The Linden Cogeneration Plant New Jersey, represents a key example of how combined heat and power (CHP) systems can enhance energy efficiency and reliability in the United States. As global energy demands grow and environmental concerns become more pressing, cogeneration facilities like Linden play an increasingly vital role in modern power infrastructure. Unlike conventional power plants that waste a significant portion of energy as heat, cogeneration plants utilize that thermal energy for industrial or district heating purposes, drastically improving overall efficiency.
This article provides a comprehensive overview of the Linden Cogeneration Plant, focusing on its location, technical specifications, operations, environmental benefits, and its strategic role in both local and regional energy markets.
Location and Background
The Linden Cogeneration Plant is situated in the city of Linden, Union County, New Jersey—strategically positioned within one of the most industrialized corridors of the northeastern United States. Its location offers close proximity to key infrastructure such as the New Jersey Turnpike, Port of New York and New Jersey, and several major oil refineries, including the adjacent Bayway Refinery operated by Phillips 66.
Commissioned in the early 1990s, the plant was initially developed to provide reliable electricity and process steam to meet the energy demands of local industries. Over the years, ownership and operational structure have evolved, often involving partnerships between private energy firms and industrial stakeholders. The plant continues to serve as a cornerstone of regional energy security and industrial productivity.
Technical Specifications
The Linden Cogeneration Plant boasts a total generation capacity of approximately 900 megawatts (MW), making it one of the largest combined heat and power (CHP) facilities on the East Coast of the United States. The plant operates primarily on natural gas as its main fuel source, with ultra-low sulfur diesel (ULSD) available as a backup for operational flexibility and reliability.
The facility comprises six gas turbines and three steam turbines, arranged in a multi-shaft configuration. Each gas turbine is coupled with a Heat Recovery Steam Generator (HRSG), allowing the plant to recover and reuse waste heat to produce high-pressure steam. This steam is then used to generate additional electricity via steam turbines and to supply process steam to nearby industrial users, such as the Bayway Refinery.
Key features include:
- Combined-cycle design for high thermal efficiency (up to ~80%)
- Dual-fuel capability to ensure reliability under varying fuel supply conditions
- Advanced emission control systems, including low-NOx burners and Selective Catalytic Reduction (SCR) units
- Black start capability, enabling grid support during outages
These specifications enable the plant to operate with a high capacity factor, rapid start-up capability, and minimal environmental impact compared to conventional fossil fuel-based generation.

Operational Overview
The Linden Cogeneration Plant operates as a combined heat and power (CHP) facility, delivering both electricity and steam with exceptional efficiency. The plant is connected to the PJM Interconnection, one of the largest regional transmission organizations in the United States, enabling it to supply power directly to the grid and support regional energy demand.
A key aspect of its operation is the steam delivery system. The high-pressure steam produced from recovered heat is piped to nearby industrial customers, most notably the Bayway Refinery, where it is used for various refining processes. This seamless integration between electricity and thermal energy production significantly reduces fuel consumption and environmental impact compared to separate systems.
Operational highlights include:
- Flexible dispatch capability to meet varying grid demand
- Rapid start-up and load-following features
- Real-time monitoring and automation for optimized performance
- Scheduled maintenance cycles to ensure high availability and reliability
Thanks to its cogeneration design and strategic partnerships, the Linden plant achieves a capacity factor above national averages, maintains low emissions, and plays a critical role in grid stability during peak demand or unexpected outages.
