Ghana has made vital progress over the previous 10 years in growing electrical energy technology and entry. This has supported larger ranges of financial development. Nevertheless, beneath these enhancements lies inefficiencies, together with terribly excessive distribution losses. Electrical energy can also be fairly costly in Ghana. If not addressed, these points might derail Ghana’s improvement agenda.

As international locations transition their economies to ones that use much less carbon, they should construct balanced power programs. These should be anchored on excessive power safety, common entry at inexpensive costs and low emissions.

Ghana started reforming its power sector within the mid-1990s to encourage competitors and effectivity. Unbiased energy producers have been launched to extend thermal technology capability utilizing crude oil and pure fuel. Ghana had been closely depending on hydroelectric energy from the Akosombo Dam. When rainfall patterns started to vary within the mid-1980s with accompanying low water ranges, power coverage shifted.

The reforms additionally launched efficiency contracts and different power effectivity initiatives to decentralise the worth chain, which had been monopolistic. This was additionally a pre-condition by improvement financiers such because the World Financial institution.

Between 2000 and 2019, electrical energy technology capability elevated at a charge of 6.4% a 12 months from 1,358 megawatts (MW) to 4,695 MW. Provide capability has almost doubled because the 2013 energy disaster. On the identical time, system peak demand grew at a 4.6% annual charge from 1,161 MW to 2,804 MW.

The rise in energy technology supported Ghana’s economic system. The economic system grew in actual phrases by 6.67% a 12 months between 2011-2019. Electrical energy demand is estimated to have grown at 7%-10% a 12 months since 2010.

Regardless of power technology being in extra of demand, energy stays costly and unreliable, and has turn into a constraint on doing enterprise within the nation.

We lately performed analysis during which we analysed how the nation’s altering energy combine impacts power safety, power fairness and environmental sustainability. The three are known as the “power trilemma”.

We discovered that Ghana has proven vital enchancment from 2000 to 2019 in power safety and power fairness. It has made marginal enhancements on environmental sustainability. Nevertheless, these enhancements masks some inefficiencies that want addressing if the nation is to have a extra resilient electrical energy sector.

Rebalancing power sources

The World Power Council’s Power Trilemma Index ranks Ghana among the many prime 10 international locations which have improved on power safety, fairness and environmental sustainability. Solely two different African international locations – Kenya and Ethiopia – made the highest 10.

The shift from hydro to thermal has helped Ghana to extend power safety. Whereas hydro accounted for 68% of electrical energy generated in 2000, it is now 36%. On the identical time, the nation has elevated thermal technology capability to 64% of the combination. Ghana additionally has a greater steadiness of sources for gasoline for electrical energy technology. In 2019 Ghana procured 63% of fuel from its personal offshore fields and one other 37% through the West African Gasoline Pipeline. Gasoline provide reliability is predicted to enhance once more when the Tema LNG mission is accomplished.

Renewable power makes up lower than 1% of the the electrical energy combine excluding hydro. There are a variety of causes for this. They embody a scarcity of financing for renewable initiatives and a normal lack of public consciousness of renewable power applied sciences. Ghana can also be wanting skilled personnel to put in and handle renewable initiatives.

On fairness, 85% of the inhabitants has entry to electrical energy in 2020. This makes Ghana one of many African international locations which might be probably to attain 100% common entry by 2030.

Regardless of the advance in electrical energy entry, we additionally discovered that adjustments to the power combine, and the ensuing electrical energy tariff construction, have been masking inefficiencies within the distribution system.

The tariff construction locations a burden on some client classes. These embody business and industrial customers. This creates unintended penalties of unpaid payments and electrical energy theft, hampering full value restoration. In the end, this negatively impacts on additional investments that would enhance electrical energy provide.

Power safety isn’t just about elevated energy technology and availability. It’s about your complete worth chain, from technology to transmission and thru to distribution. Our evaluation reveals a scarcity of funding within the nation’s distribution infrastructure.

The result’s {that a} persistent 25% of electrical energy generated in Ghana is misplaced on the retail finish. These are attributable to dilapidated infrastructure (technical losses) in addition to electrical energy theft or business losses. Ghana’s losses are greater than double the sub-Saharan Africa common of 12%.

The state of distribution infrastructure has implications for integrating different variable renewable power sources into the grid by making them much more costly to attach. For shoppers, such losses imply energy outages are more likely to proceed.

Environmental sustainability is a composite measure of ultimate power depth (the power used to provide a specific output), low carbon power technology and CO₂ emissions per capita. Thermal technology capability now has the next share of the power combine however its gasoline sources have improved, shifting from heavy gasoline oils to fuel. Nevertheless, there has additionally been much less room for low-carbon power technology. The goal for renewable power technology was 10% by 2020, and has now been prolonged to 2030.
