Eskom fires supplier over inferior coal

Published

on

Eskom has terminated its contract with a major coal supplier at its Tutuka power station for consistently delivering poor-quality coal.
The power utility discovered that Just Coal CC was consistently delivering inferior coal, following a strict monitoring process of all its suppliers. After numerous site visits to the contracted collieries, it was determined that coal supplied to the Tutuka Power Station by Just Coal CC was not extracted from the contracted collieries.
“This is in breach of its contractual obligations to Eskom. The result is that Eskom is burning an unknown combustion characteristic coal resource at its Tutuka Power Station, potentially resulting in load losses,” said Matshela Koko, interim group chief executive, Eskom.

He added that in an effort to resolve the issue, Eskom requested technical information such as mine layouts and in situ coal qualities from Just Coal CC. “The information provided did not adequately address Eskom’s concerns.”

“On 16 March 2017, we had placed Just Coal in breach of its contractual obligations and requested additional technical information. We then afforded them until 23 March 2017 to provide the technical information and remedy the breach and they failed to do so.

“Eskom is intolerant of any deviations from the prescribed standards and processes. This, quite plainly, amounts to corruptions, which we cannot condone in any part our business. As a state entity, there is an innate expectation to be prudent and corruption-free in how we conduct our business,” he said.

The coal-fired, six boiler/turbine unit Tutuka power station is situated in Mpumalanga, and contributes 3,600MW supplied to consumers and industries throughout the country.

Cameroon: Three power plants financed by the African Development Bank to reduce power cuts

Published

For many years, Cameroon’s national electricity supply has been notoriously unreliable and subject to power cuts. The last significant electric system outage, which lasted eight hours, occurred last March and affected several of the country’s regions (the Far North, North, Littoral, Adamaoua, South and Centre regions).

However, three projects financed by the African Development Bank for $121.4 million in 2010-2011 are at last starting to provide long-suffering Cameroonians with much more reliable electricity.

Completion of work on transport lines, line maintenance and especially the replacement of wooden electricity transport poles with concrete poles are all part of the system improvements, whose goal is to increase the quality and reliability of public access to electricity.

The Lom Panga storage reservoir project is complete, but the dam’s generating plant is still under construction. In the meantime, two other power plants, Kribi and Dibamba, have begun working  to strengthen Cameroon’s generating capacity.

In November 2011, the African Development Bank awarded $62.9 million for the construction of Lom-Pangar, the hydroelectric generation’s ‘lungs’ in the country’s East region. The project included the construction of a reservoir (6 billion cubic meters of water retained) for regulating the Sanaga’s flow and optimising generation during low water periods at the Song Loulou plant (335 MW) and the Edea plant (224 MW). The production from these two plants has grown from 450 MW in 2011 to 729 MW now.

A 30 MW hydroelectric generating plant is under construction at the base of the dam. It will be linked to the Bertoua thermal plant by a 105 km 90kV line that should start to work in May 2021 following the installation of an evacuation station and the construction of its four turbines. Lom-Pangar will provide electricity to 150 locations in the region and will significantly reduce power cuts in the area.

“The Lom-Pangar dam will help save water in other reservoirs,” said Theodore Nsangou, the General Director of the Electricity Development Corporation (EDC), in an interview with a government publication in March 2018.

The 216 MW capacity Kribi gas-fired generating plant began to work in 2013 after receiving $32.8 million from the African Development Bank in July 2011 for an expansion project. Its production goal is 330 MW. Currently, the power plant has a 100 km 225 kV transport line connecting it with the Magombe substation in the Edea region in the country’s South region. The plant operates with natural gas (with light fuel oil as emergency backup) from the Sagana South offshore gas field.

During the dry season, the Kribi plant and its nine simple cycle gas turbines are truly the system’s “oxygen”, maintaining the country’s energy flow, particularly to the South’s interconnected system, which receives its electricity from Kribi.

The Kribi gas-fired generating plant and the Dibamba generating plant provide access to electricity for close to half of Cameroon’s population.

The Dibamba heavy fuel oil generating plant was also designed to meet the serious problem of power cuts during the dry season. It was the first of the three plants to receive financial support from the African Development Bank of $25.6 million in April 2010. Built to mitigate the country’s shortage of electricity, high demand quickly outpaced its capacity the day after it began operations.

Located in the outskirts of Douala, Cameroon’s second largest city, Dibamba is an 86 MW thermal generating plant with a 2 km 90 kV transport line linked to the network serving the most remote and densely populated areas in the country’s West region.

With an estimated 23,000 MW hydroelectric production capacity, Cameroon has the second largest hydroelectric potential in Africa and the 18th largest worldwide. The country plans to complete the development of its hydroelectric industries by 2035. Construction of the Nachtigal hydroelectric generating plan began in 2019 and will be complete in about five years, with an estimated generating capacity of 420 MW.

The African Development Bank has awarded a funding package of $154.8 million for the completion of this generating plant. Other development partners, such as the World Bank, the European Investment Bank and Proparco, are also involved.

UNDP, Sahara Group Target Energy Access To 10 Million Households In Africa

Published

on

New York, USA: September 24, 2019- The United Nations Development Programme (UNDP) and the Sahara Group have unveiled the Africa Renewable Energy Forum to boost access to sustainable energy for 10 million households in Africa through alternative energy initiatives and interventions.

Launched at the margins of the 74th UN General Assembly in New York, the Africa Renewable Energy Forum is expected to bolster ongoing partnership between UNDP and the Sahara Group that aims to create access to clean and affordable energy in Africa.

The forum will serve as a platform for policy discussions, multi-stakeholder collaboration and funding towards implementation of tailored renewable energy solutions across the continent. Ultimately, the platform will galvanise the political momentum needed to record significant progress through strong partnerships, effective regulation and mutual accountability.

The event had senior officials from both organisations in attendance including, Ahunna Eziakonwa, Regional Director and Assistant Secretary General for UNDP Regional Bureau for Africa, as Kola Adesina, Group Managing Director, Sahara Power Group, Pearl Uzokwe, Director, Governance and Sustaianability, Sahara Group, Bethel Obioma, Head Corporate Communications, Sahara Group and Babatomiwa Adesida, Private Sector Engagement Specialist, Sahara Foundation.

Africa has the highest percentage of untapped hydropower potential in the world, with only 11% utilization capacity. Whilst the global electrification rate reached 89% in 2018 and 153m people gained access to electricity (WB Stats, May 2019), the biggest challenge remains in the most remote areas globally and sub-Saharan Africa in particular, where an estimated 573m people are not connected to grid power.

With over 600 million Africans having no access to electricity, Ahunna Eziakonwa said the continent urgently needs to embrace renewable energy sources to sustainably connect the poorest and hardest to reach households. “Access to energy will enhance the cause of poverty alleviation and also yield huge benefits for education, healthcare, production, and socio-economic development. The UNDP-Sahara partnership is extremely crucial as it will provide a model for engaging a wide range of stakeholders to address the continent’s energy challenge in line with the SDG framework,” Ahunna stated.

Kola Adesina said the initiative has the potential to create over one million jobs in Africa as the continent continues its march towards achieving the 2030 SDG Agenda. “Renewable energy is still in its infancy as far as Africa is concerned. We need unrelenting awareness initiatives to inspire a mindset shift to renewable energy in Africa with the various governments, private sector and development agencies leading the charge. At Sahara Group we believe that interventions like the UNDP-Sahara partnership will enhance productivity and shared prosperity in Africa.”
