GE to modernise Rajasthan’s transmission grid

21 March 2019

GE Renewable Energy’s Grid Solutions business has been awarded a technology-driven grid modernisation project, the first-of-its-kind in India, by Rajasthan Rajya Vidyut Prasaran Nigam  (RRVPL) as part of the utility’s plan to implement grid initiatives and augmenting renewable energy in the state. The project will be executed by GE T&D India Ltd.

Smart Transmission Network and Asset Management System (STNAMS), RRVPL’s state-of-the-art power transmission roadmap, was designed to integrate large-scale renewable energy and support managing existing and future power structure. A first by a state utility in India, the project investment totalling USD 21 million (Rs 150 crore) demonstrates the need for efficient, stable and secured operation of the grid.

The total installed power capacity of Rajasthan is around 21.6 GW, out of which 34% comes from renewable sources. The state plans to further increase solar and wind generation capacity to 14.3 GW by 2022. To support this focus on renewable energy, the state requires remote monitoring and grid stability.

GE’s Advanced Energy Management System (AEMS) will serve as a foundation for RRVPL’s roadmap and enable the utility to alter production levels based on demand. The software will provide real-time data acquisition and a decision support system that will help in visualisation and situational awareness of the transmission grid. The data displayed at RRVPL’s Smart Grid Command and Control Centre will help in monitoring health of critical assets. The RRVPNL-STNAMS project will also include software features of National Transmission Asset Management Centre (NTAMC) & Unified Real Time Dynamic State Measurement (URTDSM), both implemented by GE for Power Grid Corporation of India Limited and will strengthen monitoring of the entire grid system of Rajasthan.

Sunil Wadhwa, Managing Director, GE T&D India Limited and Leader of GE¹s Grid Solutions business in South Asia said, “The variable nature of renewable assets requires a fundamentally different approach to balance the supply and demand. Therefore, the grid of the future will require smarter, faster and more interoperable solutions to ensure resiliency, efficiency and security. India¹s renewable energy targets urgently require the state utilities to be able to make informed and accurate decisions for which advanced Smart Grid management systems will play a key role. “

The RRVPNL-STNAMS project will have 535 substations remotely connected to the three control centres:  a main control centre in Jaipur, a back-up control centre in Jodhpur and an additional regional centre in Ajmer ­ which will help in remote visualisation of power flow and asset health. GE’s Advanced EMS will make available Wide Area Monitoring Systems to avoid the instability in the transmission system operation, identify major areas contributing to transmission losses and undertake remedial action to reduce transmission losses. Additionally, GE’s grid software solution will also provide remote operations and control of the substations and network, enabling existing technical workforce to focus on asset maintenance/management, grid monitoring and efficiency improvement-related work.
