A busy battery fleet still has to earn its days

In 2020, as finance director, I approved a management dashboard showing ₹12.6 crore of quarterly collections under a rental-performance heading. The operating team wanted a timely account before the full closing process, and I regarded the bank reconciliation as a strong basis for it. Asha Dezqarthi questioned the meaning of the total. Her review separated ₹9.4 crore of earned amounts from ₹3.2 crore of refundable customer deposits. Receipt was established; earning the whole amount was not.

I had approved the presentation and needed to correct its interpretation. The commercial sponsor argued that the money had genuinely arrived and that changing the heading would make a strong collection quarter harder to communicate. I agreed that the cash result was real, but not that it could carry an income conclusion. We retained the collections view and added the purpose and continuing obligation beside each component. The customer deposits did not become available performance merely because management preferred a single number.

The correction reached the management account before statutory closing. We incurred ₹27 lakh for review and the supporting record, with the responsible accounting process retaining authority over formal treatment. No cash recovery, theft or lost customer money is claimed. The bank balance had not changed because the presentation was corrected. What changed was the meaning management was entitled to take from it and the evidence required before a receipt appeared in an earned-activity discussion.

The immediate cost included revisiting a dashboard I had promoted as a faster route to clarity. Finance had to explain why a reconciled cash total could still support the wrong conclusion. I would now define the decision a management measure is intended to support before approving its layout and timing. A timely number can be valuable, but its speed does not remove the obligation to say what it represents. The lesson was personal: I had checked that the total was real more carefully than I had checked the inference it invited.

The FY 2026 fleet review showed 31,500 scheduled unit-days. Commercial colleagues used the busy calendar to support a ₹16 crore proposal for twenty additional battery units. The existing fleet comprised 120 units, giving 43,800 nominal unit-days in a 365-day year. I asked for the scheduled days to be connected to the contractual earning event before interpreting them as evidence that the fleet needed to expand. A cell occupied in a planning calendar was not necessarily a day the customer had agreed to pay for.

The review separated 24,400 billable days, 3,100 movement days, 2,500 unpaid-hold days and 1,500 service days. The latter three groups totalled 7,100, and all four reconciled to 31,500. The nominal 43,800-day capacity was a calendar illustration, not a claim that every unit could be deployed safely or continuously. These counts also said nothing by themselves about power output or delivered energy. Operations and engineering retained those assessments.

The commercial head argued that additional units would reduce scheduling pressure and allow the team to pursue opportunities it was turning away. I asked which pressure reflected paid demand and which might be reduced by handling movement and hold periods differently. The CEO deferred the ₹16 crore acquisition proposal and approved ₹1.1 crore for calendar, logistics and commercial review. That expenditure funded investigation and revised arrangements, not a promise that every unpaid day could become revenue.

We kept the expansion option open for a further evidence-based decision. The result was not ₹16 crore saved, because the investment had not been approved and could still be proposed later. Nor did we claim a measured utilisation improvement before the review had produced one. I would establish the earning-state definitions when a unit enters the fleet, so that growth discussions do not begin from a schedule whose apparent fullness finance must later reinterpret. A rental business needs enough equipment to serve demand, but the financial case should distinguish earning demand from the resource consumed in getting ready to serve it.

A 2024 review examined a battery-asset cohort with a ₹30 crore carrying amount and five remaining years in the illustration used for planning. The account assumed ₹12 crore residual proceeds. On a simple straight-line prospective basis, that left ₹18 crore over five years, or ₹3.6 crore annually. The asset team wanted to retain the assumption because an earlier supplier indication had referred to a possible repurchase route. I asked what evidence supported the proceeds under the actual conditions attached to that route.

Qualified technical and accounting owners reviewed condition, remaining-use assumptions and the available commercial evidence. The supplier indication was conditional and was not a binding cash receipt for the amount in our model. The reviewed residual estimate became ₹4.8 crore. Holding the stated ₹30 crore carrying amount and five remaining years constant for the comparison, the prospective annual illustration became ₹5.04 crore: ₹25.2 crore divided by five. The ₹1.44 crore increase was an expense illustration under those assumptions, not an immediate cash payment or a new loss of physical capacity.

Some managers preferred a slower change because the higher charge made the rental economics less comfortable. I rejected choosing the residual assumption from the expense we wanted the business to report. The responsible accounting process determined the actual treatment and any additional assessments required; the numerical example did not prescribe a universal policy or settle every asset's condition. We retained the comparison in the management account with its scope and evidence stated.

The consequence was a less favourable forward cost view and a requirement to revisit pricing and investment assumptions. It did not establish that the assets would ultimately be sold for exactly ₹4.8 crore. That remained an estimate requiring future review. I would ask for the commercial conditions behind a residual figure when the original investment paper is prepared, rather than wait until the figure has become part of the expected margin. A finance leader should be able to explain why an estimate is credible without first explaining why the preferred result needs it.

A 2023 twelve-month project proposal showed ₹8.4 crore service revenue and ₹7.1 crore defined direct costs, implying ₹1.3 crore contribution before company overheads, financing and tax. The customer scope required repeated movements between work areas, but the cost model had included fewer relocations than the service team expected. The sales sponsor wanted to preserve the quote because the account was commercially important. I asked operations to describe the agreed deployment sequence before finance defended the margin.

The revised direct-cost forecast was ₹8.3 crore, an increase of ₹1.2 crore. At the original price, the defined contribution would have been ₹0.1 crore, not ₹1.3 crore. That difference did not arise from an accounting allocation of corporate overhead. It came from work the proposal required but the first model had not fully included. Engineering and service owners retained responsibility for deployment suitability and safe handling; finance did not reduce their scope to make the quote fit.

We returned to the customer with the sequence and the cost consequence. After negotiation, the customer accepted ₹9.1 crore for the agreed scope. Forecast contribution on the ₹8.3 crore cost view was therefore ₹0.8 crore. The commercial team gave up the earlier opening price and accepted a more difficult negotiation, while the business retained responsibility for the service it had described. This was an amended agreement before delivery, not a retrospective attempt to charge for work already promised without qualification.

The completed period recorded ₹9.1 crore earned service revenue and ₹8.55 crore defined direct costs, leaving ₹0.55 crore contribution on that boundary. We kept the ₹0.25 crore shortfall against the revised contribution forecast in the review. That amount was not net profit, and the remaining company costs were not silently treated as zero. I would bring the deployment sequence into the first commercial model next time. The case showed that finance can help preserve a viable agreement without claiming that a corrected forecast makes execution certain or that a larger contract price is value created on its own.

A defined twelve-project review in 2025 recorded 1,000 MWh of purchased input energy and 820 MWh delivered within the stated customer measurement boundary. The planning account had costed the input-energy component by applying a uniform illustrative ₹6 per kWh to the delivered quantity. That produced ₹49.2 lakh. Applying the same rate to the purchased quantity produced ₹60 lakh, matching the energy component examined in the review. The ₹10.8 lakh difference exposed a mismatch between the quantity being costed and the cost being described.

The commercial team wanted to use the delivered measure because it related directly to the customer's service. I agreed that it mattered, but the supplier-energy expense arose from the input quantity. Engineering colleagues cautioned that the 180 MWh difference could not simply be labelled battery conversion loss. Auxiliary loads, measurement boundaries and changes in stored energy also required consideration. Finance kept that qualification rather than using the ratio to announce a universal efficiency figure.

We revised the project-cost account to use the appropriate measured quantity for this energy component and asked the responsible technical owners to explain the remaining boundary questions. On the limited figures, ₹60 lakh divided by 820,000 delivered kWh is approximately ₹7.32 per delivered kWh. That is an allocation of the reviewed input-energy cost, not a customer tariff, a complete service cost or a technical performance certification. Demand charges, taxes, transport and other costs were outside this particular illustration and still needed their own treatment.

The correction reduced the apparent contribution of the reviewed work. It did not prove that every project should be repriced by the same amount or that the entire energy difference could be removed. I would agree the cost and measurement boundaries before the first proposal model is circulated. Familiar units make a calculation look straightforward, but the financial question is which quantity actually gives rise to the expense. A CFO can insist on that connection while leaving physical interpretation with the people qualified to assess it.
