Achieving self-sufficiency in electricity generation in Zimbabwe

Bulawayo Power Station
As Zimbabwe enters its third week of electricity blackouts under the national load shedding programme announced by the country's power utility, Zimbabwe Electricity Supply Authority (ZESA). The experience for various consumers seems like a déjàvu as rolling power cuts had been a daily norm from 2000 up until 2013 when prepaid meters were introduced. The power utility communicated that the power cuts are a result of demand and supply mismatch, low water levels at Kariba Power Station, generation constraints at Hwange Power Station and limited imports of electricity from traditional suppliers in the SADC region. Zimbabwe is currently generating less than 820MW from three power stations against a daily peak demand of 1600MW in winter and 1400MW in summer. Harare and Bulawayo power stations are not generating any electricity at the moment.

Zimbabwe imports at least 50MW daily from Eskom of South Africa and 100MW from Hidroelectrica de Cahora Bassa (HCB) of Mozambique to meet the supply gap, but can access up to 450MW from the two regional power utilities if it pays off its arrears which amount to $80 million. As a result of outstanding debts, the two suppliers have reduced exports to Zimbabwe by 50MW and 100MW respectively until their dues have been cleared. The situation has been made worse by low water levels in Kariba dam where Zimbabwe and Zambia share equally less than 1000MW currently being generated by Kariba Power Station.
Zimbabwe has 5 power stations which have a combined generating capacity of 2400MW. Years of mismanagement, poor planning, underinvestment and corruption in tenders to upgrade aging power stations or develop alternative renewable energy sources have taken the country back to a familiar problem. The country now pins its hopes on the ongoing 600MW Hwange Power Station expansion funded to the tune of $1.5 billion by China Exim Bank, being undertaken by Sinohydro from China. The project is expected to be complete by March 2022. The 2400MW Batoka Gorge Hydro Electric Scheme (Being developed jointly with Zambia) is still to commence and should be completed by 2025 if the $5 billion funding is secured on time. However there are a lot of initiatives that Zimbabwe can push to ensure self-sufficiency in electricity generation in the next 3 to 5 years. These include;    

Electricity tariff review
The overarching goal for the government is to ensure that the tariff charged for electricity consumption allows ZESA to break even and keep the cost of production in the economy at optimum levels. Currently ZESA charges $0, 0986 per kWh ($0.028 when using the Inter Bank rate) while it costs $0.11 per kWh to produce electricity locally. Eskom and HCB charge $0.13 per kWh, slightly below the regional average cost of $0.14 per kWh. This mismatch means that ZESA will continuously sink into debt in order to sustain electricity consumption locally. Added to that, consumers owe ZESA over $1.2 billion in unpaid bills and it owes suppliers its $500 million in turn. The first task is to streamline ZESA operations and complete restructuring of operational costs to ensure that the organization operates efficiently. After that ZESA should be allowed to charge just above $0.14 per kWh to domestic consumers (non-commercial consumers) and a subsidized rate 20% to 40% cheaper for agricultural, mining, commercial and industrial consumers depending on electricity usage in production.

The benefit for such a tariff would be to foster discipline in electricity usage for domestic consumers and pursuance of renewable energy solutions (Solar) for commercial, industrial or institutional consumers. More importantly a competitive tariff allows independent power producers to invest and supply the national grid at competitive rates. According to neZWire (2019), the sub-economic tariff is one of the major issues keeping energy investors away. Over the past 5 years, ZERA has licensed over 51 Independent Power Producers (IPPs), but those projects remain grounded due to low tariffs which make no business sense for financiers to fund local energy projects. Investors also demand a bankable Power Purchase Agreement (PPA), a long term offtake agreement with a creditworthy buyer of the electricity. ZESA is not seen as creditworthy enough to allow debt repayment or a predictable and sustainable revenue stream. This may in turn affect securing favorable credit lines for the funding of other upcoming schemes such as Gwanda, Insukamini and Munyati Solar projects, Batoka Gorge and Gairezi Hydro Electric projects.

Dealing with red tape in licensing
Once tariffs are reviewed upwards, the government may then structure tax holiday schemes in exchange for electricity supply to the national grid with independent power producers for Solar, Wind and Gas projects. To ensure this, there is need to shorten the license application processes for IPPs with Ministry of Energy and Power Development, Zimbabwe Energy Regulatory Authority (ZERA), Environmental Management Authority (EMA) and Zimbabwe Electricity and Distribution Company (ZETDC) all involved in licensing new players over and above the usual institutions and local authorities. Zimbabwe is endowed with abundant natural energy sources and local electricity production from clean energy sources is way cheaper than importing power from regional suppliers. If all the planned projects by private players are implemented in the next 3 to 5 years, Zimbabwe has potential to be self-sufficient in electricity generation and export excess capacity.

PPPs in repowering projects
ZESA is currently engaged in repowering projects for Munyati, Harare and Bulawayo Power stations. The entity recently cancelled the US$133 million tender for the repowering of Munyati Power Station awarded to an Indian company, Jaguar Overseas and local partner Intratek, after the firms failed to secure funding for the project four years after winning the bid. Efforts to get the same contractors to begin work at the $104 million Harare Power Station have stalled as the contractors want guarantees from Afreximbank that there is funding for the project, while so far only $52 million has been secured from the regional bank and requires agreements between the contractor and the power utility so as to be released.  After securing $110 million from India's Eximbank, Bulawayo Power Station repowering has been stalled by contractual dispute between ZESA and Bulawayo City Council (BCC). In order to resuscitate these projects, ZESA may need to re-tender and start afresh with an eye for Private Public Partnerships (PPPs) with potential funders. This allows potential funders locally and internationally to be partners in the management of the project to ensure efficiency in electricity generation. This route is largely depended on the tariff of the day for return on investment.

Full smart metering
In order to grow revenues and ensure sustainability, ZESA needs to smart meter all electricity consumers as a critical success factor. Smart metering allows the struggling entity to collect steady revenue inflows to pay for power imports in the mid-term while servicing credit lines used in repowering aging power stations. ZESA so far has less than 700 000 smart meters countrywide against a possible number in excess of 2.5 million. The entity has licensed close to 20 firms to help meet the smart meters demand by new customers however the ongoing foreign currency shortages have stalled the project. The smart metering project is a game changer for the power utility as it brings the power utility up to date with international best practices and allows them to supply electricity to prepaid consumers.
A review of the electricity tariff therefore provides a firm foundation for economic production of electricity on the local market. It will allow independent players to commence and complete planned projects while ensuring optimality for ZESA even when the country fails to receive good rains for powering Kariba Power Station.  Zimbabwe has massive electricity generation potential to ensure self-sufficiency and that potential needs private players to come on board for full realization. This may take the form of PPPs, Joint Ventures (JVs) or various other models with the power utility hence the need for complete the smart metering project to guarantee effective demand and payment of electricity.
