Following months of deliberation, RAAEY, the Regulatory Authority for Waste, Energy and Water, has reached decisions on WACC levels for power grid operator IPTO and distribution network operator DEDDIE/HEDNO, setting the former’s at 7.51 percent, for 2023 to 2025, and the latter’s at 7.66 percent for 2023 and 2024, energypress sources have confirmed.
Based on these decisions, IPTO’s average WACC level for the four-year regulatory period, covering 2024 to 2027, works out to 7.16 percent, while the four-year regulatory period average for DEDDIE/HEDNO is 7.11 percent.
The discrepancy in WACC levels resulted from different borrowing-cost coefficients applied to a WACC formula used by RAEEY. All other factors that were taken into account, including country risk and cost of capital, were identical.
IPTO initially sought a higher WACC rate, pushing for its cause from as far back as last year, citing unfavorable changes in the economic environment, including inflation and interest rate increases.
Just recently, RAAEY set a WACC rate of 7.85 percent for gas grid operator DESFA, covering the entire four-year regulatory period (2024-2027), and an 8.57 percent WACC rate for DEPA Infrastructure, limited to 2023.
