LA시 위생국의 히페리온(Hyperion) 정수 플랜트를 가동하기 위해 생산되는 스팀·전기의 100%를 공급하게 될 25㎿ 규모의 바이오가스 연료 열병합 발전소가 시공에 들어갔다. 이번 열병합 발전소는 히페리온의 하수처리공정을 통해 걸러진 메탄을 연료자원으로 이용해 연간 1억7천300만㎾h 이상의 전력을 생산하고 시간당 최대 7만 파운드의 스팀을 공급할 것으로 기대된다.

LA 위생국은 경쟁입찰 끝에 엑셀론 제너레이션(Exelon Generation)의 자회사인 콘스텔레이션(Constellation)을 프로젝트 개발자로 선정했다.

 

 

 

Construction has begun on a 25-megawatt (net) biogas-fueled cogeneration plant, which will supply 100 percent of the steam and electricity produced to power LA Sanitation's Hyperion Water Reclamation Plant.

 

The cogeneration plant is expected to generate more than 173 million kilowatt-hours of electricity per year and supply up to 70,000 pounds per hour of steam, using the methane captured through Hyperion's sewage treatment process as its fuel source.

 

LA Sanitation selected Constellation, a subsidiary of Exelon Generation, as the project developer after a competitive bidding process. Constellation will develop, construct and operate the cogeneration facility for 20 years, with an option to extend the agreement for two additional five-year terms.

 

By using biogas fuel to generate electricity instead of brown power sources, the Hyperion cogeneration plant is expected to avoid the release of approximately 100,000 metric tons of carbon dioxide each year, or the equivalent emissions from over 21,000 passenger vehicles annually, according to an estimate from LA Sanitation. In the event of an electric grid outage, the cogeneration plant has the ability to maintain operations at the wastewater treatment site.

 

Commercial operation of the Hyperion cogeneration plant is scheduled for the end of 2016.
