The Tower Stayed Online. Costs Climbed.
An energy review for Nigerian TowerCo and telecom decision makers.
A tower can meet its availability target and still need a closer look at its energy costs. Consider an illustrative October review: the site stayed online throughout the reporting period, yet its power bill increased. Finance wants an explanation. The next fuel allocation is due.
Finance and Operations need the same operating record to establish what changed. A higher bill could reflect more site load, a change in energy prices or a greater reliance on generator power. It could also reveal an operating pattern that deserves investigation.
For leaders managing towers across Nigeria, October is a practical moment to examine those differences before the next maintenance and spending decisions.||
Separate the price change from the operating change
Start with comparable periods and a complete enough record. Check total energy consumed, each source's contribution and the costs used in the calculation. Identify equipment additions, outages and gaps in monitoring that could distort the comparison.
If consumption rose after equipment was added, part of the increase may be expected. If energy use stayed similar but generator contribution increased, examine the supply and operating sequence. Confirm which organisation carries the relevant energy and maintenance costs under the site's arrangements.
This gives Finance and Operations a specific explanation to test, rather than treating every increase as a maintenance failure.
A Lagos example worth examining
At Kikspro Meats and Farmers Market, a Lagos cold-chain business, enee.io's published case study reports that diesel supplied 16% of energy consumed but accounted for almost half the monthly energy cost. The investigation identified generator-use and switching issues despite substantial grid availability. [1]
Working with Boyls Engineering, monitoring was combined with changes to generator dispatch and automatic transfer switching. This was a cold-chain installation. Its relevance to tower operations is the investigation: establish how power-source choices affect the bill before forecasting what a particular site can save.
Examine why the generator keeps running
For a tower site, place generator events alongside grid information, battery behaviour and site load. If generator operation continues after grid supply returns, ask the engineer to establish the reason.
Supply quality, charging requirements, transfer settings or operational delays may explain the sequence. A start or stop event alone cannot establish whether runtime was unnecessary. Check the engineering records and operating requirements before changing settings.
Prioritise repeated patterns and material costs. Compare sites with similar configurations and operating conditions, then assign the investigation to a named owner. Use the site's measured fuel consumption and applicable prices when assessing the cost of any runtime that can be avoided.
Give seasonal maintenance an operating record
As harmattan preparation progresses, connect local conditions with the equipment maintenance plan. Cummins advises more frequent maintenance for generators operating in hot or dusty conditions. Apply the relevant manufacturer's guidance and inspection findings at each location. [7]
Review repeated warnings with the maintenance team. A recurring alert should lead to a documented investigation and a follow-up review of the readings after work is completed. That record helps establish whether the operating pattern changed.
Bring the evidence into the next decision
enee.io brings monitored energy-source and consumption information into site reporting. Proteus supports comparisons across monitored locations and reviews of recurring issues. Teams can use those records to prioritise technical investigation and support maintenance or investment discussions. [2] [3]
For the next review, select one site with a rising power bill. Record the suspected driver, the evidence available and the action needed to verify it. Agree who will investigate and when the team will review the result.
Bring that site question to an enee.io demonstration. Which operating pattern would your team most want to understand before approving the next tower power spend?
