Increased electricity generation: Implications for end-user tariffs

The installed capacity of Uganda’s electricity generation increased to 1,177MW in March 2019, following the commissioning of the Isimba Hydro Power Plant (HPP) that added 183MW to the National Grid. The Isimba Hydro Power project was developed by the government with 85 per cent of the project costs financed with a loan from the EXIM Bank of China, and 15 per cent financed by the Government of Uganda.

The Isimba Hydropower Plant’s addition to the National Grid is timely for support of government policy on accelerated access to clean energy and industrialisation for the country’s socio-economic transformation.

However, some stakeholders have used different media platforms to cast doubt on the possible reduction in Electricity End-User Tariffs following the commissioning of the Isimba hydro power in March 2019, and the 600 MW Karuma HPP expected later in December 2019. In light of the several assertions and discussions about the expected Tariff trajectory due to these projects, the Electricity Regulatory Authority clarifies as follows:
The Isimba and Karuma Hydropower Plants have been developed by the government, with Government being the borrower of the project debt. Compared to privately-developed power plants, Isimba and Karuma will generate electricity at relatively lower Tariffs over the term of the Licence.

The Electricity Tariff for the two plants will reduce over time, in a phased manner, from US Cents 4.16/kWh (year 1 to year 15) to US Cents 1.01/kWh (after year 15) for Isimba Hydropower Plant. For the Karuma Hydropower Plant, the electricity tariff will reduce from US Cents 4.97/kWh (year 1 to year 10) to US Cents 2.7/kWh (year 11 to year 15), and US Cents 1.17/kWh (after year 15).

The changes in the generation Tariffs for the respective plants is on account of fluctuation in the debt service obligations. Basing on these generation tariffs and the utilisation of the power plants, the Weighted Average Generation Tariff is projected to reduce.
Following the commissioning of the Isimba and Karuma hydropower plants, a critical factor for the reduction of Electricity End-User Tariffs will be growth in demand for/consumption of electricity. The generation Tariff for Isimba Hydropower Plant is lower than the Weighted Average Generation Tariff.

Increase in electricity consumption (for both domestic and industrial customers) will lead to increase in dispatch/utilisation of Isimba Hydropower Plant. This will result into reduction in the Weighted Average Generation Tariff and, therefore, reduction in the End-User Electricity Tariffs. In support of the Demand Growth agenda, the government of Uganda working with several stakeholders has initiated several measures aimed at growing demand and increasing the consumption of electricity. These include:
l Heavy investment in industrial parks where industries are expected to consume a substantial amount of energy. Out of the 25 planned industrial parks, works on four electricity substations in Mukono, Iganga, Namanve, and Luzira are in advanced stages, with commissioning expected by June 2019. The 25 industrial parks are projected to consume up to 1,000MW in eight years’ time (by 2027).

-Electrification of all sub-counties across the country and all potential consumers on the sub-county electricity lines. This project is at mobilisation stage and once implemented, all sub-counties shall be connected to electricity.

-In August 2018, the government launched the Electricity Connections Policy to accelerate access to electricity across the country. The policy targets to promote mass electricity usage by all Ugandans with a connection target of 300,000 domestic customers per year.

-In order to support the Electricity Connections Policy, the government obtained funding to the tune of $200,000 from the World Bank, for the Energy for Rural Transformation (ERT) Programme (Phase III). Part of this funding will be utilised to improve electricity connection, targeting growing the number of Certified Wiremen/women and contractors. These will provide sufficient manpower to connect houses and factories in a timely manner.

- For industrial customers, the Electricity Regulatory Authority is implementing an incentive for accelerated connection through the Energy Rebate Mechanism. The rebate mechanism ensures that industrial customers who use their own resources to fund an electricity connection to a plant/industry recover their money over a period of three years through consumed energy rebates.

- The government is fast-tracking the implementation of regional interconnection projects, which will boost export of power within the East African region, with an export potential of 690MW. With these initiatives aimed at massive electricity consumption, the revenue base of the electricity supply industry will grow, subsequently leading to reduction in the End-User Tariffs.
