American excellence without sacrificing profitability.

Megrant Corporation was able to re-imagine an energy project destined for overseas manufacturing, creating a new model for large-scale construction nobody expected. By building a 125 acre facility with access to major waterways, hundreds of skilled jobs were created right here, and owners are given unprecedented access and transparency.

Megrant was recently awarded and is in the process of completing a multimillion dollar project to help bring more power to the City of New York. One of the largest power production projects of its kind to address the power generation needs of New York City. Megrant was contracted to manufacture and install a 24 cell GEA Air Cooled Condenser as part of the Astoria II Generating Plant in Astoria, NY. The units which are manufactured in Port of Coeymans NY, will be loaded onto barges and delivered to the job site via New York waterways. This represents an innovation in engineering and construction logistics. Procurement and fabrication of this project began in late 2009, delivery of the assembled units to Astoria began in June 2010, and the installation of the project is expected to be completed by Spring 2011. This project will bring a new 550 MW Combined Cycle Power Generation to Astoria, NY and will service the City of New York. The project was made possible in part by the hard work, and dedication of our staff at Megrant.
