Case study: Oman Electricity secures 90 grid stations
Having encountered a fatality at one of its remote sites, the Oman Electricity Transmission Company needed to find a quick solution and secure its 90 grid stations
The Oman Electricity Transmission Company (OETC) recently contracted New Zealand-headquartered Gallagher Security to come up with a solution to secure access to its remote sites.
Based in Muscat, the OETC owns and operates the main electricity transmission network, transferring electricity from generating stations to distribution load centres in all governorates of the Sultanate of Oman.
OETC supplies electricity to more than 4.6 million people and protecting the company’s assets while ensuring the safety of the public is pivotal for smooth operations.
With 90 grid stations in remote locations, identifying and responding to unauthorised intrusions in a timely way was a challenge for OETC.
“It can take up to an hour to reach some of our sites after an alarm is triggered. By then it’s too late, the intruder is gone,” says Muralinath Gudimella, ESC Gulf consultant and lead engineer at OETC.
Adding to the worry were members of the public entering the sites to have picnics, unwittingly risking injury or even death. After a fatality when someone interfered with an electricity transformer, it was evident the OETC required a robust perimeter security system to deter intruders, manage risk, and protect the public from harm.
In partnership with local consultant ESC Gulf, and security contractors Majees Technical Services and Mustafa Sultan Enterprises, a Gallagher Security monitored pulse fencing solution was chosen to protect OETC’s remote sites. Certified contractors installed the system, while Gallagher provided support and oversight of the installation and commissioning works.
Thanks to the Gallagher fencing solution, perimeter breach attempts are deterred by an energised pulse, delivering a short but safe shock to intruders. The monitored wires detect unauthorised entry or exit and trigger instant alerts.
The Gallagher Z20 Disturbance Sensor in use at the gate heightens perimeter security by ensuring continuous monitoring and detection of vibration or movement of the gate when it is closed and the system is in an armed state.
Efficiently and reliably managing access to OETC sites has given the company the control it needed. The ability of Gallagher technology to integrate with CCTV cameras, automated lighting and a remote monitoring system, further ensures a safe and secure environment.
Gallagher’s perimeter products are designed to comply with international safety and electromagnetic compatibility standards. These standards set out the safety requirements for the design, installation, and operation of pulse fencing and associated equipment.
“With a fully monitored solution we have been able to reduce the number of guards we need and ensure they’re working where they’re most needed,” Gudimella says.
The implementation has not only helped OETC to ensure the safety of the public, but has also managed to save money. Gallagher perimeter control solutions are now under construction or completed at 43 of the remote grid station sites — including over 25 kilometres of monitored pulse fencing. As a result, unauthorised entry to these sites has been reduced to zero.
“The OETC now has peace of mind that assets at its remote sites are protected, while being secure from unauthorised access — ultimately keeping people safe from harm,” a company spokesperson says.
“We had up to six guards on every grid station, which cost a lot,” Gudimella adds. “With a fully monitored solution we have been able to reduce the number of guards we need and ensure they’re working where they’re most needed.”
Gudimella concludes, “We now have a robust and reliable system. Gallagher provides a great amount of support to all stakeholders and we are very pleased with the outcome of this project.”
