The hard part of greening a mobile network is that it never switches off

A feasibility study, not a supply contract. What makes it interesting is the choice to go through the national grid rather than put panels on the towers.

The hard part of greening a mobile network is that it never switches off

edotco Bangladesh and FloSolar Solutions Limited have signed an agreement to assess the feasibility of generating renewable energy for the power needs of edotco's telecom tower infrastructure.

The two will jointly evaluate building grid-connected renewable systems, with solar power from a project supplied to edotco's infrastructure through the national grid. edotco announced this in a statement on Sunday.

Who does what

FloSolar will handle selecting the power plant site, the grid connection and the project's development work. edotco will help with site selection and with assessing its own electricity demand.

Al-Batuni Mohammad Saeed Ahmed, country managing director of edotco Bangladesh, said digital infrastructure keeps expanding, and how power reaches it is becoming steadily more important; a large-scale renewable assessment would add a new dimension to emission-reduction efforts.

Mostafa Azim Kasem Khan, founder and managing director of FloSolar Solutions Limited, said telecom networks run twenty-four hours a day, which makes their power supply critical, and that the initiative would help build a long-term supply framework for the network in stages.

Why towers are the difficult case

A tower is a small, constant load in a fixed place that cannot be interrupted. That combination is awkward for renewables: solar is generous in the middle of the day and absent at night, which is precisely when a network still has to carry traffic.

This is why the grid-connected framing matters more than it sounds. The alternative — panels and batteries at each site — has been tried widely across South Asian tower portfolios, and it runs into theft, maintenance across thousands of scattered sites, and battery replacement cycles. Generating at one location and drawing through the grid moves the problem to somewhere it can be managed.

What has not been said

It is worth being precise about the size of this announcement, because the language around corporate renewables tends to inflate.

No capacity figure has been given — no megawatts, no kilowatt-hours. No number of sites or towers. No location. No investment amount and no timeline. And the companies describe this as a feasibility check, not a confirmed supply arrangement.

So what exists today is two companies agreeing to find out whether this works. That is a real step and not a small one, but it is a study.

The context it sits in

Bangladesh's mobile networks are among the country's larger industrial electricity consumers, and tower companies have carried diesel generation for years to cover grid interruptions. Any credible shift of that load onto solar is worth following.

The test to apply later is simple: whether a capacity figure and a site ever appear. Feasibility studies that lead somewhere produce numbers. The ones that do not, quietly stop being mentioned.

The regulatory question underneath

A grid-connected arrangement raises something the announcement does not address: how power generated by one private company reaches another private customer through a national grid it does not own.

That is a licensing and wheeling question, not an engineering one, and it is the step at which corporate renewable projects in this region usually stall. Whether the electricity is sold to the grid and bought back, or wheeled under a bilateral arrangement, changes the economics completely — and the two are governed by different rules.

So the feasibility being assessed is probably as much regulatory as technical. Panels work. Permission is the variable.

What a good outcome would look like

A useful result would be a published figure for how much of edotco's tower load the project could plausibly cover, stated as a share rather than a round number of megawatts. Share of load is the honest measure, because it survives the portfolio growing.
