Ghana Grid Company Limited (GRIDCo) recorded a GH¢584.46 million profit after tax in 2025 as electricity transmitted across the national grid reached a record 25,860 GWh, but the stronger financial performance comes as the company faces a large investment requirement to keep pace with rising power demand.
The performance, reported at GRIDCo’s 13th Annual General Meeting, represents a 4.9% increase in electricity transmitted from the 24,654 GWh recorded in 2024, according to Energy Commission data. The growth reflects rising electricity flows through a system that is becoming important to industrial and commercial activity.
Energy demand was projected to increase by 4.7% in 2025, while Ghana’s generation system remains heavily dependent on thermal and hydro power. That makes the reliability of the transmission network critical to moving electricity from generation facilities to distribution companies, mines and other large consumers.
The challenge, however, is turning higher transmission volumes and improved profitability into sustained capital investment.
GRIDCo’s 2025–2029 tariff proposal identified 15 critical transmission projects with an estimated investment requirement of US$978.35 million. The projects are intended to improve grid reliability, increase transmission capacity for renewable energy and power exports, reduce losses and strengthen voltage stability.
The company has also previously pointed to financial constraints affecting its ability to fully fund maintenance and infrastructure requirements. In its tariff submission, GRIDCo said its tariff remained below the level it considered necessary to recover the full cost of transmission services and support investment.
That financing question is becoming more important as government seeks to expand generation capacity and strengthen energy security.
Energy Minister John Abdulai Jinapor said the government would continue supporting critical transmission investments, including the Eastern Corridor Transmission Backbone, while directing GRIDCo to strengthen preventive maintenance, system monitoring, protection coordination and restoration preparedness.
“Every fault must generate lessons, and every identified weakness must lead to corrective action,” Jinapor said.
GRIDCo has already begun work related to the Eastern Corridor expansion, including plans for a 45-kilometre 161kV transmission line between Asiekpe and Ho. The project is intended to improve the resilience and capacity of power supply along the corridor.
A stronger transmission network can reduce the risk that available generation capacity cannot be delivered to areas where electricity is needed, while additional capacity along strategic corridors could support industrial expansion and improve the system’s ability to accommodate new generation.
Transmission losses also remain an important efficiency measure. Energy Commission data put losses at 3.86% of electricity transmitted in 2024, equivalent to about 951 GWh. GRIDCo has previously targeted keeping losses below the regulatory benchmark of 4.1%.
Abu Jinapor said the government’s objective was to restore GRIDCo’s position as one of Africa’s most reliable, innovative and financially sustainable transmission utilities.
Ghana’s power situation in 2026 also shows the importance of matching the expansion in generation with a stronger transmission network. Although the country has experienced power outages, energy producers are expanding capacity and upgrading existing infrastructure, while the government has indicated that improved generation is creating room for greater electricity supply and exports.
This makes sustained investment in GRIDCo’s network important to ensure that the additional power can be transmitted reliably to businesses and households. As Ghana pushes ahead with industrial expansion, stronger investment across the transmission system will be critical to turning growing generation capacity into dependable power for the economy.
