Are you interested in lowering your healthcare facility’s energy costs while substantially improving its energy efficiency and simultaneously adding additional back-up power?  

Cogeneration offers the opportunity to generate on-site (behind-the-meter) electricity, while capturing heat as a source of energy. Also known as Combined Heat and Power (CHP), the cogeneration technology generates electricity and, in addition, uses normally wasted heat produced by a power plant to supply facility thermal loads (heating and cooling).  

The benefits of CHP are many and important.  It can:

  • Generate a significant part of your electrical power needs
  • Reduce your exposure to the Global Adjustment, ie, lower operating costs
  • Increase your on-site power generation, improving reliability and self sufficiency
  • Hedge your fuel risk exposure
  • Increase your back-up capacity and operational ability during utility outages
  • Modernize your facility to align with current CSA code intents
  • Decrease operating costs
  • Potentially avoid costs for boiler replacements or diesel generator replacements

There are several key drivers for adopting CHP technology:

  • Decreasing reliability of the electrical grid infrastructure
    The grid is aging and needs refurbishment and, hence, is increasingly less reliable.
  • Severe climate events resulting in utility outages
    These include wind, ice storms, hurricanes, flooding, tornados, and wild fires. It is clearly documented that outages are on the increase, based on more frequent and more severe climate effects.
  • The need to improve resilience for older facilities
    Although CSA standards are not retroactive, aging facilities cannot carry on operations to the degree specified in new standards.
  • Emergency power
    Code changes require continued operations of vital departments and more departments are now classified ‘vital’. Also, renovations drive electrical changes; for example, air handlers that used to be on ‘normal’ power now require emergency power because vital departments are served by the unit. 

CHP is an adjunct power source for conditional loads and non-essential loads, as well as air conditioning. The financial advantages of CHP are due to several factors:

  • Electricity prices are certain to continue rising. 
  • There is increased supply of domestic natural gas and prices are forecast to remain stable. 
  • Provinces have funding programs for CHP, such as Ontario’s CHPSOP program and the PSUI (Process & Systems Upgrade Incentive) program. Ontario recently recognized CHP as ‘energy savings’ from the grid, and will fund up to 40% of the capital cost for behind-the-meter CHP. 

HH Angus and Associates has been designing cogeneration plants for over two decades. We were the first in Canada with Combined Heat and emergency Power (CHeP), a project which garnered an award from the Consulting Engineers of Ontario.  Some examples of our CHP healthcare portfolio include Lakeridge Health Oshawa, North Bay Regional Health Centre, Thunder Bay Health Sciences Centre and Villa Colombo in Vaughan, ON. We have completed numerous feasibility and detailed engineering studies, comparing OPEX and CAPEX, and determining if the technology makes sense for a given facility.
