Overview
McLean Wind Farm Step-Up Transformer is an operational substation in the United States, operating at 138 kV to support wind energy integration into the grid.
McLean Wind Farm Step-Up Transformer is a substation located in the United States, serving as a critical interface for the McLean Wind Farm to connect renewable energy to the transmission grid. Operating at 138 kV, this facility steps up voltage from the wind turbines for efficient long-distance power transmission, aligning with typical voltage levels for wind farm collection systems in the US. The substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC), ensuring compliance with reliability standards for grid interconnection. As part of a wind energy project, it likely incorporates modern switchgear and protection systems to manage variable power flows and maintain grid stability. Environmentally, the substation supports clean energy generation by enabling the delivery of wind power to consumers, reducing reliance on fossil fuels. Its location in central Illinois contributes to the region's renewable energy portfolio, though specific ecological impacts are minimized through standard siting practices for electrical infrastructure.
Environmental context
The substation is situated in a rural area of central Illinois, where agricultural land dominates the landscape. Its role in connecting wind power helps reduce greenhouse gas emissions by displacing conventional generation. The facility's design likely includes measures to minimize electromagnetic field exposure and prevent oil leaks from transformers, though specific environmental safeguards are standard for modern substations.
Frequently asked questions
The substation is located in the United States, near McLean, Illinois, at coordinates 40.590020, -89.046741.
The substation operates at 138 kV, which is a common voltage for wind farm collection systems in the United States.
A step-up transformer increases the voltage from the wind turbines (typically 34.5 kV) to transmission-level voltage (e.g., 138 kV) for efficient long-distance power delivery to the grid.
The substation must comply with NERC reliability standards for grid interconnection and FERC regulations for transmission-level assets, ensuring safe and reliable operation.
By connecting the McLean Wind Farm to the transmission grid, the substation enables the delivery of clean wind power to consumers, supporting the transition to renewable energy sources.
