Moxa to Upgrade Thailand’s PEA into Sustainable Power Hub

Italthai Engineering has enlisted Moxa’s network expertise to improve the flexibility and efficiency of the power grid by optimizing the management of the overall network.

Moxa has partnered with Thailand’s Provincial Electricity Authority (PEA) and Italthai Engineering to transform Pattaya into a smart city by upgrading its electrical infrastructure to a smart grid.

Moxa Thailand’s PEAThe digital upgrade also enables PEA to spearhead the Thai government’s Energy 4.0 initiative, driving the energy transition progress that is contributing to Thailand’s economic success and its competitiveness among ASEAN nations.

“In implementing and maintaining a digital substation communication system, we need an expert we know we can trust,” said Pongsakorn Yuthagovit, Assistant Governor for PEA. “Moxa’s expertise in critical network communication helps us set the cornerstone for optimizing the flexibility and efficiency of the smart grid through automated communication, monitoring, and management of the overall power network.”

“Moxa is honored to support PEA’s transformation by providing our expertise in substation automation for Pattaya,” said Andy Sun, director of the Vertical Market Business Unit at Moxa. “As an OT expert in the field, our 35 years of experience in industrial networking and communications has helped us hasten PEA’s seamless transition from a manual to a digital way of working, and in turn move Thailand towards a cleaner, smarter economy.”

The key to the transformation is the digital upgrade of Pattaya’s substations to improve power delivery and minimize unstable voltage supplies during power outages. Pattaya is now better equipped to support its prosperous tourism industry and expand its advanced manufacturing sector in Thailand’s Eastern Economic Corridor, the country’s flagship economic zone.

To attain the goal of Energy 4.0 and making Thailand a power hub for ASEAN by the year 2036, PEA, serving 99% of Thailand’s population, is collaborating with Italthai Engineering for various pilot projects, including a project that improves the flexibility of the smart grid for permitting greater usage of highly variable renewable energy sources.

Italthai Engineering has enlisted Moxa’s network expertise to improve the flexibility and efficiency of the power grid by optimizing the management of the overall network.

Italthai Engineering recognizes Moxa as an excellent partner with expertise in critical network communication in IEC 68150-based substation automation systems.

The new design provides outstanding PRP/HSR redundancy to ensure that PEA’s substation systems enjoy reliable communication with zero packet loss and zero-time recovery.

Not only has the digital transformation made PEA’s power network in the region more flexible and stable, but the network is also now compliant with IEC 61850, the international standard of communication protocols for intelligent electronic devices at electrical substations.

The upgrade uses Moxa’s IEC 61850 PRP/HSR redundant network to enable substations to operate automatically and achieve real-time communication.
