The energy and healthcare industries share a mutual woe. Both are experiencing meteoric price increases.

The Alliance to Save Energy projects a household’s energy costs will be about $6,300 this year, representing about 13% of median pre-tax earnings. Meanwhile, the National Coalition on Health Care reports that medical costs rose 6.9%— two times the rate of inflation last year with total spending of $2.3 trillion or $7,600 per person. http://www.nchc.org/facts/cost.shtml

Fortunately, the U.S. Department of Energy has launched a program that brings energy efficiency to hospitals to drive down energy costs and reduce some of the financial pressure on the healthcare industry. http://www1.eere.energy.gov/buildings/energysmarthospitals/

The program is important because hospitals are significant energy consumers. A hospital’s energy intensity is 2.5 times that of a commercial building. U.S. hospitals spend more than $5 billion annually on energy, which is 1-3% of their budgets and equivalent to at least 15% of profits.

The program’s goal is to improve efficiency 20% in existing buildings and 30% in new construction. Cost savings are expected to be large — every $1 a non-profit hospital saves on energy is equivalent to generating $20 in new revenue, according to the DOE.

Hospitals are particularly good candidates for combined heat & power, which is 70-95% more efficient than conventional power production. CHP, as it is known, achieves this efficiency because it uses the heat produced in the generation process, rather than wasting it, as large grid-connected power plants do. Thus, it is able to use less fuel to electrify, heat and cool a building. http://files.harc.edu/Sites/GulfCoastCHP/Presentations/CHPForHospitals.pdf

CHP also offers hospitals back-up power if the electric grid goes down. During Hurricane Katrina, when almost everything was out of service, the 642-bed Baptist Medical Center in Jackson, Mississippi continued to care for patients without disruption because of its 3.2 MW CHP plant.

The DOE offers a free screening for hospitals so that they can see if they are good candidates for CHP http://www.bchp.org/prof-assessment.html#form

Pairing energy efficiency with other societal needs, such as bringing down healthcare costs, makes for good public policy. It offers the proverbial killing of two birds with one stone, or in this case with one coin reducing a double-burden on the average American’s pocketbook.

Combined heat and power is a form of alternative energy that has been available for many decades. Yet it’s remained below the radar screen in policy discussion about our energy future.

However, it appears to be gaining new stature as lawmakers and regulators seek ways to make energy use more efficient.

Also called cogeneration, the technology creates both electricity and heat in one unit. Most power plants throw away two-thirds of the energy consumed in production. But CHP plants use the excess energy to heat, cool or humidify the building. As a result CHP reclaims one-third of the energy that would otherwise be lost.

In addition, CHP plants are usually built very close the factory, hospital, college or office building they serve. So electricity is not lost as it travels long distances over transmission lines, as is often the case with large, central power plants that serve many consumers and businesses.

Taking notice of CHP’s virtues, some states have created portfolio standards that encourage its development. The standards require that utilities use a certain amount of alternative energy to meet efficient or clean energy targets. This approach has been highly successful over the last several years in spurring development of wind, solar and other green energy sources in the US.

Now eight states allow part of the requirement to be met through installation of CHP. In Connecticut, for example, a factory, school other large energy user can install CHP to meet its heat and power needs and receive a kind of tradable credit for doing so. The energy user then can sell the credit to a utility that needs to meet state requirements.

In addition to Connecticut, the eight states are Colorado, Hawaii, Nevada, North Carolina, North Dakota, Pennsylvania, and Washington. These states should serve as interesting testing ground to see if portfolio standards accelerate use of CHP as they have wind and solar energy.  We encourage those interested in CHP to check out the Environmental Protection Agency’s CHP partnership, an agency that is playing a strong role in encouraging use of the resource.
