Audit a trading company, a manufacturer, or a retail chain in Nepal, and the core exercise looks broadly similar: verify revenue, check expenses, confirm balances, form an opinion. Audit a hydropower company, and the exercise changes shape entirely. A single project can spend six to ten years in construction before generating a rupee of electricity revenue, involves foreign lenders and equity partners with their own compliance expectations, operates under a government-issued license with a fixed expiry date, and sells its entire output to a single buyer under a decades-long contract. Hydropower audit has effectively become its own specialized niche within Nepal's accounting profession, and for good reason.
Construction-Phase vs Operational-Phase Accounting
The single biggest difference in auditing a hydropower company is that it typically operates in two entirely distinct financial phases. During construction, which can run for years depending on project size and site conditions, the company has essentially no operating revenue, and the audit's attention centers on capital work-in-progress: are costs being capitalized correctly, is the accumulating project cost properly supported by contracts and payment certificates, and is progress being tracked accurately against the engineering schedule. Once the project reaches commercial operation and begins generating and selling electricity, the audit shifts almost entirely toward revenue recognition, tariff compliance, and the ongoing performance of assets that are now depreciating rather than accumulating. An auditor who treats these two phases identically, applying operational-phase thinking to a project still under construction, will miss the issues that actually matter at each stage.
Capitalization of Interest and Borrowing Costs During Construction
Hydropower projects are capital-intensive and heavily debt-financed, often with a debt-to-equity ratio in the range of 60:40 or higher, which means borrowing costs during construction are a genuinely material figure, not a footnote. Under Nepal's accounting standards, interest and other borrowing costs directly attributable to the acquisition or construction of a qualifying asset must be capitalized as part of that asset's cost during the construction period, rather than expensed as incurred. Auditors spend considerable time verifying that this capitalization is being applied correctly: that only borrowing costs on funds actually used for construction are capitalized, that capitalization stops once the asset is substantially complete or once construction activity is suspended for an extended period, and that any interest earned on temporarily invested surplus borrowed funds has been correctly netted against the capitalized amount. Getting this wrong in either direction, capitalizing too much or too little, directly distorts both the project's reported asset value and its eventual depreciation and profitability once operational.
Power Purchase Agreement Revenue Recognition Issues
Once a hydropower project reaches commercial operation, nearly all of its revenue flows from a single source: the Power Purchase Agreement signed with the Nepal Electricity Authority, typically running 25 to 35 years and specifying a tariff structure that often differs between the wet and dry seasons. Revenue recognition under this arrangement needs to track actual energy delivered and the applicable tariff rate for that period, and auditors check this against metering records, NEA settlement statements, and the PPA's own tariff schedule. A more technical issue that has generated real debate and inconsistency across the sector is whether a project falls under IFRIC 12, the accounting interpretation governing service concession arrangements. Where a project meets the specific conditions for a service concession, where a government-linked grantor controls what service is provided, to whom, and at what price, and retains a significant residual interest in the infrastructure at the end of the arrangement, the accounting treatment changes substantially: the project asset is recognized as an intangible right to charge for the service rather than as ordinary property, plant, and equipment, with corresponding effects on how construction-period activity and depreciation are presented. Several audit reports on Nepali hydropower companies have flagged inconsistent or incomplete application of this treatment, making it an area auditors need to assess carefully on a project-by-project basis rather than assume applies uniformly across the sector.
Foreign Loan and Equity Compliance
Given the scale of capital hydropower projects require, many involve foreign lenders, multilateral development banks, or foreign equity investors alongside domestic financing. This brings an additional compliance layer that a purely domestic company wouldn't face. Foreign loans typically require approval routed through Nepal Rastra Bank, and auditors verify that drawdowns, repayments, and interest payments match the approved loan terms and that necessary regulatory approvals were obtained before funds were drawn. Foreign equity investment carries its own approval requirements under the Foreign Investment and Technology Transfer Act, and auditors check that share allotments to foreign investors were properly registered and reported. Repatriation of profits and capital to foreign lenders and investors is guaranteed under Nepali law for hydropower projects specifically, but auditors still confirm that the mechanics of any actual repatriation, exchange rate application, tax withholding, and regulatory reporting, were correctly handled. For projects financed partly through government on-lending arrangements, where concessional financing from an international development bank is channeled through the government or NEA before reaching the project company, auditors also need to trace the on-lending terms accurately, since these can carry different interest rates and conditions than the project company's other borrowings.
Environmental and License Compliance Checks
A hydropower company's entire right to exist rests on a chain of licenses issued by the Department of Electricity Development: a survey license, followed by a construction license, followed eventually by a generation license that is typically granted for 35 years and can be extended to 50 at the department's discretion. Auditors verify that each of these licenses remains current and that the company hasn't inadvertently lapsed into non-compliance with license conditions, since operating without a valid license, even due to an administrative renewal delay, creates a genuine going-concern consideration worth flagging. Environmental compliance sits alongside this: most hydropower projects require an Initial Environmental Examination or a full Environmental Impact Assessment before construction, along with ongoing compliance with the conditions attached to that approval, covering matters like minimum downstream flow requirements, resettlement and compensation commitments, and biodiversity mitigation measures. While auditors are not environmental engineers, they do check that the company has the required approvals on file and that any known breaches or regulatory notices have been properly disclosed and, where financially material, provided for in the accounts.
Common Audit Findings in Hydropower Projects
A recurring pattern shows up across audit reports on Nepali hydropower companies. Cost and time overruns are close to universal in the sector, and when a project runs over schedule, the extra months of construction mean extra months of capitalized interest, inflating the final project cost well beyond original projections, a pattern auditors flag repeatedly. Interest capitalization sometimes continues past the point it should have stopped, particularly when a project reaches commercial operation but management is slow to formally close out the capital work-in-progress account. Governance gaps also appear surprisingly often for companies of this scale, including missing independent directors on the board where the Companies Act requires one. Property, plant, and equipment is sometimes recorded as a single undifferentiated block rather than broken into separately depreciable components, such as civil structures, mechanical equipment, and transmission infrastructure, each of which has a genuinely different useful life, understating or distorting depreciation as a result. And administrative compliance items, such as registration with the Social Security Fund or local municipal business tax offices, are sometimes overlooked entirely amid the complexity of managing the larger project.
Why Hydropower Companies Need Auditors With Sector Experience
None of the issues above are things a generalist auditor encounters routinely. Interpreting borrowing cost capitalization rules correctly requires comfort with long, multi-year construction timelines that most Nepali businesses never experience. Assessing whether IFRIC 12 applies requires genuine judgment about the specific terms of a project's licensing and PPA arrangements, not a mechanical checklist. Coordinating around foreign lender covenants, on-lending structures, and multi-currency exposure requires familiarity most domestic-only audit practices simply haven't built. A hydropower company engaging an auditor without prior sector experience risks a slower, more error-prone first audit at minimum, and at worst, a set of financial statements that don't actually reflect the underlying economics of a genuinely unusual business model.
Conclusion
Hydropower auditing sits at the intersection of financial reporting, engineering economics, foreign investment law, and environmental regulation in a way few other sectors in Nepal do. Understanding how construction-phase and operational-phase accounting differ, how borrowing costs and PPA revenue should be treated, and where the sector's most common findings tend to arise puts a project ahead of most first-time issues. If your hydropower project is approaching commercial operation, bringing on new foreign financing, or simply due for its annual audit, it is worth engaging an ICAN-registered Chartered Accountant with specific hydropower sector experience rather than a general practice auditor, the difference in audit quality and efficiency is usually significant.
