Frequently asked questions
A virtual power plant is a network of decentralized, temporary or permanent energy assets – including generators, batteries, and a control system – that operate together as a single energy source.
In transmission and distribution applications, virtual power plants can be deployed to support additional load during upgrades, emergencies, or congestion.
During scheduled upgrades to your transmission or distribution system, utility companies can maintain continuous service by using temporary energy solutions.
These solutions act as stopgaps, supplying energy to affected areas while permanent infrastructure is offline.
Solutions may include mobile generators, temporary substations, load banks, and distribution panels, all of which can be tailored to match your energy, sustainability, and technical needs.
Pre-positioning and engineering these solutions so that they fit seamlessly with your existing T&D assets makes it much easier to carry out essential capital improvements without compromising customer reliability. You can also avoid triggering performance penalties tied to reliability metrics like SAIDI and CAIDI.
We provide a full suite of engineered energy and temperature control solutions for both planned and unplanned T&D events.
For scheduled maintenance or capital upgrades, we deliver temporary energy solutions like virtual power plants that maintain grid continuity while work is performed.
For emergency situations such as hurricanes, substation failures, or unplanned outages, we mobilize rapidly with storm restoration support. This support can include generators, BESS, and load-sharing infrastructure – whatever you need to restore service and reliable energy access. This turnkey support helps utilities meet restoration targets, maintain service quality, and protect end-user experience.
Temporary energy solutions are a key part of modern grid resiliency planning. They provide utilities with fast-response energy that can bridge supply gaps during system failures, natural disasters, or long-term infrastructure upgrades.
By using modular generators, BESS, and microgrid technologies, you can avoid prolonged outages, stabilize fluctuating loads, and maintain voltage balance.
Overall, temporary power solutions give utilities the agility and control needed to respond dynamically to both predictable and unpredictable disruptions.
