Microgrids are certainly a trend on the North American continent, providing a secure supply of energy to businesses and communities within this microgrid, which is especially important with the growing frequency of natural disasters and possibility of blackouts in “macrogrids”.
Microgrids are decentralized power solutions that produce energy and supply it to the local consumers. Such microgrids can operate both in parallel with external centralized grids (macrogrids) and in an isolated (island) mode. In some cases, microgrids can transfer surplus of electricity to the macrogrids.
Development of local microgrids, in addition to improving the reliability of power supply, also allows to reduce carbon footprint, and often lower the cost of consumed energy.
Common major drivers for creating local microgrids are:
- need to improve the reliability of power supply or;
- desire to get away from expensive centralized energy sources, especially during peak consumption hours or;
- need to reduce the carbon footprint produced by the company / community through use of cogeneration as a more efficient way of generating energy compared to centralized sources or;
- possibility of combining traditional local cogeneration using gaseous fuels with renewable energy sources (e.g. hydrogen, biogas, fuel cells, sun, wind, etc.).
When reliable power supply is key
Gas engine solutions are especially relevant if your microgrid supplies energy where uninterrupted power is critical (for example – hospitals, data centers, process industries, etc.).
Jenbacher gas engines ramp up to full power output in just a few minutes, providing your microgrid with necessary power, when it is needed.
At the same time, Jenbacher gas engines are more environmentally friendly than diesel engines, because they have lower emissions. Therefore, gas engines are actively used in microgrids due to increasing environmental requirements.
Optimize your energy expenses wisely
Many grid clusters in the North American continent have dynamic electricity price levels, and of course there are certain seasons of the year and hours of the day when the cost of centralized energy peaks. In many cases, these spikes seriously increase the operating costs for microgrid consumers. The use of onsite power generation, and especially usage of gas engines in microgrids, allows stabilizing and better prediction for energy-related costs.
Since Jenbacher engines run on gaseous fuels, they can dynamically start up when needed to produce energy during peak hours. In many cases, compared to the industrial gas turbines, reciprocating gas engines are less sensitive to frequent starts and stops. As a result, the client gets the necessary maneuverability to operate in “peak-shaving” mode.
Green is clean
In the new decade, the environmental agenda is becoming more and more important. Companies and communities have to become more environmentally - responsible, meet public ecological requirements and make additional “green” commitments. Jenbacher takes the environmental agenda very seriously and we have a lot to offer to like-minded companies:
- Cogeneration. Our gas engines are efficiently working in Cogeneration schemes. Cogeneration or CHP is simultaneous production of heat and power (in addition to efficient electricity production, Jenbacher CHP systems convert the waste heat created during an engine’s operation into useful hot-water or steam). It is usually more efficient compared to separate production at electrical power plants and boiler houses. Cogeneration solutions based on Jenbacher engines work with total efficiency up to 90% and more, maximizing conversion of gas energy into useful power. As a result, it helps your microgrid to be more efficient and decrease the carbon footprint.
*Based on IEA ’16 electricity production figures for EU-28 and EIA ‘17 average power plant heat rate references
- Trigeneration. Depending on your needs, you might want to consider using combined cooling, heat, and power (CCHP) systems, also called trigeneration systems. Such system is a combination of cogeneration plant and absorption chillers. Jenbacher engines offer an efficient solution for generating air conditioning and/or refrigeration. Cogeneration equipment offers high efficiency and low emissions. Absorption chillers provide an economic and environmental alternative to conventional refrigeration with compression chillers. Combining those two elements enables excellent total fuel efficiency, elimination of HCFC/CFC refrigerants, and reduces overall air emissions.
- «Green» gases. Our engines do not only run efficiently on natural gas. They also work with biogas, landfill gas, wastewater gas, industrial syngas and other gases, converting greenhouse gases into useful energy and helping customers to achieve their environmental goals.
- Hydrogen. Jenbacher launched the first hydrogen-powered engine years ago. Our gas engines can run on a mixture of gas and hydrogen as well as on pure hydrogen. Most of the already installed engines, which run on natural and other gases, can be converted to run on a hydrogen.
Flexibility at hand
Jenbacher can work on new microgrid projects or projects dedicated to modernizing existing microgrids. In existing microgrids, electricity or heat generating equipment might be already installed. It could be an existing gas power plant, or renewable energy power plant (solar, wind, fuel-cell) or it could be a boiler house.
Flexibility is the key for integration purposes, and therefore Jenbacher solutions can be supplied as modules for installation inside a building or as ready-to-use cogeneration module in a container. In this way, Jenbacher engine solutions can be effectively integrated into the existing electricity and heat generation infrastructure. Moreover, containerized solution allows to shorten the time to a Commercial Operation Date if it is necessary.
Jenbacher gas engines can be synchronized with both local power generation equipment and external grid. An engine’s heat exchangers can be integrated into the existing thermal infrastructure of the microgrid to increase the overall efficiency or to achieve production targets if necessary.
Jenbacher modules are presented in a voltage ranging from 480V to 13.8kV allowing you to select the required voltage depending on your microgrid requirements, internal consumers, and external grid characteristics.
Power plants based on Jenbacher engines can be equipped with a master-synchronization system that allows the engines to synchronize with each other and with an external grid. In addition to that, power plants can be equipped with a master-control system that allows you to adjust the operating parameters of the engines and set a certain load profile if needed.
Power plant in your pocket
Jenbacher myPlant Performance Management's digital solutions allow you to monitor the status of your power plant. Service data collected from the engines is analyzed by Jenbacher service competence centers, which leads to better engine maintenance, allows solutions to many problems remotely, and as a result, increases the uptime of your power plant.
