuwa, Mamelodi and Mabopane.
PREPAID METERS
On the 1st October 2013, the City of Tshwane began the rollout of the smart prepaid electricity meter programme. This programme was aimed at installing new smart pre-paid meters and replacing old electricity meters through its Security of Revenue project which will allow automated meter reading, data management, data processing and analysis.
The project is aimed at increasing electricity revenue as the customers have to pay upfront for the use of electricity.

REDUCTION IN UN-ACCOUNTED FOR ELECTRICITY
The annual electricity distribution losses comprised of technical and non-technical losses, which is defined as the difference between electricity purchased and electricity sold. The average distribution losses for the 2013/14 financial year are 11.91%.
Technical losses are results of electricity losses while being distributed from the source of generation through transmission and distribution network to the final consumer. The wires (copper or aluminium) being used to distribute electricity has certain resistance which resist the throughput of current, as a results there is certain portion of electricity that is lost due to distribution and it is termed technical losses NERSA acceptable figure for network like Tshwane is estimated to be 7%.
Non-technical losses are amongst others the result of administrative and technical errors, negligence, theft of electricity, tempering with meters and connections which form part of illegal consumption.
The CoT five year targets to reduce the non-technical losses activities like theft, illegal connection to less than 2%. The refurbishment of the electricity network will assist in managing the technical losses
65 | P a g e
because the technical losses increase with the aging of the electricity network. The five year target is to have unaccounted losses to 8% (7% technical and 2% non-technical).
Further, the demand for energy has been declining and such the sales have been low.
The department is currently busy with the following initiatives to reduce the non-technical losses:
Weekly cable operations to remove illegal connections
Daily meter audits
Normalisation of prepaid meters that are not buying electricity
Strengthening of network and refreshment
Installation of temper boxes
Electrification
The department is also busy addressing the technical losses by:
Refurbishing and replacing old equipment in the network
Strengthening over headlines
