Renewable natural gas (RNG) is an alternative net-zero emissions option for dual-purpose microgrids. The host customer achieves required long-duration power availability while reducing its costs for emergency backup through grid stability services.įleet operators also expect new load growth from transportation to be satisfied with net-zero emissions sources. This virtuous ecosystem benefits the local business and broader community. ![]() The revenue from these grid services reduces the costs for resiliency, making dual-purpose microgrids more affordable. They also provide service to grid operators, generating cost-offsetting revenue streams. Many companies, including mine, are building microgrids to serve power needs. These services help support grid stability and lower costs for EV charging site. The dual-purpose is power resiliency for the owner of an EV charging site and revenue-generating grid stability services for the larger grid. They are a local power generation platform that can overcome long-duration power outages, while also providing needed grid stability services. ![]() However, that potential is limited by current grid pricing structures that remain slow to change.įortunately, dual-purpose microgrids can help address grid reliability challenges, the need for additional local power capacity and cost management. Taking advantage of digital technologies, the exchange of data between grid, vehicle and charging infrastructure can be used to increase the efficiency of the transportation and energy sectors. Many aren’t designed to access the value EVs can provide the grid through smart charging and vehicle grid integration technologies, which use the flexibility of EV charging loads to provide ancillary grid services ranging from demand response to frequency regulation. Many utility rate structures can also penalize the load profiles EV charging creates, which leads to increased costs and challenges for commercial EV charging-site hosts. That creates significant uncertainties for fleet managers. ![]() New substations are needed, which could take two to four years to design and build. The time it takes to boost local capacity - anywhere from a few months to several years - must be considered. More investments in modernization are needed to meet demand.
