Utility proposes agreement with landfill waste to energy project


Idaho Power Company is asking state regulators to approve a 20-year sales agreement with Dynamis Energy LLC’s landfill waste to energy project at the Ada County landfill near Boise. 


At maximum capacity, the project can generate 22 megawatts, according to Eagle-based Dynamis.  If the sales agreement is approved by the Idaho Public Utilities Commission, the project is anticipated to be operating by Feb. 14, 2014. 


The project is a qualifying facility under the provisions of the Public Utility Regulatory Policies Act. PURPA requires that electric utilities offer to buy power produced from qualifying small power producers or cogenerators.  The rate to be paid small-power producers is to be equal to the cost the utility avoids if it would have had to generate the power itself or purchase it from another source. The commission must ensure the avoided-cost rate is reasonable for utility customers because 100 percent of the cost is included in customer rates. 


The agreement states the developer would be paid a 20-year levelized price of $92.53 per megawatt-hour, though the pricing stream varies based on the time of year and the time of day that energy is delivered to Idaho Power. 


The agreement also states that the value of the Renewable Energy Certificates that would be generated over the 20-year contract would be shared equally by the developer and Idaho Power.  


The commission is taking comment on the proposed sales agreement through Feb. 2.  Comments are accepted via e-mail by accessing the commission’s homepage at and clicking on "Comments & Questions About a Case."
