Biography• New England Energy Solutions was created to
address escalating energy costs• Invested heavily in wood to energy• Currently involved in more than 20 major
wood energy projects• Prime consultant & lead on a 630 connected
load community heat project• Prime consultant on 2 industrial park CHP• Been to Europe to see how it works• Speak and present to many groups and
organizations regarding wood energy

What is district heating?
District heating, also known as central or community heating, is simply the connection of more than one building to a common heating plant or source of heat.
Generally, a heating medium is piped via underground pipe distribution system, then connected to the end user facility.
Could be steam, hot water, or oil.
June 28, 2010
How long has it been around?District heating is not new, in fact the
hot water baths and greenhouses of the ancient Roman Empire were heated in this manner.
One system in France has been in continuous operation since the 14th century.
The Naval Academy in Annapolis began steam district heating service in 1853.
June 28, 2010
How long has it been around?
New York City has used steam district heating since 1882 and is the largest in the world.
Dartmouth College in NH first used wood in 1895.
St. Paul, MN went online in 2005, 25MW cogen & cooling, serves 20,000 customers in a downtown setting.
June 28, 2010
25 MW plant serving 20,000 customers located in the middle of the City

Advantages of district heat
1. Huge energy savings for fuel2. Reduced operational costs, 1 plant3. Less volatility of fossil fuel fluctuations4. Reduces emissions5. Keeps 85% of fuel revenues local

What type of design?• Must decide if thermal only or CHP?• Will there be cooling load?• Will it operate year round or heating
season only?
• Based on the above, thermal lead or electric lead?
• Wood only or dual fuel?• What % will wood produce?

Moving forward
Establish a budget to move concept forward
Select a team with district heat experience
Full engineering and feasibility studies is what is needed but pricey
Perhaps start with a “pre-feasibility” study
June 28, 2010
Getting started
Scope of Workfor a
“pre-feasibility” studyof a community heating project
and possible electrical generation
June 28, 2010
Scope of Work1. Determine scope and scale of project2. Consider inclusion of major institutions and business3. Determine fuel type(s)4. Identify long term, locally sourced, environmentally
sustainable fuel source5. Assessment of appropriate systems6. Maximizing energy efficiency & environmental sustainability7. Cost comparison between biomass & existing fossil fuel
systems8. Consider impact on local HVAC & fuel providers9. Boiler siting & fuel storage & handling10. Identify complementary technologies & fuel, such
as solar, geothermal, methane, wind, or other
June 28, 2010
Scope of Work continued
11. Communicate w/public re: costs & benefits of a local distributed energy system
12. Return on investment time frame w/ alternativeenergy comparisons
13. Opportunities for new businesses: greenhouse, coldstorage, pellet mfg, other
14. Opportunities for summer cooling15. Identify financing opportunities16. Estimated costs associated w/ each system
June 28, 2010
Is it feasible?• Deliver reports for group discussion• Present to community or decision
makers• Final design• Funding• Construction• Start saving $$$$$$$• Energy independence

Wood fuelsThere are differing grades of fuel available depending on
your needs and desired operational outcomes.
Premium quality chips (our best)Mid-grade quality chips (our 2nd best) Low-grade quality chips (our 3rd best)
Bio-mass chips (our 4th best) All of the above grades will work in most high quality boilers, especially gasifiers. The difference will be the heat output and amount of tending to the boiler by the boiler operator; the lower grades may require more tube cleaning and ash disposal. Even with the slight additional costs of human intervention, the lower grades are worth considering as significant heat savings will more than offset the additional man hours.

Thank you….
Burn Maine woodNOT
Foreign oil
and create Maine jobs too!
