Energy / Renewables

Often with our affiliate companies, Cashman is involved in various areas of utility and energy-related design and construction, including renewables, wind energy farms, liquefied natural gas (LNG) infrastructure / storage, and pipeline / energy infrastructure construction support. Cashman’s in-house capabilities and equipment portfolio provide Owners a single contractor capable of building—and even operating—a wide variety of large-scale infrastructure related to energy / renewables production and storage.

From commercial-scale renewable energy projects to oil and gas infrastructure projects throughout the Northeast and beyond, Cashman has diversified its abilities, added expertise and equipment, strengthened core competencies, and maintained its focus on safety and quality. Recent energy / renewables projects include an active development pipeline of wind projects in the Northeast along with management of three operating wind projects; proposed LNG gas storage construction and operation in Maine; marine construction support and tie-in for a gas pipeline crossing the Hudson River in New York City; and construction support for a new lateral gas pipeline and new metering / regulating station for a planned power station facility in Massachusetts.

Cashman’s vision for the future of energy and power sources led the firm to start Patriot Renewables — a wind farm development company with multiple operating projects throughout the Northeast. We also support affiliate firm Preload Cryogenics, a leading prestressed concrete tank design and construction firm for storage of LNG and other cryogenic liquids such as liquefied oxygen (LOX), liquefied propane gas (LPG), and other liquids.

ENERGY / RENEWABLES: Patriot Renewables, LLC

Through subsidiary Patriot Renewables, LLC, Cashman developed and currently owns and operates the 4.5-megawatt (MW) Beaver Ridge wind farm in Freedom, ME; the 20-MW Spruce Mountain Wind farm in Woodstock, ME; and the 34.5-MW Saddleback Ridge Wind operation in Carthage, ME. Patriot Renewables has one wind farm under construction at this time: the 23-MW Canton Mountain Wind farm in Canton, ME. Additionally, the firm is developing the 20-MW Timber Winds operation in Dixfield, ME. Collectively, these projects have the potential to generate more than 80 MW of clean electricity—enough energy to power more than 30,000 Maine homes. Of equal importance, Patriot’s wind projects also helped the state demonstrate its capability to execute on its renewable energy initiatives—an important step in achieving energy stability and independence for consumers.

Focused on providing the cleanest and most efficient energy solutions, our experienced team at affiliate Patriot Renewables continuously seeks to provide reliable power to communities throughout the Northeast. Energy generated by our wind farms is currently powering thousands of homes with no adverse effects on the environment.

ENERGY / POWER: Preload Cryogenics

Through its affiliation with Preload Cryogenics, Cashman has diversified its businesses to include physical energy storage and delivery capabilities. With a creative and innovative approach to natural gas energy / power infrastructure projects, Preload Cryogenics is poised to greatly enhance the economic models associated with development of LNG infrastructure (liquefaction, storage and/or vaporization) as a means to stabilize LNG and natural gas pricing for providers and consumers.

Preload’s precast, concrete cryogenic storage tanks have been operating reliably around the world for more than 50 years. These tanks perform as well as conventional tanks and offer a unique cost- and schedule-effective alternative. Precast concrete tanks provide single-, double- and full-containment storage (as well as membrane storage) for refrigerated and cryogenic liquids, such as LNG, liquid oxygen, liquefied petroleum gas, ethylene, ammonia, etc., for a wide range of storage volumes — 2,000 to 300,000 cubic meters.
