The Digital Energy Solutions (DES) business of Larsen & Toubro has secured a mandate to implement energy management systems (EMS) in south India. The business has also expanded its portfolio in the United States.
The Digital Energy Solutions (DES) arm of Larsen & Toubro’s Power Transmission & Distribution (PT&D) business has received the mandate to develop and implement Energy Management Systems in regional and state load dispatch centers in South India.
This order is the latest addition to such digitally based intelligent projects being executed by L&T DES globally, a release by L&T said.
As part of the order in southern India, energy management system and associated software systems will be implemented for 12 set of control rooms. These systems are being implemented for main and backup configurations for the Southern Regional Load Dispatch Centre (SRLDC) and the State Load Dispatch Centers (SLDC) of Andhra Pradesh, Kerala, Puducherry, Tamil Nadu and Telangana. The integration and implementation of these systems will be carried out without causing any downtime for the existing system.
L&T DES will implement this upgradation of control rooms with power system applications supplied by the world’s leading OEM to monitor and control the energy flow in electricity transmission network in real time to ensure reliable and secure grid operations. The upgrade work will leverage L&T-Spark-CRIMTM (Control Room Integration Middleware) Platform to integrate substation data.
Through another recent mandate, L&T DES team will implement upgradation of power and transmission control room in the western United States, with one of the most complex configurations involving more than 15 EMS hosts, deploying advanced applications to monitor and control the energy flow in real-time. The scope includes design and implementation of power and transmission network operation situational awareness to assist operators and analysts to improve grid reliability.
L&T is already executing a slew of advanced grid modernization and digitalization orders in India, including the upgradation work in National and Regional Transmission Asset Management Centers consisting of 13 control rooms nation-wide integrating 270 EHV transmission substations.
On the distribution grid management side, L&T DES is implementing advanced distribution management systems in Mumbai and Vadodara.
Mandates in the US
In Puerto Rico, United States, L&T DES team has been working on an interconnection simulation study and substation control engineering assignment involving eight grid-interactive renewable hybrid substations consisting of solar and storage. Upon the successful completion of engineering design phase for the first substation, L&T DES team in USA has been awarded to implement L&T-Spark-HECSTM (Hybrid Energy Management and Control System) thus providing end to end solution delivery from design to completion. The offered solution will be one of the first fully integrated implementations combining Solar, Energy Storage and Substation supervisory monitoring and control, from a single platform with full functional Historian and Hyper Local Energy Forecasting duly integrated with weather monitoring system.
L&T DES business in USA is all set to provide turnkey solution for 300-MW Solar “Balancing Authority” services in western United States. Balancing Authority (BA) services enable renewable plant integration while meeting NERC (North Electric Reliability Council) criteria administered by regional reliability council for reliable operation of renewable asset and grid. These services will facilitate multiple monetary value streams by allowing energy transactions within and beyond the local utility jurisdiction, availing most optimum combination of trades and transactions while meeting NERC and WECC (Westen Electric Coordination Council) reliability compliance. The project will be delivered by the facility called HENOC (Hybrid Energy Network Operation Center) in Fairfield, California, USA. The facilities and personnel involved in the project have been certified by NERC.
