Financial Structure and Tariff Model

The Kohala Hydropower Project is structured under a Build, Own, Operate, and Transfer (BOOT) framework, a common model for large-scale infrastructure developments in Pakistan’s energy sector. Under this arrangement, the operator, China Three Gorges Corporation, assumes significant financial and operational responsibilities during the initial phases of the project's lifecycle. This structure allows for efficient capital deployment and risk distribution between the host country and the foreign investor. The BOOT model ensures that the operator maintains control over the asset for a defined period, optimizing performance before transferring ownership back to the state. The financial viability of the project is underpinned by a detailed tariff structure designed to balance investor returns with consumer costs over the project's 30-year lifespan. The tariff is segmented into two distinct phases to reflect the changing financial dynamics of the asset. During the first 12 years, the tariff is set at 8.9 cents per unit. This higher initial rate helps to service the debt and cover the higher operational costs associated with the early years of the run-of-the-river, high-head facility. Following this initial period, the tariff decreases to 5.1 cents per unit for the remaining 18 years. This reduction reflects the stabilization of costs and the nearing completion of debt servicing. The average tariff over the entire 30-year life of the project is calculated at 7.9 cents per unit. This average provides a stable benchmark for financial planning and energy cost projections in the Azad Kashmir region. The financial model is designed to deliver a 17 per cent return on equity for the investors, making the project attractive to international capital. This return rate is critical for securing the necessary funding for the 1124 MW capacity installation. The tariff structure and return on equity are key components of the agreement finalized in 2020, which was formally signed by Pakistani Prime Minister Imran Khan and the Chinese ambassador.

How does the tariff structure compare to regional standards?

The financial framework for the Kohala Hydropower Project is structured around a Build, Own, Operate, and Transfer (BOOT) model, designed to attract long-term investment from the China Three Gorges Corporation. Under this arrangement, the project is financed through a combination of equity and debt, with the tariff structure serving as the primary mechanism for revenue generation and risk mitigation. The agreed-upon average tariff is set at 7.9 cents per unit, a figure that reflects the high-head nature of the facility and the associated capital expenditures required to harness the 316-meter drop near Kohala in Azad Kashmir. This tariff rate is critical for ensuring the project's bankability, particularly given the proposed capacity of 1124 MW and the run-of-the-river technology employed, which often requires significant civil works relative to output. The financial model targets a 17 per cent return on equity (ROE), a metric that balances investor expectations with the cost of capital for the Chinese operator. This ROE is achieved through the 30-year concession period, during which the China Three Gorges Corporation will own and operate the facility before transferring it to the Pakistani government. The tariff structure is designed to provide a steady cash flow that covers operational expenses, debt servicing, and the targeted equity returns, thereby reducing the financial risk for the investor. This approach is consistent with other major hydropower initiatives in the region, where long-term power purchase agreements (PPAs) are used to stabilize revenue streams. Comparing this structure to regional standards, the 7.9 cents per unit tariff is competitive within the context of Pakistan's hydropower sector. It reflects the specific characteristics of the Kohala site, including its high head and the associated efficiency gains. The 17 per cent ROE is also in line with the returns sought by international investors in the region's energy infrastructure, providing an incentive for the China Three Gorges Corporation to proceed with the project. This financial arrangement supports the broader goal of expanding Pakistan's renewable energy mix, leveraging the water resources of Azad Kashmir to generate consistent power output. The BOOT model ensures that the operator bears the initial capital risk, while the government benefits from the long-term energy supply and eventual asset ownership.
