Ghana's Institute for Energy Security and Public Regulatory Policy (INSTEPR) has called on the Public Utilities Regulatory Commission (PURC) to suspend its proposed 3.49% increase in electricity tariffs for the third quarter. INSTEPR asserts the PURC’s own data does not support the announced increases for electricity and water consumers. This challenge puts pressure on the PURC to publicly justify its tariff adjustment decisions.
INSTEPR, in a statement dated June 25, 2026, highlighted that key economic variables affecting utility costs either moved marginally or declined. The cedi depreciated by only 0.20%, inflation decreased by 17.74%, and the Weighted Average Cost of Gas saw a 1.58% downward adjustment. These figures, according to INSTEPR, contradict the rationale for raising tariffs, specifically a 3.49% increase for electricity and a 0.85% increase for water.
This dispute occurs as Ghanaian households and businesses grapple with high living costs. Electricity and water tariffs directly impact consumer spending and business operating expenses. Even small increases can erode disposable income for families and raise production costs for industries, affecting competitiveness. The need for transparent and consistent utility pricing is crucial for economic stability and public trust.
The Institute for Energy Security and Public Regulatory Policy has formally appealed to the PURC. INSTEPR stated, "INSTEPR will appeal to the PURC to suspend the proposed third quarter tariff adjustment to provide relief to Ghanaians facing high costs of living." They also urged the regulator to adopt a transparent and consistent methodology for future quarterly tariff adjustments.
The PURC's Quarterly Tariff Adjustment mechanism tracks changes in four main variables: the cedi-dollar exchange rate, inflation, electricity generation mix, and fuel costs, primarily natural gas. This mechanism prevents utility companies from either under-recovering or over-recovering revenue. Under-recovery can compromise service quality, while over-recovery burdens consumers unnecessarily.
INSTEPR's main concern is not the mechanism itself, but the PURC's inconsistent application. The Institute noted the Commission sometimes uses historical data and other times applies forward rates for calculations. This inconsistency makes it difficult for analysts and consumers to understand the basis for tariff adjustments. The resulting lack of clarity undermines public confidence in the regulatory process.
For the PURC, the immediate task is to provide a clear explanation for the 3.49% electricity and 0.85% water tariff increases. The Commission must demonstrate precisely how these percentages were calculated and disclose any other influencing factors. Such transparency is vital for the credibility of utility regulation. Consumers may not always welcome price hikes, but they are more likely to accept them when the rationale is clear and supported by evidence.
This situation underscores a broader regulatory challenge. The PURC could enhance transparency by publishing a detailed tariff adjustment template after each quarterly review. This template would show the weight assigned to each variable and its impact on the final tariff. This approach would allow independent analysts, civil society groups, and the public to assess the justification for tariff changes, fostering greater trust and accountability.
