US Army Corps of Engineers (USACE) have been using OpenSplice DDS for a major upgrade to the control system at the massive Grand Coulee Hydroelectric Dam project

One of the first customers to benefit from OpenSplice DDS v6 has been the US Army Corps of Engineers (USACE) who have been using it for a major upgrade to the control system at the massive Grand Coulee Hydroelectric Dam project.   

Grand Coulee is the largest power plant in North America, fifth largest in the world, with a total generating capacity of 6,809 megawatts via four different power houses containing 33 hydroelectric generators.

Grand Coulee Hydroelectric DamDave Brown, Chief Architect of the Generic Data Acquisition and Control System (GDACS) for the US Army Hydroelectric Design Center, commented "Around two years ago we selected DDS as the real-time publish/subscribe messaging middleware for the dam upgrade program, convinced that it was the right technology for our needs.  OpenSplice DDS met all our rigorous performance and acceptance criteria.  We went with the library based version of OpenSplice DDS v6 because of our need for an application solution that is simple to deploy.  The Grand Coulee Hydroelectric Dam project uses about 150 computers which makes ease of deployment very important to us.  Although we do not currently use the shared memory deployment model in our architecture we are encouraged in knowing that OpenSplice DDS v6 provides a stable, uniquely switchable shared memory option should we desire to change our architecture characteristics."

"To sum up: PrismTech provided us with a toolkit product – not consulting; their people listened, understood our unique application needs and supplied us with a DDS product solution that enabled us to deliver a state-of-the-art distributed control system."
