Why Commissioning Date Matters for Accelerated Depreciation
For a business purchasing an energy installation, the financial implications of the investment extend beyond the ordering process and equipment delivery to the end-use site. An event occurring later in the project lifecycle can be important to the calculation: the precise date on which the system was commissioned into use.
Depreciation normally applies to an asset when it comes into service with the buyer, rather than when an invoice is raised or goods reach the warehouse. The difference between the completion of installation works and the system being put to use can therefore impact accruals in the first year and influence an industrial user’s cash flow from a solar investment.
Commissioning Can Be a Later Event than Equipment Delivery
A commercial solar project consists of multiple phases before the photovoltaic (PV) modules begin to generate electricity. Purchase orders can be issued months in advance, equipment can arrive on site, mounting structures can be assembled and cabling can be completed. None of these activities represent the moment when an asset is brought into active use for the purpose of depreciation.
Commissioning establishes that a system has been made ready to perform its intended function in accordance with the applicable technical and regulatory standards. The supporting documents should therefore be reviewed when establishing the commissioning date for depreciation.
For an industrial buyer, the applicable records could include the commissioning certificate, synchronization and inspection reports, equipment handover documents and any evidence of when the system was made operational. The consistency between these records and the accounting records should therefore be maintained.
The Relevance of the Financial Year
Under the Indian depreciation framework, assets that come into service for less than the specified length of time during a financial year are subject to a reduced depreciation rate.
When a solar project is commissioned near to the end of a financial year, the timing can be relevant to the calculation.
Assume a manufacturing company completes a rooftop solar plant in February. If the system is put to use in that period, the applicable depreciation rate for the year could be considerably different compared to a similar project commissioned at an earlier date.
This distinction is especially important when a buyer is determining the Industrial solar panel installation cost in relation to the tax benefits.
A financial model that assumes full-year depreciation without reviewing the commissioning date would therefore overstate the value of the first-year depreciation benefit.
The Difference Between Delivery and Put-to-Use Date
A common error in modelling project economics is to assume that delivery of equipment is the same as the date an asset is put to use for the purpose of depreciation. Delivery confirms that a buyer has taken possession of goods, but it does not confirm that those goods are ready for the intended purpose.
For a commercial solar installation, the modules could be delivered in November with structural works, cabling, inverter commissioning and approvals continuing through to January. If the system is not connected to the grid and electricity generation has not commenced prior to that point, the January commissioning date will be more relevant to the depreciation calculation than the November delivery date for the modules.
This distinction can be particularly relevant for larger systems where structural works and electrical connection take several months to complete.
The Impact on Tax-Linked Cash Flow
Accelerated depreciation generally does not result in an immediate reimbursement of the equipment price. Instead, it reduces the level of taxable income to which the applicable tax rate is applied, subject to the buyer’s ability to utilize the deduction. The financial benefit therefore depends on the company’s overall tax position.
Suppose two factories acquire similar solar systems at a similar price. One factory commission its system early enough in the year to receive the full first-year depreciation benefit, while the second’s commissioning date falls towards the end of the financial year and falls within the reduced first-year depreciation period.
Although the two systems are identical in terms of equipment, size and electricity production, the tax implications for each factory can be significantly different.
The impact is relevant to the cash flow, since the factory receiving the higher level of depreciation is able to retain more income following the tax calculation. This can be especially relevant to capital-intensive industries where cash retention in the early years can be used to fund working capital, liabilities, maintenance or another capital project.
The Influence of Project Delays
Solar projects can experience scheduling challenges that are unrelated to the PV equipment itself. Construction works, roof preparation, electrical upgrades, transformer capacity, safety inspections, grid-related activities and documentation can all add to the time between purchase and commissioning.
For this reason, a financial model should not be based solely on a projected installation month. Instead, buyers should consider several commissioning scenarios in relation to the applicable depreciation rates and analyze their impact on the overall project economics.
When a company evaluates the Industrial solar panel installation cost, it should therefore consider the capital expenditure and the likely commissioning window for the system.
A useful initial review of a commercial solar project should examine:
- Planned installation completion date
- Expected commissioning and synchronization date
- Financial year in which the system will be put to use
- Applicable depreciation rate and first-year limitation
- Company’s expected taxable income
- Applicable tax regime and other tax restrictions
These considerations provide a more realistic view of the project than the purchase price of the equipment alone.
Depreciation Is Not the Same as Cost Savings
It is also important to recognize that depreciation does not directly reduce the cost of a solar plant. The equipment and installation work must still be purchased and paid for.
The value of accelerated depreciation depends on the ability to apply an appropriate tax shield, which in turn depends on the company’s circumstances.
If a company does not have sufficient taxable income to utilize the full depreciation benefit, it will receive less value from an accelerated depreciation scheme than a company that has a high level of taxable income and can fully apply the deduction.
This consideration is particularly relevant in relation to other capital expenditures. The potential depreciation shield should be analyzed as part of a project’s cash-flow projection rather than incorporated into the quoted Industrial solar panel installation cost.
Documentation Should Be Consistent with the Commissioning Date
The commissioning date should be supported by appropriate project documentation. If the accounting records suggest a certain date while the commissioning certificate, electricity generation records or internal asset register suggests another, this can raise questions in relation to the tax position.
For this reason, developers and industrial buyers should maintain a reliable set of project records showing:
- Installation completion
- Testing and commissioning
- System synchronization
- Commercial or operational start
- Asset capitalization
The specific requirements will vary depending on the structure of the project and the applicable tax regime, so advisors should review the final treatment prior to the submission of a tax return.
Infrax Renewable LTD. can be involved in the technical aspects of a commercial solar project, but the final depreciation position will always depend on the circumstances of the buyer and the applicable law.
Consider Commissioning When Building the Initial Financial Model
The most effective time to incorporate depreciation considerations is prior to the ordering of a solar project. During the initial financial evaluation, the buyer can compare an early-year commissioning scenario with a later date in order to see how changes to the project schedule affect the economics.
For instance, if a change in construction scheduling moves the commissioning date from September to February, this may impact not only electricity generation during the first year but also the level of depreciation available for that year. Since both of these items contribute to the overall return on investment, they should both be factored into the evaluation.
As a result, a buyer can examine the true Industrial solar panel installation cost and arrive at a realistic view of the economics based on actual cash flows rather than a simple quotation.
Conclusion
The commissioning date may not appear to be a significant event to an industrial buyer, but it can be necessary to the calculation of the value of a solar investment. Depreciation is relevant to an asset when it is put to use as part of the generating system, and the timing within the financial year can determine the level of first-year depreciation. As a result, an industrial buyer should examine not only the equipment price and electricity savings but also the potential impact of the commissioning date and applicable tax regime to arrive at a realistic evaluation of a solar project.
