Earlier this 12 months, the Economic Neighborhood of West African States (ECOWAS) offered its updated Grasp Plan for Regional Electric power Era and Transmission Infrastructure 2019–2033 (the Grasp Approach). The Learn Approach is part of ECOWAS’s drive to produce the West Africa Electric power Pool (WAPP) – a cooperative electrical power pooling system for integrating nationwide electric power method operations into a unified electrical power marketplace in the West African location. Like in the relaxation of sub-Saharan Africa, a extensive proportion of the inhabitants in West Africa is with out entry to electrical power despite the region’s ample natural assets.
The lack of reputable and cost-effective electricity has hindered financial improvement and occupation generation. Offered the little dimensions of the electricity marketplaces in most of the ECOWAS international locations, increasing regional integration can reduced the common charge of offer via economies of scale. It can also market diversification of electrical energy sources, like renewables, enhancing technique reliability and grid balance. This will even so have to have sizeable investment in a steady and interconnected transmission community with minimal transmission losses that can assist load raise, extra flexible cross-border trade flows and the intermittent output of renewable power sources.
The Learn Prepare has determined 28 precedence transmission line jobs with a whole size of somewhere around 22,932 km at an estimated value of USD10.48 billion. The majority of them are cross-border interconnectors while some are countrywide tasks with regional importance. In this write-up I will concentrate on interconnection infrastructure. Federal government ownership (including by public utilities) has been the dominant tactic to financing interconnection jobs in Africa. Inadequate fiscal wellbeing of national utility businesses in common and fiscal constraints of most governments in the area restrict their potential to make investments, even in economically feasible projects. Personal involvement in these projects could assist relieve the financing constraints and bring working experience in task implementation and procedure as well as greater organizational and fiscal self-control.
This report will appear at the probable models for non-public expense in transmission infrastructure in the area, determine some likely worries and think about how they may be resolved.
In the context of cross-border interconnections, personal financial commitment may perhaps get the type of merchant investment decision or unbiased energy transmission (IPT). Neither product has been adopted in Africa to date. Most interconnection assignments in the world have utilised the merchant financial investment design. Less than this product, the service provider buyers develop and run a transmission line. The proprietor of the line sets the conditions and ailments for its entry and generates revenue centered on the total of electrical power flowing along the line and the price variances between the two finishes of the line.
Accessibility to service provider lines is normally proprietary alternatively than open up to all transmission consumers. Quite a few electric power utility firms in sub-Saharan Africa are vertically integrated, point out-owned monopolies. In a lot of instances, their tariffs are established at artificially minimal ranges owing to the revenue level of their shoppers and political concerns. The ensuing deficiency of versatility and dynamics in the relevant wholesale energy marketplaces could undermine the foundation of the small business circumstance and income product for merchant expenditure which is carefully joined to the projected price differentials among two marketplaces.
Also, viability of a service provider line usually is dependent on its skill to manage a monopolistic place to serve as a hyperlink amongst two markets dependent on proprietary access. This design does not seem reliable with the mentioned purpose for the West Africa Electricity Pool, which is, to acquire an integrated unified electrical energy industry.
Impartial Electricity Transmission (IPT)
A different model is to finance, make and maintain the transmission line by way of unbiased electricity transmission (IPT). The IPT model has been determined by the Earth Financial institution as the “business design very best suited to the circumstances in Africa. In essence, it will involve the federal government (or the state-owned utility) tendering a prolonged-expression agreement whereby the IPT (the successful bidder) will be accountable for making and functioning a transmission line in exchange for contractually described payments dependent upon the availability of the line. IPT jobs have been adopted in many nations, though mostly in the context of in-place transmission. Adopting the design for interconnection amongst nations around the world is even so possible to be far more intricate, not minimum thanks to the need to coordinate amongst the governments of the pertinent countries.
In West Africa, the Côte d’Ivoire-Liberia-Sierra Leone-Guinea (CLSG) interconnection task may point to a way ahead. This USD508.2 million job will involve the development of a higher voltage (225 kV) transmission line of around 1,300 km and associated substations connecting the four participating countries’ power devices into the WAPP. The venture is carried out as a result of a regional transmission firm (TRANSCO CLSG) which is responsible for the funding, development, ownership and procedure of the job. TRANSCO CLSG is a unique objective automobile (SPV) owned similarly by the countrywide utilities of the CLSG nations.
To stimulate its usage, the CLSG transmission line will have an open up obtain policy. Energy order agreements have been signed in between Côte d’Ivoire’s nationwide utility and these of the other a few nations around the world. Every single of them has entered into a transmission service settlement with TRANSCO CLSG. The transmission tariff is set applying the postage-stamp methodology so that transmission prices are properly billed to the electrical power purchasers centered on their relative shares of the trade by means of the transmission line. To mitigate the chance of funding shortfall owing to reduced buying and selling volumes, the shareholders of TRANSCO CLSG undertake to pay for any shortfall from trading income.
This pricing methodology the two ensures cost restoration and facilitates trade as a result of the transmission line. The CLSG job is presently beneath construction and is expected to be commissioned in late 2019 or early 2020. Although the CLSG challenge composition does not include any personal ownership of the project enterprise, it is conceivable that a equivalent framework could be adopted to put into practice the IPT product, for case in point by changing authorities-owned shareholders of the transmission SPV with non-public sector task sponsors.
This was in part the framework adopted by the Central American Energy Interconnection Technique (SIEPAC) which had been taken into account in the structure of the CLSG project.4 In SIEPAC, the transmission business, EPR, owns the 1,793 km interconnector (230 kV) which backlinks the ability grids of six Central American international locations. EPR is owned by eight nationwide utilities or transmission firms together with a personal company (ENDESA of Spain) which is dependable for managing EPR. All through the job style and design stage, the alternative of relying solely on non-public sector expenditure was deemed. Nonetheless, it was made the decision that there could not be enough interest from the private sector for these construction thanks to the perceived challenge threats and normal monopoly character of transmission.
However, there seems no purpose why, as a result of right danger administration and with adequate financial incentives, these types of a construction can not be adopted with completely personal ownership. The challenges confronted by the electricity sector in sub-Saharan Africa are properly documented. There are two difficulties in particular to emphasize in the context of introducing private investment decision in interconnection projects, specially IPTs: the regulatory framework and economical viability.
As reported in the Learn Plan, in most of the nations in West Africa, the electric power sector stays vertically integrated with monopoly networks. Though total-unbundling is not a vital pre-issue for IPT, existing legislation and regulation will want to reviewed to enable the IPT to function along with the countrywide utility. The grid code will will need to be set up or revised to offer working processes and rules. In the context of an interconnection challenge, this will require to be done for each individual place it connects and could be cumbersome and end result in a lengthy enhancement direct time.
This difficulty is highlighted in the ongoing North Core Interconnector Project (a 330 kV transmission line connecting Nigeria, Niger, Benin and Burkina Faso). According to the Grasp Plan, the SPV construction adopted in the CLSG task had at first been envisaged also for the North Core job but was not adopted in the stop in check out of the considerable hold off that necessary adjustments to the nationwide authorized frameworks would lead to.
The CLSG challenge previously mentioned has furnished an case in point of how transmission tariffs may be established to meet any minimum profits requirement. Traders will having said that require self-confidence that the contractual payments will be acquired from the transmission line people, which are probable to be countrywide utilities. The common bad monetary well being of the nationwide utilities in the area is probable to be a issue in this regard. It is instructive in this context to take note that several nations in the region have practical experience in addressing this same issue in unbiased electric power tasks (IPP) which may perhaps present valuable lessons for developing IPT tasks.
For illustration, possible credit rating support might be presented through the use of escrow accounts to prioritize payments to non-public sector market participants. Where this is insufficient, governments might offer sovereign assures(or other federal government help) for payment obligations to IPTs. More security might also be delivered by enhancement finance establishments (DFIs). Final but not the very least – political determination On a much more typical notice, getting any huge-scale infrastructure job off the ground will involve political assistance, governing administration motivation and solid general public governance.
For transmission jobs, these components are vital in enabling inter-country negotiations, prioritization of regional projects, helpful deployment of condition assets and coordination of stakeholders these as regulators and utilities. This will call for nationwide governments to just take a very long-term check out on the profit that these jobs will deliver through regional strength trade, in conditions of energy stability, financial effectiveness and eventually the welfare and quality of lifetime of their electorates.
