Industrial Intelligence Built and Delivered with Pride
Avista Realtime Systems LLC is an industrial controls and SCADA engineering firm delivering design-build automation systems for utilities, data centers, and industrial clients. Core services span SCADA design and implementation, advanced energy management systems, IIoT integration, power automation, and UL 508A control panel fabrication. Its aviCore managed-service platform delivers scalable monitoring and control for data centers, water/wastewater utilities, and electric municipalities, combining edge computing, predictive analytics, and industrial cybersecurity. Representative projects include a hospital distributed generation transfer trip system, transit authority advanced energy management, gas plant SCADA modernization, electric distribution SCADA integrating solar and EV infrastructure, and design-build tunnel ventilation control.
Healthcare
Installation and configuration of a Direct Transfer Trip system receiving commands from the utility via SEL RB link over fiber and relaying those commands to CHP and Solar unit breakers. Includes integrated metering for power, voltage, and related parameters, with all operational statuses and data transmitted to the utility SCADA system via wireless connection.
Transit
Design, implementation, and configuration of an Advanced Energy Management System gathering data from all transit authority traction power stations. Delivers alarm notifications, historical data storage, multiple reporting functions, and web-based access for both engineering and planning teams.
Oil & Gas
Modernization of a legacy gas system SCADA with approximately 1,000 screens and 10,000-plus data points, migrating to a virtual server cluster with a disaster recovery component. Includes a custom screen and database upgrade application, redundant historian servers for reporting and tracking, and a one-way data link to an isolated development system for safe testing of patches and changes before production deployment.
Electric Utilities
Design-build electric SCADA system monitoring and controlling transformers, high-voltage switchgear, medium-voltage and distribution panels, solar and EV infrastructure, transfer switches, and generators. RTUs distributed across the facility interconnect via a self-healing fiber ring governed by managed network switches, with the SCADA head-end integrated into the Building Management System. Scope spans design, submittals, panel and equipment manufacturing, programming, startup, O&Ms, and training.
Tunnels
Design-build ventilation control system covering two tunnels and an intermediary shaft, with all components including PLCs, gateways, HMIs, IOs, and data links specified for full redundancy. PLCs in tunnel mechanical rooms share IOs over redundant IO rings, supported by a dual data network and four HMIs across mechanical and fire rooms. Scope spans design, submittals, panel and equipment manufacturing, programming, startup, operation and maintenance, and training.
