US and Canadian Efficiency Program Budgets, 2007–2011
> Growing and maturing gas programs across U.S.
> Bigger budgets, bigger savings goals
> Low gas prices making efficiency less desirable and cost-effective (e.g. TRC)
66
Expanding Supplies & Low Prices Driving Gas Demand
> Consumer demand growing ─ 2012: All-time high─ Continued upward trend
> Over 25 Tcf market by 2020, above 27 Tcf by 2030
Growth drivers:> Power generation and CHP> Rebounding Industrial Sector> Transportation (high growth rates)
Offsetting reliance on coal and oil
77
Industrial Natural Gas Demand
> Industrial natural gas use rebounding─ Highest level since 2002
─ Positive economic indicator─ Growth to continue with low gas prices, “onshoring”
trends, major investments (nearly $100 billion)
88
Commercial and Industrial CHP Market Trends> C&I CHP markets “status quo” over past decade –despite large
increases in gas use for power generation (missed opportunity)
> Industrial growth could help promote new CHP investments and energy efficiency improvements
> Key issue: resolving long-standing market barriersSource: DOE EIA Electric Power Annual

Ilios High Efficiency Water Heater
> Technology
─ A high efficiency water heater for commercial locations with a gas demand of 4,000 therms/month or more. With a COP of 1.2 to 1.8 and a hot water delivery temperature of 100°F to 160°F this product yields sizable natural gas and operation savings.
> Savings Potential─ 2 to 4 year payback period, depending on
ambient temperature, run time and temp, fuel price, and federal/local incentives .
> ETP Review─ The primary barrier to widespread adoption of
the Ilios product in ideal applications is the high first cost.
─ Recent low natural gas prices have extended the period for return on investment.
─ Maintenance is required every 10,000 to 20,000 runtime hours. Maintenance costs are higher than equivalent electric heat pump products.

Cogenra Solar Combined Heat and Power
>Technology─ Solar cogeneration of electricity and hot
water maximizes the value of energy generated from the sun by producing electricity with standard photovoltaic (PV) technology, and capturing excess heat as hot water up to 100°C
─ The system can offset additional electricity on demand by paring stored hot water with thermally-driven chillers or organic rankine cycle turbines (ORCs)
─ The process of transferring away the heat simultaneously cools the cells, enhancing the collectors’ total efficiency up to 80%.
> Cost / Benefits─ Solar cogeneration 50% more net energy
value compared with photovoltaic per dollar of total installed costs
