Woolwich Bio-En adds ORC to anaerobic digester power plant

Feb. 26, 2019 - Clean Energy Technologies (CETY) has installed a Clean Cycle II Organic Rankine Cycle (ORC) unit at Woolwich Bio-En, Inc. in Elmira, Ont.

Woolwich is an anaerobic digester power plant that utilizes two Jenbacher JGC420 generators to produce 1426 kW of electricity each, and, as a by-product, these generators give off waste heat. CETY’s Clean Cycle II ORC utilizes the plants wasted heat lost to the atmosphere through the exhaust stream to essentially produce free electricity with no additional fuel required, resulting in an expected annual electrical savings of 769,149 kWh.

CETY’s ORC technology is considered one of the most advanced in its class and being maintenance-free allows the cost of operation to be very low.

In addition to capturing additional power generation for Woolwich, the ORC is offsetting natural gas fired turbines that have an overall efficiency less than 40 per cent.

This successful installation will also be used as a platform and proof-of-concept demonstration for similar opportunities in Canada and indicates the great potential for this technology throughout Canada and around the world.


CETY’s Organic Rankine Cycle Generator Clean Cycle IITM is ideal for capturing heat from a large range of sources to produce substantial amounts of electricity. The result will be essentially “free” power as all the heat that is currently being ejected to the atmosphere is utilized by Clean Cycle IITM generator.

Kam Mahdi, CEO of CETY said, “We are extremely proud that we have helped Woolwich to reduce their overall energy consumption and increase their return on investment. This successful installation of our biomass and CHP (combined heat to power) application will serve as a showcase to this large industry that is searching for energy savings solutions. We look forward to introducing our proprietary heat-to-energy solutions to large numbers of biomass operations, high rise buildings, large reciprocating engines, and operations where large amounts of heat are lost, as these are excellent customers that can benefit substantially from our systems.”

It’s been reported that 20 to 50 per cent of industrial energy input is lost as waste heat in the form of hot exhaust gases, cooling water, and heat lost from hot equipment surfaces and heated products.

The U.S. Department of Energy claims CHP heat recovery systems for under 500kW represent 220,000 systems. CETY’s proprietary heat recovery systems are 140kW and are right in the sweet spot where user’s needs are the highest. CETY is also excited about entering the large high rise market with its first installation slated for the 1540 Broadway high rise building in Manhattan.
