Intercom Switch Investment Limited: Engineering Nigeria's Power and Automation Future

For eighteen years, one Nigerian engineering firm has worked largely behind the scenes, building the control panels, power systems and automation setups that keep industrial and commercial facilities running. Intercom Switch Investment Limited, known within the industry as ISIL, started out specializing in electrical control panels. Today, it designs, installs and maintains power and automation systems for clients across oil and gas, manufacturing, healthcare, data centres, mining, utilities and residential projects.

The Story Behind "Power Is Our Solution"

Founded in 2008, ISIL has spent 18 years building expertise in electrical engineering, power systems, industrial automation and related engineering services in Nigeria. What began as a specialism in electrical control panels has grown into a broader engineering practice: control panel building and installation, electrical engineering consultancy, and full project execution for clients in oil and gas, manufacturing, commercial facilities, healthcare, data centres, mining, utilities and residential projects.

About ISIL

ISIL is an engineering company built around electrical systems and power infrastructure, switchgear, industrial automation, mechanical services and engineering consultancy, with maintenance support delivered as part of that wider capability. The company works with businesses and organizations that require reliable electrical and power systems for their facilities and operations. Its capabilities cover projects from electrical design and control panel development through installation, system integration and commissioning, supported by structured post-project training that helps extend the operational life of what is delivered.

Vision and Mission

ISIL's vision is to build a strong position in sustainable and intelligent power distribution while contributing to improved reliability and efficiency across industrial and commercial operations. Its mission is to deliver quality electrical engineering solutions through technical expertise, innovation, integrity and a commitment to dependable project delivery. Five values sit behind those objectives, integrity, excellence, innovation, reliability and focus, shaping how the company approaches its projects, client relationships, engineering work and business development.

What ISIL Does

ISIL's capabilities span several areas of engineering and technical support, led by the consultancy work that shapes every project before it begins.

1. Consultancy Services

ISIL's consultancy work covers technical assessment and advisory requirements, forming the starting point for most engagements: inspection, troubleshooting, energy assessment, network analysis, proposal development and site investigation. The company also supports projects involving smart energy metering, IoT integration and remote monitoring where those technologies suit a client's requirements.

2. Electrical Engineering

ISIL's electrical engineering services cover the design and implementation of electrical infrastructure, including electrical system design, control panel building, automation, power and energy engineering, renewable energy engineering and electrical safety engineering, engineered around the operating conditions each client actually works in.

3. Industrial Automation

ISIL also works in industrial automation and control systems, including synchronization. Its capabilities include PLC programming, SCADA systems, control logic integration, synchronization and related automation solutions that monitor and adjust industrial processes with minimal manual input. By integrating automation into electrical and industrial systems, the company helps clients improve visibility, control and operational efficiency.

4. Mechanical Services

The company's mechanical services support power generation and related equipment, including transformer winding, generator installation, repair and servicing, generator refurbishment and spare parts supply, covering both diesel and gas-powered generators. The goal is to support the operational requirements of facilities that depend on power generation infrastructure.

5. Overhauling and Maintenance

ISIL also provides maintenance and overhaul services for existing equipment and systems. Depending on the equipment and project requirements, this can include lubrication, cleaning, retrofitting, disassembly, inspection, troubleshooting and replacement of faulty components, extending the useful life of existing equipment where it is technically and commercially appropriate to do so.

The ISIL Engineering Process

ISIL approaches projects through four broad stages. Inspection covers understanding the client's requirements, assessing existing infrastructure and identifying technical and operational considerations. Design covers developing engineering designs, specifications and system configurations based on what that assessment finds. Execution covers installing equipment, integrating systems and carrying out the engineering work in line with project specifications and safety requirements. Commissioning covers testing, validating and handing over completed systems. Requirements gathering, equipment sourcing, technical testing, installation, quality checks and post-project support run underneath all four stages.

Who ISIL Works With

ISIL serves organizations across a range of industries that need dependable electrical infrastructure and technical engineering support, including oil and gas, manufacturing, commercial facilities, healthcare, data centres, mining, utilities and residential projects. Over the years, the company has worked on projects involving electrical infrastructure, power systems, automation, generation equipment and maintenance. Where client relationships are publicly disclosed and approved for publication, ISIL highlights selected projects and organizations as part of its corporate communications and project portfolio.

ISIL by the Numbers

Since its founding in 2008, ISIL has built an 18-year engineering track record. Company figures put the total at more than 500 projects delivered, more than 200 satisfied customers and more than 8 industries served. ISIL also works with established equipment manufacturers, technology providers and industry partners to source equipment relevant to specific projects, with a portfolio that includes equipment and technologies associated with ABB, Siemens, Acrel, ComAp, Baudouin and P.I.T. The nature of each relationship varies by brand and product category, spanning supply, distribution and technology arrangements, so ISIL presents each according to its specific status rather than grouping them under one partnership label.

Leadership

ISIL's leadership is grounded in engineering. The company was built on an engineering vision first, with its business structure shaped around that foundation.

Beyond Engineering: The ISIL Store

ISIL's activities also extend into the supply of tools, equipment and technical products through the ISIL Store, which serves engineers, technicians, contractors and businesses that need professional equipment for technical work. Its product range includes P.I.T. cordless power tools such as drills, demolition hammers, cutting saws, grinders, drilling and fastening equipment, and masonry-cutting tools, alongside selected Acrel smart energy metering equipment and other testing and safety-related products. The store runs as a product and equipment retail channel alongside ISIL's engineering business, which focuses on project delivery, installation, maintenance and automation.

Building for the Future

Eighteen years on, ISIL says its focus remains the same: electrical engineering, power infrastructure, automation, generation and the technical support that holds it together. As power systems in Nigeria lean further into automation, digital monitoring, renewable energy and smarter management technologies, the company says it intends to keep solving the practical problems clients bring to it, under a guiding philosophy it sums up in three words: Power is Our Solution.
