The e-One Energy Digital Twin™ economic optimization is applicable to a wide variety of microgrids and distributed energy resources, regardless of whether your electric utility is regulated or not. In particular, it applies to a wide range of transportation, residential, commercial, industrial, and utility applications.
The electrification of the transportation sector is expected to accelerate dramatically in the next 10 years, especially in the medium (MDV) to heavy-duty vehicle (HDV) segment. This transformation is expected to challenge the capacity of the current power grids. But it also provides additional sources of ‘free’ distributed storage which the grid needs to operate reliably as it increasingly relies on distributed renewable intermittent generation. This capability can be monetized through the fleet providing multiple grid reliability services.
Our Energy Digital Twin™ optimizes the MDV and HDV fleet participation in the energy market and utility incentives when connected to the grid. Leveraging two-way charging (V2G), it turns an EV fleet into a revenue generator, while minimizing charging costs and demand charges at the same time. Furthermore, the fleet can be co-optimized with local generation, storage, and building loads to provide both resilience and additional economic benefits (V2X).
School buses are a perfect candidate for the above strategy. Federal and State mandates, supported by the EPA Clean School Bus program, aim at converting US school bus fleets (over 500,000 buses nationwide) to zero-emission by 2035. Most of those buses will be powered by electricity stored in batteries ranging from 175 KWh to 225 KWh per bus. Fleets of school buses have the advantage of spending a majority of the time in a parking lot, especially during the hot summer days. They are also a source of mobile backup power during major outages.
Energy consumption by the U.S. residential and commercial buildings represents the majority of the country's energy consumption. The transition to all-electric heating systems will increase further the demands on the power grids. Deployment of distributed generation and storage solutions contributes to increased resiliency at the local level but is further challenging to the grid operator, as those solutions are typically implemented behind the meter (BTM). The intermittency of such resources can create rapid fluctuations of the net load seen by the operator, reverse flows, and potential grid stability issues. Solutions deployed at the individual residence level do not scale well, can create havoc on the distribution grid, and are not applicable on a large scale in city neighborhoods, especially in underserved communities.
At the residential level, our e-One solution platform co-optimizes aggregated residential assets, including PV panels, storage (Electrical and thermal), and load flexibility, providing residents with resiliency, improved power quality, and lower energy costs. Conversely, it reduces or eliminates net load fluctuations and reverse flows.
At the commercial level, it combines building thermal and electrical storage with Building Management System, EV chargers, renewable generation, and Elevator Management System to provide capacity and ancillary services to the grid operator, together with lower energy costs and resiliency to the building owner.
The rapid electrification of transportation and buildings (residential and commercial), is placing additional stress on utility assets, requiring distribution utility companies to upgrade the capacity of their substations and distribution assets to accommodate the increased peak demand. Such upgrades are time-consuming and expensive. An increasingly popular scenario for utilities is the installation of battery storage to perform load-shifting during high peak seasons and defer capacity expansion investments. Our Energy Digital Twin™ platform co-optimizes utility operations with market participation. We expect to effectively double the annual economic benefit of the solution on an existing project.
More generally, our e-One solution platform enables a distribution utility or cooperative to view distributed energy resources and microgrids as energy nodes capable of providing various grid reliability services, either under grid operator control (Dynamic Load Management) or incentives driven (Self Dispatch).
Campus and military microgrids provide resilience and power quality to the campus critical loads and lower energy costs. Those microgrids are capable to separate from the main power grid during weather or cyber-related grid outages and serve as a source of ‘Black Start’ power during the post-event restoration of the main grid.
When the microgrid is connected to the main power grid, the Energy Digital Twin™ combines with our strategic partner's real-time microgrid control and optimization platforms to maximize utility incentives, energy market, and ancillary service revenues, while ensuring microgrid physical constraints are not violated. In islanded mode, the integrated solution ensures indefinite serving of the critical loads at the lowest possible cost.
Most importantly, the Energy Digital Twin™ is an invaluable tool to plan and optimize the design and operation of the microgrid. In particular, it permits the assessment of the impact of proposed expansions and various market participation scenarios.
