Tri-Technic has proven success and experience in navigating through complex, challenging, and schedule-intensive power plant construction, refurbishment and maintenance projects; including combustion and steam turbines; combined heat and power – CHP, co-generation plants, internal combustion engine-generators, whether diesel fueld, bunker oil or JP-5/8 fueled, or hydroelectric plants; including all balance of plant and fuel storage facilities; for utilities, industry, and government agencies.

We are adept at controlling the convergence of multiple construction disciplines. We maintain tight project controls and closely manage subcontractors, field personnel and staff allowing us to meet our clients’ highest expectations for safety, quality, schedule, budget and productivity, as required for every project.

All projects are completed on time and within budget. Tri-Technic has earned a valued position in the industry, because we control the details, and adhere to the fundamentals; this is the formula for success on every project, no matter how big or small; the fundamentals always work.

Green energy is rapidly evolving and will someday supplant conventional coal and natural gas as the dominant energy resource nationally and globally, as new technologies are developed and implemented. Government mandates to increase green energy indicate a clear commitment to reducing our national carbon footprint, as well as bringing clean, renewable energy sources to people around the globe.

With the exception of hydroelectric, hydrogen fuel cells, thermal solar, tidal and wave power, and geothermal generation, which are very complex systems, the predominant renewable energy sources in the market are wind and photo voltaic solar (PV). These are certainly products of advanced technology, inside their patented assemblies, but both have become simple basic commodities from a construction and installation perspective, which is a good thing for the energy industry. Costs must come down, in order for renewables to be viable and meaningful in the national and global energy mix, and commoditizing them is the right evolution.

Just about anyone can put the components together and make them work, but doing so on a utility / grid  scale, on time, on budget, with high levels of safety and quality is quite a different matter. “Utility scale” takes a team like Tri-Technic to effectively bring them into reality. The more complex alternative energy sources; hydroelectric, hydrogen fuel cells, biomass, thermal solar, tidal power, wave energy, waste to energy, geothermal and the like, are all less complex than combustion turbine or steam turbine plants and thus are well within our considerable expertise. Based on Tri-Technic’s related expertise, we are well positioned, ready and able to perform very well in the construction of any alternative energy project. Whether bid-build or design-build is needed, Tri-Technic is an exceptional choice.   

Reliability, quality, and adequate, if not abundant energy supply availability, at reasonable cost  are the directives that guide our national and global energy delivery systems.  Tri-Technic is and has for many decades been deeply involved in the delivery of electrical energy, from all of its generation sources, through the complex national, regional and local energy grid systems, with all related transmission, distribution, industrial / facilities substations; from 500KV interstate transmission systems, down through 4KV local industrial / facility / campus grid delivery systems, down to the low utilization and control voltages required to bring energy from where it is produced, to exactly where it is needed, safely and efficiently, to perform the heavy work required by a civilized society; keeping the wheels of progress turning.

Whether located hundreds of miles apart and applied for Long Haul Power Transmission connected via overland tower lines or submarine cables, or applied back-to back for grid synchronization, Tri-Technic is experienced in building and retrofitting HVDC Converter Stations.

We have completed Converter projects through 3,100MW at 500kV in the U.S. and we have demonstrated the capability to successfully complete projects into the largest MW and UHV ranges found in the world today. We are the Experts at Building & Retrofitting HVDC Converter Stations Our capabilities also assure success in building or retrofitting SVCs, the HVDC Converter’s smaller cousin. Whether the application requires conventional thyristor valve converters or the newer Insulated Gate Bipolar Transistor (IGBT) based converters, Tri-Technic is able and willing to provide these services and apply our expertise anywhere in the world

Chemical Storage includes batteries, which include dozens of diverse chemistries in the market, Li-Ion, lead-acid, redox flow, metal-air, and others; hydrogen; ammonia; bio-energy and the like. Chemical Storage is currently effective from 4 and up to 8 hours in limited application but becomes cost prohibitive beyond these limits. The exception to this rule is for hydrogen, which can potentially store energy for years. 

Thermal Storage includes; steam, hot water, molten salt, rock storage and similar heat-sink media; ice, chilled water, refrigerant and other thermal fluid transfers. Stirling engines; to geothermal and all related technologies. Thermal Storage is effective from several hours to several days. Beyond that point it loses its effectiveness.

Conventional generation, as we have all grown up with; Coal, Natural Gas, Fuel Oil, Nuclear produces fuels. Extracting, processing / refining, transporting, storing, and using it to serve our needs when and where we need energy. This “Fuels Storage”, is simply a re-deploying of energy that is latent in the earth.

This form of energy storage is the most effective and robust. It can and routinely does store energy for weeks, months, years. It is important to note, that it takes a considerable amount of energy to gather and re-deploy all forms of this type of energy.

Mechanical Storage is probably the most diverse and versatile of all energy storage categories. This group would include gravity storage. Gravity power has many forms including pumped hydro and similar technologies such as inertia storage, including flywheels and synchronous condensers. Similar equipment including compressed air, such as for powering air-motors or ram-jet enhancements to combustion turbines.

This short list encompasses literally hundreds of mechanical designs that can scale from small distribution connected storage equipment, up to very large transmission source equipment. These technologies can provide energy storage from a few minutes to many hours to potentially months. 

Electrical Storage, although we seek to store this form of energy, it is the most limited of the storage media, generally limited to super-capacitors, capacitors and reactors. These solutions can only store energy from a few cycles to a very few minutes but for grid support, they certainly have their value. 

These microgrids never connect to the Macrogrid and instead operate in an island mode at all times because of economic issues or geographical position. Typically, an “offgrid” microgrid is built in areas that are far distant from any transmission and distribution infrastructure and, therefore, have no connection to the utility grid. Studies have demonstrated that operating a remote area or islands’ off grid microgrids, that are dominated by renewable sources, will reduce the levelized cost of electricity production over the life of such microgrid projects.

Large remote areas may be supplied by several independent microgrids, each with a different owner (operator). Although such microgrids are traditionally designed to be energy self-sufficient, intermittent renewable sources and their unexpected and sharp variations can cause unexpected power shortfall or excessive generation in those microgrids. This will immediately cause unacceptable voltage or frequency deviation in the microgrids. To remedy such situations, it is possible to interconnect such microgrids provisionally to a suitable neighboring microgrid to exchange power and improve the voltage and frequency deviations. This can be achieved through a power electronics- based switch after a proper synchronization or a back to back connection of two power electronic converters[18] and after confirming the stability of the new system. The determination of a need to interconnect neighboring microgrids and finding the suitable microgrid to couple with can be achieved through optimization or decision making approaches.

Community Microgrids can serve up to a few thousands of customers and support the penetration of local energy (electricity, heating, and cooling). In a community microgrid, some houses may have some renewable sources that can supply their demand as well as that of their neighbors within the same community. The community microgrid may also have a centralized or several distributed energy storages. Such microgrids can be in the form of an ac and dc microgrid coupled together through a bi-directional power electronic converter.

The focus of campus microgrids is aggregating existing on-site generation with multiple loads located in tight geography in which owner easily manage them.

These types of microgrids are maturing quickly in North America and Asia Pacific; however, the lack of well –known standards for these types of microgrids limits them globally. Main reasons for the installation of an industrial microgrid are power supply security and its reliability. There are many manufacturing processes in which an interruption of the power supply may cause high revenue losses and long start-up time. Industrial microgrids can be designed to supply circular economy (near-)zero-emission industrial processes, and can integrate combined heat and power (CHP) generation, being fed by both renewable sources and waste processing; energy storage can be additionally used to optimize the operations of these sub-systems.

These microgrids are being actively deployed with focus on both physical and cyber security for military facilities in order to assure reliable power without relying on the Macrogrid.
