Section 170 IAC 17.1-3-5 - Useful thermal energy conversion to clean energy creditsAuthority: IC 8-1-1-3; IC 8-1-37
Affected: IC 8-1-37
Sec. 5.
(a) For clean energy resources that provide thermal energy, one (1) clean energy credit shall be earned for every three million four hundred twelve thousand (3,412,000) British thermal units (Btus) of useful thermal energy produced.(b) The useful thermal energy produced by a clean energy resource shall be the thermal energy used for the following: (c) The useful thermal energy may be: (1) measured directly by meter; or(2) determined: (A) by the default equation in this section; or(B) through an alternative equation approved by the commission through its thirty-day administrative filing process in 170 IAC 1-6.(d) The following default equation may be used to determine the quantity of clean energy credits generated: Click here to view Image
Where: CECs Generated = Quantity of CECs generated (MWh)
Q = Quantity of steam or hot water delivery (lbs)
[DELTA] H= Change in enthalpy from point of delivery to end of thermal energy use (Btu/lb) Default for steam = 830 Btu/lb
Default for hot water = 300 Btu/lb
eL = Energy loss from point of delivery to point of use (fraction)
Default = 0.15
