Re: Tanesco yajitoa ununuzi Dowans; yaipiga mkwara nchi

There is enough water at the Tanzania Electric Supply Company (Tanesco) plant at the strategic Mtera Dam to generate power for many months to come, The Guardian has established. This is contrary to suggestions that the intermittent power cuts which have hit different parts of the country for the last several months were linked to fast-falling water levels at the dam.
Power generation at the two main units of the dam, which lies at the border separating Dodoma and Iringa regions, was in full swing when a reporting crew from this paper made a surprise visit to the area mid-this week.
Tanesco officials and workers at the 100-meter underground Mtera plant said water levels have stood at decent levels for the last two years and talked of stable national grid power supply unless unforeseen circumstances intervene.
The last readings taken on Tuesday showed that the water level had reached 696.07m above sea level, way above the 690m recommended as the level below which power generation is suspended.
Mtera power station acting manager Stephen Mfumbutsa said in an interview that there was gradual but steady increase in the dam`s water level since last month.
``There have been enough rains in and around catchment areas in Mbeya and Singida regions as well as other places that feed Ruaha and Kitego rivers, draining into Mtera Dam. This is good news to us because it means that power generation is assured,`` he noted.
``Water is extremely precious for us. In fact it is much like an oil reserve that no one would like to see depleted,`` he added.
The official, who gave the explanation while running through a diagram with details on the national power grid, said Mtera has two 40-MW generating units and both have been running smoothly throughout for months now.
"Power consumers have nothing to worry about because, as the trend shows, there is currently no possibility of power rationing," a confident-looking Mfumbutsa stated.
Commenting on the causes for the recent intermittent power fluctuations in some other areas in the country, he said the situation was unfortunate but was not due to problems with their production units.
Elaborating, he said it was likely that one reason was faults originating from the power transmission lines.
Gosbert Matandu, a long-serving Mtera station technician now also serving as assistant to the operations manager at the site, then took the journalists to the dam site for a verification of the day`s water level readings.
Pointing at the yardstick (graduated iron bar), Matandu said once the water level exceeded 698.5m, the maximum level for the dam`s holding capacity, operators would be obliged to open the floodgates to avoid serious consequences.
``This is the level of water for today. The readings are closely monitored day and night to make sure that the amount of water meant to have the runners (two turbines) going was within the recommended level,``he explained.
The aim is to avoid air-sucking in case of low water level which may cause cavitations to the runners, he said.
Meanwhile, Mtera station operations manager Joseph Chomola produced a computer-monitored chat which showed monthly water level readings.
That was in an attempt to ``clear the air`` and assure consumers that power would continue to flow at both Mtera (80MW) and Kidatu station (204MW), both of which receive water from Mtera Dam.
Chomola said daily records showed that there has been a gradual increase in the level of water since the beginning of this month.
``For example, on February 1 it was 696.03 m and the readings on February 10 (the day The Guardian toured the station) was 696.07m. It is our hope that the pleasant situation will continue because the long annual rains are expected to set in shortly,`` he pointed out.
He added: ``Even if the water level were to fall by a whole two centimetres a day, God forbid, it would have taken more that 300 days to reach the minimum level of 690m``.
Plant Operator (Control Room) Alfred Machismo sat at a corner on Mtera station's lowest floor, surrounded by several direct telephone lines and computer sets "to make sure that any unusual alarm sounded is promptly attended to".
``As you can see, everything is running at full capacity here. We have deliberately lowered the output to 30MW and 28MW for in line with instructions from the Grid Control Centre in Dar es Salaam, popularly known as SCADA, depending on the load or consumption rate at the specific moment,`` he explained, adding: ``Things are perfect and there is no cause for consumer alarm or panic.``
A beaming Machimo then fixed his eyes on the huge control unit, as live meter readers monitored every section of the production process.
Tanesco said recently that the nation is on the verge of a power crisis and announced an ambitious plan to put up a new 400KV national grid to support its existing dilapidated power supply backbone.
The giant state-run power company blamed frequent blackouts experienced in Dar es Salaam and several other regions recently to an ``overwhelmed`` Tanesco network.
According to Tanesco, the new transition backbone is to be built from Iringa to Shinyanga through Singida Region and is to meet increased countrywide demand for electricity.
The firm`s capacity to generate and supply power has been seriously eroded over the years chiefly by a high rise in demand, sabotage of its infrastructure and transformer oil thefts.
Ensuring quality and reliable supply becomes an increasingly nagging problem as demand continues rising, officials and analysts say.
The existing 220KV and 132KV transmission system suffers from frequent voltage depressions, surges and sometimes total outages, according to Tanesco Managing Director Idris Rashidi.
