Museveni Directs Scientists On Natural Gas

hospital geneva;”>Museveni made the revelation on Sunday while meeting a consortium of South African energy at his country home in Rwakitura, Kiruhuura District.

“We have about 5 big energy sites on the Nile; Karuma, Ayago, Oryang, Kiba, Murchison falls, Kalagala and Isimba. Our target is 42000 MW in the next 18 years. There is going to be gas opportunities with oil. I have directed our scientists to investigate the usage of associated gas for power generation,” the President told his guests.

The group, accompanied by a representative of the South African High Commissioner to Uganda, was led by Mr. Richard Vries, the Executive Officer of Gibb Holdings.

The group includes a strong pedigree of companies that cover end to end engineering projects in dam construction and a representative of Development Bank of South Africa (DBSA).

Some of their projects include building the biggest dam on the continent on Ngula River in South Africa that will generate 1300 MW, Kabombo Gorge in Zambia, Losuthu Scheme expected to generate 1000 MW, the largest Wind power project on the continent in Kenya, Singida Wind project in Tanzania and operate a 600 MW Kelvin power plant in South Africa.


Mr. Vries informed the President that with Uganda Government’s planned contribution to construction finance, the group will achieve the President’s target of a lower tariff of 6cts per Kwh.

President Museveni created an energy fund a few years ago for which Uganda has been saving that will come in handy in construction of dams in the country.

“I thank you so much and I welcome you. African people have been asleep talking about development without electricity. Energy is key to economic growth. All countries in Africa have got very low power except a few like South Africa and Libya,” said Museveni.

“We are determined to see that within Africa there are groups which have the money and engineering capacities. We are happy to have such potential in Africa,” President Museveni told the group.


Research shows that a gas power station turns the chemical energy in natural gas into electrical energy that can be used in homes and businesses.

Natural gas is pumped into the gas turbine, where it is mixed with air and burned, converting its chemical energy into heat energy. As well as heat, burning natural gas produces a mixture of gases called the combustion gas. The heat makes the combustion gas expand. In the enclosed gas turbine, this causes a build-up of pressure.

The pressure drives the combustion gas over the blades of the gas turbine, causing it to spin, converting some of the heat energy into mechanical energy. A shaft connects the gas turbine to the gas turbine generator, so when the turbine spins, the generator does too. The generator uses an electromagnetic field to convert this mechanical energy into electrical energy.

After passing through the gas turbine, the still-hot combustion gas is piped to the heat recovery steam generator. Here it is used to heat pipes full of water, turning the water to steam, before escaping through the exhaust stack. Natural gas burns very cleanly, but the stack is still built tall so that the exhaust gas plume can disperse before it touches the ground. This ensures that it does not affect the quality of the air around the station.

The hot steam expands in the pipes, so when it emerges it is under high pressure. These high-pressure steam jets spin the steam turbine, just like the combustion gas spins the gas turbine. The steam turbine is connected by a shaft to the steam turbine generator, which converts the turbine’s mechanical energy into electrical energy.

After passing through the turbine, the steam comes into contact with pipes full of cold water. In coastal stations this water is pumped straight from the sea. The cold pipes cool the steam so that it condenses back into water. It is then piped back to the heat recovery steam generator to be reused.

Finally, a transformer converts the electrical energy from the generator to a high voltage. The national grid uses high voltages to transmit electricity efficiently through the power lines to the homes and businesses that need it. Here, other transformers reduce the voltage back down to a usable level.
