Press Release11 October 2021Siemens EnergyOrlando
Siemens Energy installs world's first leased rapid response transformers, allowing a large generating facility to return to service
The Pretact transformers are designed to serve as replacement
equipment in the event of transformer outages. These are multi-voltage, modular
transformers that can be deployed anywhere and configured to match customer
requirements using biodegradable insulating fluids that reduce environmental
risks during transport and operation. They also offer smart technology that
transmits real-time data to a cloud-based storage, analytics and visualization
platform to allow for performance optimization.
Siemens Energy is leasing the transformers to the facility,
which made it possible for the power plant to return to service in less than
two months from a forced outage caused by a failure of their existing, conventional
GSU transformer. The Pretact Sensformers will be in service until Siemens
Energy delivers a new, permanent replacement transformer. The project is part
of the Pretact transformer program that aims for rapid deployment of equipment
to minimize outage times.
Society depends on reliable electricity, as long-term power
interruptions can have disastrous consequences. Siemens Energy is focused on
improving grid resiliency by offering mobile plug-and-play units that can
quickly restore power after a failure at either a substation or generating
facility or to avoid disruptions during grid maintenance and upgrades. Compared
to conventional transformer replacements, which might not be available for 9 to
12 months after an outage, the easy-to-install Pretact technology allows for
rapid reinforcement of a power grid in an emergency or due to unexpected events,
as well as during seasonal peak loads or when networks expand.
Wade Lauer, senior vice president of Siemens Energy’s Transmission
division in North America said, “This is the first time a multi-voltage GSU has
been leased to customers as a flexible transformer replacement option. Being
able to rapidly deploy innovative replacement equipment is key to enhancing
grid resiliency here in the U.S. so that we can help our customers keep the
lights on.”
Scott Gray, operations manager for Siemens Energy
Transformers USA said, “Upon notification of the failure the Siemens Energy
team was able to confirm a technical match, negotiate terms, mobilize to the
storage location, and prepare the units for shipment within 2-1/2 weeks. The equipment
was delivered to the customer site the next week, and was fully assembled, oil
filled and tested in less than two weeks from mobilization to site.”
