After the successful commissioning of units #2, #1, and #3 in 2016, 2017, and 2019 respectively, the installation of unit #4 was completed beginning of 2020 as per schedule. However, the finalization of the commissioning of this unit was suddenly halted in mid-March 2020 due to the COVID-19 pandemic. Unit #4 was the last part of the retrofit project to be commissioned but travel restrictions prevented the ANDRITZ commissioning team from travelling to Ghana.

Nonetheless, the pressing need for electrical energy led all involved parties to seek out a solution. As a result, a special charter flight was organized to fly in the team and finalize commissioning of the last unit. Following a huge effort by the customer, the local authorities, the responsible ANDRITZ team, and Goldeck airline, in August, two supervisors and five commissioning engineers departed from Vienna. After picking up the commissioning coordinator in Beograd, Serbia, and after a fuel stop in Tamanrasset, Algeria, the chartered plane safely arrived at Accra. After a 10-day quarantine in a government-determined hotel, followed by a four-day stay in the isolated ANDRITZ camp, the outstanding works could be started. Commissioning, including performance tests, were successfully completed on September 19, 2020.

The Kpong generating station is a run-of-river hydropower station and was originally commissioned in 1982. After 30 years of reliable operation, the power generation components experienced failures and forced outages. A retrofit project was initiated to update the equipment of the plant to modern standards and to ensure the reliable operation for the next decades to come.

In 2013, ANDRITZ received a contract from Volta River Authority, a 100 % state-owned public entity in Ghana, for the modernization of the entire hydropower station. The contract covered design, manufacturing, supply, installation and testing as well as the commissioning for the mechanical and electrical equipment. This included intake roller gates, turbines and governors, generators, and DIATECH equipment, excitation -, protection -, control - and protection systems, as well as powerhouse station service facilities.

Now, all four units of the Kpong hydropower plant are again fully operational to the utmost satisfaction of the customer. The power plant plays an essential role in the mitigation of the climate change as it is saving about 400,000 tons of carbon emissions every year, thus supporting the country on the way to a sustainable future. The safe and reliable annual production of about 1,000 GWh of electrical energy to the national grid is an important cornerstone of Ghana’s climate policy.
