The Cost of IoT in a Plant: Components and Budgeting

The first question almost every manager asks about IoT is cost. The answer often feels vague, because IoT cost does not come from one item. There are devices, installation, connectivity, software, and the people to run it. Understanding the components makes budgets realistic and prevents surprises mid-project.

This article breaks down the cost of implementing IoT in a plant, gives an example pilot budget, and shows how to judge whether the investment is worthwhile.

Cost components

• Field devices. Sensors, energy meters, or other measuring devices. The number of measurement points is the largest cost driver.
• Gateways and connectivity. Needed for Modbus devices or sites without Wi-Fi. Includes monthly cellular data if using 4G.
• Installation. Technicians, cabling, panels, and accessories. Cost depends heavily on site conditions and distances between points.
• Platform subscription. A monthly fee for data storage, dashboards, alarms, and analytics.
• Integration. If data must reach ERP, SCADA, or other systems.
• Training and support, so the system actually gets used.
• Maintenance. Calibration, battery or sensor replacement, and periodic checks.

An example pilot budget

An illustration: monitoring energy on a plant's five largest panels. Device and platform prices below use the prices listed on the INCLUDE site at the time of writing. Installation cost is only an assumption and depends heavily on the site.

Component	Assumption	Estimate
Devices	5 energy meters, from Rp1,250,000 each (single-phase variant)	From Rp6,250,000, one-off
Installation	Assumption, depends on panel conditions	Per site survey
Platform	Starter plan, up to 10 devices	Rp29,000 per month

Three-phase meters for large panels are priced differently, so ask for a quote for the points you choose. What matters in this example is the structure: a pilot does not have to be expensive, and the largest costs are usually devices and installation, not the platform.

Often-forgotten costs

• Internal team time to accompany surveys, installation, and testing.
• Cellular data for 4G gateways, running every month.
• Panel changes, such as adding CTs or mounting space.
• Extra quota as the number of devices or users grows.

Judging viability: payback

The simplest way to judge viability is to compare total cost with the savings or losses it prevents. For example, if energy monitoring helps eliminate kVArh charges, shift load out of WBP hours, or find compressor leaks, the monthly saving can be compared directly with device and subscription costs. The InEnergy solution page has a payback calculator you can fill with your own plant's numbers.

Beyond direct savings, there are benefits that are harder to count but real: team time no longer spent reading meters, machine faults caught earlier, and faster decisions because data is available any time.

Start small, prove it, then expand

1. Pick one clear problem with a measurable cost impact.
2. Install just enough measurement points to answer it.
3. Measure results over one to three months.
4. Use the results as the basis for an expansion budget.

This approach lowers risk and makes the next budget request rest on numbers from your own plant, not vendor promises.

An illustrative payback calculation

An example with assumptions: a plant pays about Rp14 million a month in excess kVArh charges due to low power factor, as illustrated in our article on PLN kVArh charges. A five-point pilot finds that two capacitor bank steps are not working. Once repaired, the kVArh charge disappears. In this scenario, device and installation costs pay back within the first months, and the platform subscription afterwards is a small cost to stop the same problem quietly returning.

Not every project finds savings that large. So choose a pilot problem whose cost already shows on the bill or in breakdown records, so results can be measured clearly.

Frequently asked questions

Do we have to buy every device from one vendor?

No. An open platform accepts devices from many brands. Existing devices, such as Modbus power meters, can often be used without replacement.

Are there monthly costs?

Usually yes, for the platform subscription and, if using 4G, data. The INCLUDE Community plan is free for trying things out with 3 devices.

How long does a pilot take?

Installing the first points can take just days. Meaningful results usually show after one to three months of data.

Planning a budget with INCLUDE

Prices for every INCLUDE platform plan, from free to Enterprise, are published openly on the pricing page. IncludeBox and IncludeGateways devices are available when needed, and existing devices can stay in use. For projects that need surveys and integration, the INCLUDE services team helps define scope and budget. Early-stage considerations are also covered in starting monitoring without replacing equipment.
