ETS has the technical and commercial expertise to implement both large scale Supervisory Control and Data Acquisition (SCADA) systems for large industrials, commercial buildings and facilities, mining and milling plants, water, natural gas, waste-water and electric utilities.  We have also developed and implemented Energy Management and Control Systems (EMCS) for various entities including the Municipalities, School Districts, Box Store Retail, Multi Retail Outlets Chains, and Cellular Repeater Installations.

ETS has twenty years experience in the automation and controls industry and has extensive experience developing controls projects from the conceptual technical scope and cost analysis to full engineering, design and construction with ongoing monitoring, testing and calibration, training and technical support. 

ETS has been responsible for the implementation of SCADA and fully automated controls for the Navy Public Works Center Southwest Division.  We are responsible for the complete controls as well as the networked operation of several manned and unmanned central plants and outlining utility infrastructure located at six different bases.  ETS has engineered, designed, constructed and implemented a combination of unlicensed wireless radio and internet networks utilizing a virtual private network (VPN) and a client/server application model to seamlessly link these facilities together.  Monitoring and control of the individual plants can be performed at any location using appropriate User Name and Access privileges across the wireless network.

ETS has worked with various protocols, operating systems, and hardware in order to implement SCADA for various clients.  ETS has designed and implemented solutions utilizing packet and serial communications with standard ASCII, Modicon Modbus, Allen Bradley and other IP protocols.  ETS has designed SCADA systems utilizing Ole’ for Process Controls (OPC) and field bus protocol standards as well as proprietary protocols. 

ETS personnel have been responsible for the development and implementation of high-speed serial networks utilizing the foundation field bus standards for the automation of water filtration systems.  ETS personnel were instrumental in the transition to an OPC client/server platform utilizing TCP/IP connectivity in client projects. 

ETS has implemented complete wireless distributed Energy Management Systems for commercial retail stores to optimize HVAC, lighting, refrigeration and process controls for both energy conservation and real-time demand side management.  These projects have been subsidized for both energy conservation and for active demand relief by the local utility company after actual monitoring and validation of system performance and savings was performed.  Communication to the system was accomplished using a single wireless cellular gateway to a wireless local area network of private radios for each remote terminal unit (RTU).

ETS has implemented complete wireless real-time electric meter reading systems for a converted military base which was privatized by a municipal utility.  Individual utility grade C&I meters were installed on each building and a wireless RF communication network was installed to allow remote meter reads.  The meter network allowed for real-time and pre-programmed meter reads for invoice and billing purposes as well as cost allocation.

• Retrofit of an existing Johnson Controls PLC with Modicon Momentium PLCs and communication network.  SCADA and automation of for Data Center cogeneration and central plant at the Navy’s North Island Naval Air Station Coronado.  The control system utilized a segmented Modbus Plus network with home runs to the HMI utilizing Modbus Ethernet. This plant includes four 650 KW reciprocating dual fuel natural gas and propane fueled generator sets for backup and peaking requirements, individual heat recovery boilers, three 600 ton absorption chillers, paralleling switchgear for electrical and thermal system operations from the generator sets.

• Wireless hardware and software for Southern California shopping malls for HVAC and lighting system control.  Supply included one hardwired internet-gateway and seventy wireless remote terminal units for individual HVAC control and eight wireless RTU’s for lighting control. Real-time internet-based local and remote monitoring and control capability using web interface or server interface software.  Systems performed both control for energy conservation and real-time control for demand relief.  Hardware and software included on-board energy consumption reporting for actual monitoring and validation for utility rebate programs.

• Complete Energy Management Control system for a municipality in Southern California.  Supply included 17 wireless 802.11 internet gateways for the city’s buildings and over 100 wireless remote terminal units for individual HVAC or lighting panel control. Real-time internet-based local and remote monitoring and control capability using web interface or server interface software.  Systems performed both control for energy conservation and real-time control for demand relief.  Hardware and software included on-board energy consumption reporting for actual monitoring and validation for utility rebate programs.  Program was performed under a 10-year guaranteed savings and maintenance contract.

• Removal of obsolete tone telemetry systems and implementation of SCADA integration of pump stations for California American Water Company, Monterey Division, Duarte, San Marino, Thousand Oaks Division utilizing a licensed radio network, Pacific Bell’s private Frame Relay Service and ADN networks configured in multi-drop configurations.  Hardware was largely Allen Bradley PLCs and Wonderware HMI Software.
