Combined Heat & Power (CHP) System

NextGrid™Generate 100% of your heating and electricity needs on demand and save money!

Local generation has a higher efficiency as it lacks the 8-10 % energy losses when transporting electricity over long distances and the 10-15 % energy losses on long distance heat transfer due to the difference between the hot energy carrier (water) and the colder external environment. The most common systems use some form of methane as their energy source and emit carbon dioxide.

Combined heat and power (CHP) is the simultaneous production of electricity and heat but with the recovery and utilization of the heat. It is also known as “cogeneration”.

In most applications today heat and power are generated separately resulting in high fuel consumption and higher greenhouse gas (GHG) emissions. Cogeneration is a highly efficient form of energy conversion and it can achieve energy (fuel and electricity) savings of 40% or more when compared to the separate purchase of electricity from a local electrical utility and using a natural gas boiler for onsite heating.

A Revolution in Energy Production

Combined heat and power plants are typically installed close to the end user which reduces electricity transportation and distribution losses. (This also improves the overall performance of the electricity transmission and distribution network.)

Combined heat and power plants also provide customers with an additional layer of security by working independent of the electricity grid. This is particularly important for companies and institutions that rely on electricity for critical operations.

NextGrid’s Combined Heat & Power systems are a major technology breakthrough in the combined heat and power industry

NextGrid CHP systems deliver a one-two punch by utilizing patented technology found only in a NextGrid CHP system. Harmonic Resonance Combustion (HRC) technology delivers the highest combustion performance and lowest cost of any CHP technology on the market today, bar none.

Harmonic Resonance Combustion ensures that the majority of the fuel (up to 95%) is converted into useable energy (Heat). HRC is also the reason that NextGrid carbon emissions are vastly lower than all other CHP technology available today. In fact our NOx emission range from an industry leading 0-3 PPM. (Compared with 30-50 PPM for internal combustion engines (ICE) and gas combustion turbines (CGT))

A NextGrid CHP system is the most affordable and most efficient CHP system on the planet today

While the majority of CHP systems on the market today will benefit customers by reducing emissions and increasing fuel efficiency, not all combined heat and power systems are created equal. Many CHP systems boast “high” combined efficiency but few actually deliver. The reason for this is what is known as the Carnot Cycle. Essentially it states that there is a maximum limit on the amount of energy that a heat engine can convert to useable energy. This is why CHP systems that use internal combustion engines and/or combustion gas turbines (both are types of heat engines) have maximum efficiency in the 75-80% range. While still good this does not come near the efficiency of a NextGrid CHP system at 95%.

NextGrid technology is unique from all other CHP technologies today. A NextGrid CHP system utilizes the revolutionary Green Turbine. This is a micro-steam turbine (about the size of a football) that uses steam to generate heat and electricity. They operate on what is known as the Rankine Cycle.

Our steam generators are the most fuel efficient in the world. Up to 95% of all of the fuel used is converted to either heat and/or electricity. This is why our customers can save thousands of dollars a year on their energy bills. Our systems generate small amounts of steam similar to the way an espresso machine does. This means that the steam is never stored but is released into the turbine as soon as it is created. Because the steam is not stored there is never any danger from steam related explosions.

Higher efficiency means lower operating costs for business owners. This also means reduced greenhouse gas emissions (GHG) including NOx and Carbon Dioxide. NextGrid CHP systems have the highest fuel efficiency and lowest carbon emissions of any combined heat and power system on the planet. In fact our NOx emissions are between only 0-3 parts per million!

Micro-Steam Turbine

NextGrid’s CHP systems deliver the highest quality of electricity by utilizing patented micro-steam turbines. Our micro-turbines use steam (similar to steam from an espresso machine) to generate electricity the same way your local utility does except on a much smaller scale. However unlike the electrical utility almost all of the heat is recovered and made available for space heating or for domestic hot water.

A NextGrid micro-turbine is extremely rugged and can last for up to fifty years. Built from machined aluminum, they have only one moving part and require almost zero maintenance.

Permanent air magnets are used resulting in no need for any lubrication. There are no spark plugs, air filters or engine oil needing to be replaced.

NextGrid’s superior CHP technology is affordable, robust and requires little maintenance.

It offers superior performance in a very compact size enabling businesses and consumers real and affordable energy independence.

Our technology offers flexibility found in no other CHP systems on the market today

While NextGrid focuses on CHP systems that use clean burning natural gas and/or propane we have built some amazing technology for our clients. We can do this because our technology offers flexibility found in no other CHP systems on the market today. One of the key features of this flexibility is being able to use many different fuel types. This ability arises from the fact that NextGrid turbines are external heat engines. In a NextGrid CHP system fuel is combusted in a separate process outside of the turbine.

For example, NextGrid has developed combined heat and power systems that utilize biogas as fuel. In this case biomass is gasified using pyrolysis and converted into heat and electricity. This has profound implications for the environment which is drowning in unrecycled waste.

NextGrid Heat Recovery Steam Generator

NextGrid has also developed highly complex systems that utilize waste heat such as solid oxide fuel cells (SOFC). In these applications fuel is oxidized in a fluidized bed generating heat in then 800 degrees Celsius range. The heat is captured using a NextGrid Heat Recovery Steam Generator (HRSG). The heat is then converted into electricity. Waste heat applications represent a significant opportunity for industry interested in lowering their energy footprint, costs and emissions.

At NextGrid we are constantly innovating to improve our CHP technology. We are on the forefront of cutting edge technology as we strive to bring consumers and businesses real and affordable energy independence.


Multi-Unit Residential Buildings (MURBS) can benefit greatly from a NextGrid CHP system. Installing a NextGrid combined heat and power system in your condominium and/or apartment building can drastically reduce operating costs associated with space heating, hot water and electricity. Our highly efficient (~95%) combined heat and power systems ensure that resident will never be out of hot water and that critical systems will always have power. All NextGrid CHP systems are “Black Start” capable.

How Energy is Consumed

This means that they operate independent of the grid and require no outside power source to operate. If your condominium has an indoor pool, we have the ideal solution to help reduce your heating expenses while keeping the pool at ideal temperatures. Our CHP systems offer flexibility in their output and can modulate to meet hot water and space heating demands while providing a steady flow of high quality electricity. NextGrid CHP systems are the most environmentally friendly CHP systems available today. Our carbon emissions are the lowest on the planet. In fact our NOx emissions are 0-3 parts per million. (PPM) This is far below any other CHP system or regular water heater available today.

While the majority of businesses will benefit from CHP some will benefit more than others. Generally speaking, businesses that require a consistent supply of hot water and space heating or for their operations stand to gain the most.

Other benefits include:

A NextGrid CHP system is an ideal solution for hotel operators wanting to reduce their heating and electricity costs while ensuring their critical operations do not lose power during a grid-blackout
  • Reducing operating costs.
  • Ensuring hot water is available for guests at all times.
  • Providing reliable electricity for gaming venues, even during utility blackouts.
  • Improving energy efficiency and overall environmental performance.
  • Reducing future cost uncertainties by creating a hedge against fluctuating energy prices.
