Cogeneration

COMBINED HEAT AND POWER (CHP)

At XLS Energy, we believe the future of electric supply trends toward moving away from large central power plants, and many miles of transmission lines, to smaller on-site distributed generation facilities.  Smaller generating facilities, located close to the demand they serve, will provide more efficient, less costly and highly reliable power.

Currently, XLS Energy’s focus is on development of CHP projects that are smaller, distributed type installations. The Federal Government has announced a target of installing 40,000 MW of new CHP plants by 2020, adding to the over 83,000 MW currently operating in the U.S.

To be a good candidate for a CHP installation, your facility needs to operate for a minimum of 5,000 hours per year and have significant, coinciding power and thermal energy loads.  XLS Energy can complete a feasibility study for your facility and determine what size CHP plant makes sense for you, as well as determine the level of savings CHP will provide for your facility.

XLS Energy is your one-stop development shop to help you realize tremendous savings on your energy costs, while also increasing the reliability of your power supply and reducing your carbon footprint.

HOW DOES COGENERATION (CHP) WORK?

The fundamental advantage of CHP is in the efficiency of using one fuel source for the production of electricity, and the steam for heating and cooling from waste heat.  This “cogeneration” can be more than twice the efficiency of the typical arrangement where one gets power from the grid and also makes steam using boilers on site.

Free “waste” heat is recovered from the cogeneration system’s engine oil, jacket, and exhaust heat.  Captured heat is then used to offset fuel that would otherwise have to be burned in the site’s water heaters and boilers.  This allows the site’s boilers to not have to work as hard.  So the site’s gas bill (e.g., for space heating, domestic hot water, process hot water, pool heating, etc.) goes down, too.

Because the heat used to make steam used for heating, hot water, chilled water or cooling is a “waste product” of the power generation, the overall efficiency of a CHP plant is up to 85%, compared to 40% “off the grid”.  This also means that the overall fuel consumption for your energy needs is reduced by 35%, and the total emissions by 50%. CHP is a step-up on all levels!

 

INDUSTRIAL AND COMMERCIAL FACILITIES

XLS Energy cogeneration and cooling CHP products are a proven way for commercial and industrial facilities to reduce their operating costs and carbon footprints significantly, and maximize overall efficiency.  Commercial and industrial facilities are often large with around-the-clock operations, steady thermal and electric requirements, and central plants.  This makes them ideal candidates for CHP.

Best industrial applications include pharmaceutical, electronics manufacturing, metal finishing, plastics, bottling, industrial office parks, warehouses, and food processing facilities.  Best commercial applications include hotels, data centers, shopping centers, and office buildings with high occupancy and consistent requirements for heating and/or cooling.

The “Microgrid” feature of XLS Energy’s technology is particularly valued in commercial and industrial facilities, because it can be easily configured to provide convenience power during an outage, keeping important services operating until the utility grid is restored.

Operating savings to a commercial or industrial facility can be over 50%, year after year.  XLS Energy CHP systems can help attentive industrial and commercial facility managers squeeze the most value out of limited budgets, in a very competitive world.  We would be happy to provide you a detailed free economic analysis, to help you estimate the savings at your particular facility.

MULTI-FAMILY RESIDENTIAL

XLS Energy’s cogeneration and cooling CHP products are a proven way for larger multi-unit residential facilities to reduce their operating costs and carbon footprints significantly, and maximize overall efficiency.

Large residential facilities represent an excellent match for CHP systems, due to their steady electric and thermal loads. Best applications include large apartment buildings, condominiums, dormitories, retirement homes, and co-ops. Those with centralized heating systems and centralized electric metering are especially good candidates.

Efficient XLS Energy CHP systems can help a residential building reduce its Greenhouse Gas emissions (CO2 output, or “carbon footprint”) by as much as 50%.  XLS Energy CHP systems are a good way for a residential building to “go green”, but in a practical, sensible way.  They reduce global warming emissions, while achieving decent paybacks on their own and do not rely extensively on massive government incentives and tax benefits, like some other “green” measures do. XLS Energy CHP systems are an efficient and responsible investment of property owner and taxpayer dollars.

Operating savings to a residential facility can be over 50%, year after year.  XLS Energy CHP systems can help attentive property managers, residents, and owners squeeze the most value out of limited budgets.  We would be happy to provide you a detailed free economic analysis, to help you estimate the savings at your particular facility.

HOSPITAL AND MEDICAL FACILITIES

XLS Energy CHP cogeneration and cooling CHP products are a proven way for hospitals and nursing homes to reduce their operating costs and carbon footprints significantly, and maximize overall efficiency.

Hospitals and nursing homes are often large facilities with around-the-clock operations, large steady thermal and electric requirements, and central plants. This makes them ideal candidates for CHP systems. Best applications include small and large hospitals, medical office buildings, and nursing homes serving at least 100 residents.

XLS Energy CHP cogeneration systems can generate electricity that reduces a hospital’s or nursing home’s electrical bill significantly. At the same time, free waste heat can be recovered from the cogeneration system and used to offset fuel that would otherwise have to be burned in the facility’s boilers or water heaters.  So in addition to savings on the electricity bill, the gas bill for space heating and domestic hot water is also reduced. Alternatively, the free waste heat can even be used to drive an absorption chiller, a device which generates cooling from a heat source, thus relieving the hospital’s or nursing home’s other chillers from having to do as much of the air conditioning.
