TANESCO’s Generation division is responsible for all
power generation functions owned by TANESCO. Other sources of generation
are from independent power producers (IPPs) which feed the National
grid and isolated areas as well.
TANESCO’s generation system consists mainly of Hydro
and Thermal based generation. Hydro contributes 57 % of total power
generation from january 2012 up to december 2012.Gas and Thermal
contributed the remaining amount. During the year 2012(Jan to Dec 2012)
the total units generated to the grid and isolated plants was
5,759,756,313 kWh or units.TANESCO own generation was 3,110,436,062 kWh
while the imports from IPPs and neighbour countries (Uganda and Zambia)
were 2,649,320,551 kWh.
In recent years TANESCO has impleted a thermal hydro
power generation mix programme. A substantial amount of generation comes
from gas and diesel thermal generation through own plants and
independent Power Plants (IPPs). Own thermal generation comes from the
Dar es Salaam-based Ubungo gas based 100MW plant,Tegeta 45MW which was
commissioned in December 2009 and Ubungo || Gas Plant which was
commissioned in July 1st,2012 by Hon.Prof Sospeter Muhongo (MP),Minister
for Energy and Minerals.
Future generation plan will largely be dominated by Coal and Gas power plants.
TRANSMISSION
TRANSMISSION
TANESCO owns interconnection power grid made up of
generation system transmission and distribution system. Transmission
system comprises of forty three (43) grid substations interconnected by
transmission lines. The transmission lines comprise of 2732.36 km of
system voltages 220kV,1538.5km of 132kV;and 546 km of 66kV, totalling
4816.86km by the end of November, 2012
Transmission lines use pylons made of still. Almost
all the transmission lines are radial single circuit lines. The system
is all alternating current (AC) and the system frequency is 50 Hz.
The total installed capacity in the Main Grid System
amount to 1438.24MW. The system is hydro-thermal mix, constituting hydro
561.84 MW (39%) from thermal plants (gas - 501 MW and liquid fuel
375.4MW) mainly from IPPs.
The Main grid system demand of 2011 was 828.99 MW as
recorded on November 09th 2011 at 20hrs. The highest grid system demand
of 2012 was 851.35 MW recorded on 22.10.2012 at 20hrs. The transmission
system losses recoreded in 2011 was 6.3% and 6.12% as a record of the
year 2012.
Distribution and Customer Services
The marketing Business Unit stands at
the customer end of the electricity supply chain and is therefore
Tanesco’s major interface with customers. It deals with distribution of
electricity, promotion of services and all customer service matters.
The unit is headed by a General Manager
who is assisted by two senior managers; a senior manager for marketing
and customer service on the one hand and a senior manager for
distribution on the other. Services of the Marketing Business Unit are
delivered to customers through a network of 24 Tanesco defined regions.
To ensure effective management of operations, these regions are
clustered into five zones each headed by a Zonal Manager.
MARKETING AND CUSTOMER SERVICE DIVISION
The Marketing and Customer Service
Division is led by the Senior Manager Marketing who oversees the
operations of three sections namely the Marketing Section, the Call
Centre Section and the Large Power Users section.
The Marketing Section
The marketing section at Tanesco is
entrusted with the responsibility to develop insight into customer needs
and deliver promotion campaigns that will elicit customer interest and
favourable action towards Tanesco services. Click here for further information on the functions of this section.
Large Power Users Section
It is estimated that over 80% of all Tanesco revenue is earned from
only 1,700 Large Power Users (LPUs) who forms 0.24% of all customers
countrywide. LPUs are those customers that consume over 7,500kWh per
month. Ironically, the biggest non technical losses also originate from
this group of customers which is only 0.24% of total customers.
Management of LPUs is therefore of paramount importance to Tanesco.Safeguarding the 80% of revenues from the LPUs is given high priority. That is why meter commissioning and meter auditing to LPUs is administered right from the Head Office’s Marketing Division via the Department of Large Power Users. The LPU Department runs two sections:
In 2009 the AMR meters were approved to be rolled out to all LPU customers. By the end of year 2009, 2,130 AMR meters were procured for LPUs and 8,000 AMR meters were procured for Medium Power Users (Tariff 1 customers using three phase meters). Accordingly, a third Section is under establishment within the LPU Department that will manage the AMR System. It is known as ‘The AMR Center’. This Section is expected to take off by February 2010. These meters are not only powerful weapons in the war against energy theft, but also they will cut down meter reading costs, they will eliminate meter reading errors, and for the case of Tariff 1 three-phase customers, they can be disconnected remotely for non-payment of bills, further cutting down operation costs.
Call Centre Section
This section is currently in the
establishment stage. It will be run by a manager assisted by a principal
customer service officer. Their main task at present is to establish a
state of the art call centre that will enable handling of customer
service issues from across the country.
The centre will be based at Tanesco Head
Office, Umeme Park, Ubungo Dar es Salaam from where customer querries,
requests for assistance and complaints will be received and handled. In
essence the call centre will act as a coordinator for resolving customer
service issues.
DISTRIBUTION DIVISION
Headed by the Senior Manager
Distribution, this division is responsible for distribution, Health
& Safety as well as rural electrification.
Operations Section
It is through this section that the
Marketing Business Unit overseas the operations of regional operations.
The section monitors regional operations through regular reports such as
weekly and monthly reports and also various statistical analyses based
on regional reports.
One of the major roles of the operations
function is to ensure the availability of distribution materials of the
right quality to enable smooth distribution of electricity to
customers. The section also carries out survey for the purpose of
mapping out distribution networks. To ensure continued and uninterrupted
distribution services, the operations section has also been entrusted
with the responsibility for overseeing maintenance of electricity
distribution network.
The Distribution function also draws
specifications of various distribution materials to as to ensure
materials procured conform to the required standards.
The Operations Section of the
Distribution Division also carters as an R&D unit thus working in
search for new technology that will ensure efficient use of materials at
low cost.
Health & Safety Section
While we all need electricity, we all
should know that electricity is dangerous. Tanesco workers are exposed
to risks of accidents while at work. Our customers are also exposed to
electricity related risks due to poor electrical installations and
faulty electrical appliances. Electricity can kill or cause severe and
permanent injury but careful planning and straightforward precautions
can help us avoid most of the accidents.
Our health and safety unit was
established for the purpose of ensuring all possible measures are taken
to prevent electrical accidents and creating a health wise sound working
environment in accordance with the Occupational Health & Safety
Act. To learn more about this section click here.
Electrification Section
Tanzania has one of the lowest
electrification levels on this planet. Our electrification section has
been tasked with the challenge of identifying new areas for
electrification and developing proposals for the purpose of soliciting
funds.
Also the section acts as a link between
the company and the Rural Electrification Authority as well as other
financiers of the various rural electrification projects such as the
ADB, the World Bank, and NORAD.
The Electrification Section also ensures
the proper management of the various projects that are under
construction up to the time they are handled to the respective regions.
