Power+ Generator

Next Generation Heat Recovery Solution

Using an organic Rankine cycle (ORC) along with proprietary technologies, the Power+ Generator converts sources of  geothermal heat and waste heat into electricity – with no additional emissions or fuel consumption.

ElectraTherm’s heat recovery systems utilize low temperature heat sources previously deemed insufficient for power generation to do just that – generate power. With units available in multiple sizes with a larger (300 kW) unit in development, ElectraTherm’s systems are ideal for small- and mid-scale applications.

The Power+ Generator effectively utilizes available thermal energy (excess heat) to produce clean electricity. In addition to this, the heat recovery system can (1) serve as a combined heat and power (CHP) system, (2) act as a radiator alternative with the ability to substantially reduce or eliminate the cooling load, and (3) provide a profitable means of reducing natural gas flaring.

Higher temperature heat sources – such as thermal oils and exhaust gases – can be utilized with the deployment of an additional heat exchanger.

Our heat recovery solutions are available as either standalone units or fully-packaged systems – depending on the existing infrastructure. Need help determining which ORC system is right for you? Fill out our Project Evaluation Form or Contact Us.


The integration of a semi-hermetic, twin-screw expander gives ElectraTherm’s ORC systems an advantage over competitive technologies and opens market opportunities where waste heat recovery has previously been either impossible or unpractical.

The custom built expander, along with proprietary technologies and lower operating speeds, provides a more cost-efficient, robust design that greatly enhances reliability and functionality. ElectraTherm’s ORC process utilizes much more variable heat sources made possible by the expanders’ ability to handle “wet” dual-phase flow, leading to greater turndown ratios which allow for continuous power generation when dealing with inconsistent thermal conditions.

DOD Increases Fuel Efficiency By 10%

In collaboration with the U.S. Department of Defense, ElectraTherm commissioned a fully packaged Power+ Generator integrated with a 1.1 MW engine. The ORC system was able to increase fuel efficiency by 10% while completely offsetting the cooling load, serving as a radiator alternative.


24/7 Industrial Waste Heat

A Virginian pharmaceutical facility decided to take advantage of the waste heat from their 500 kW air compression system by installing a single Power+ Generator to utilize their existing resource. The unit experiences 24/7 operation and generates 45 kW gross, or 394 MWh annually.


Geothermal Power From Co-Produced Fluids

In collaboration with the Department of Energy and Jipangu International, ElectraTherm commissioned a containerized unit at a mine in Nevada to utilize the thermal energy from co-produced fluids to generate clean electricity. This application demonstrates the system's ability to reliably operate with little hand-on interaction through ElectraTherm's remote monitoring and operation controls. The heat source provides hot water at 110°C with a flow rate of 9.5 l/s to generate 65 kW gross.


Remote Power Generation in Alaska

Three Power+ Generators (4400 series) were installed at a power station in Dutch Harbor, Alaska with the goal of improving energy efficiency. The units provide 75 kW (net) to the site as well as reduce the cooling load enough to replace one of the existing radiators. The Alaska Energy Authority estimates $250,000 in annual energy savings. Additionally, by serving as a radiator alternative, electrical consumption is reduced by 8,000 kW monthly - saving 6,000 gallons of fuel annually.


Ten Power+ Generator Scalable System

ElectraTherm commissioned ten Power+ Generators (4400 series) on a district heating system powered by two Rolls Royce gas turbines in Levice, Slovakia. ElectraTherm utilizes the exhaust gas waste heat to provide 500 kWe of clean electricity which is sold back to the utility for profit.


Geothermal Heat Recovery in Japan

Utilizing geothermal steam from a district heating system in Beppu, Japan - ElectraTherm's Power+ Generator provides up to 60 kW. For Japan, this electrical output is extremely profitable - fetching up to $0.33 per kilowatt. This site provides hot water to the unit at 110ºC with a flow rate of 12 l/s.

Good For The Environment


By upcycling waste heat into usable power you generate 4.8 GW of clean electricity and offset the equivalent of 3,400 metric tons of carbon dioxide annually.

Your annual pollution offset is equal to taking 740 cars off the road, or reducing gasoline consumption by 385,000 gallons.

Your pollution offset is equivalent to the carbon sequestered by a 4,200 acre forest, or 160,000 mature trees.

The clean power generated is equivalent to the emission offset of 620 homes’ electricity use annually, or 140,000 cylinders of propane used for backyard barbeques.

Good For Business

Simple. Reliable. Profitable. Sustainable.


The simple and flexible nature of our ORC solutions allows them to be adjusted to fit the needs of any application. A robust, modular, and scalable design allows the system to be easily integrated into existing processes while allowing for future adjustments. Able to successfully operate at partial loads with varying conditions also means that the system will produce electricity even when your processes are not at capacity.


Every ElectraTherm product goes through a rigorous testing process at our world-class R&D test cell to ensure absolute reliability. Our technicians and dedicated global partners offer full support for any issues you may encounter throughout the product lifecycle.


Our systems use existing heat as fuel, keeping operating costs minimal. ElectraTherm converts this heat into clean electricity, ready immediately. This increases energy efficiency – up to 10% – while substantially reducing energy consumption, primarily the cooling load. ElectraTherm’s ORC solutions may also qualify for local sustainability incentives as well as enabling micro-grid functionality in remote regions. With an impressive 20-year design life and a payback period of 3-5 years, the economics amount to an attractive return on investment.


Over 50% of energy used in power generation and industrial processes is lost as heat – making this heat an enormous source of renewable energy. Increasing energy efficiency by upcycling this waste heat into emission-free electricity is the single easiest way to mitigate emissions and achieve sustainability goals.
