Water pumping, treatment and conveyance are among the largest energy and cost outlays for many local and regional municipalities. Electricity time-of-use rates and peak pricing tariffs are driving those costs even higher. This case study describes how Monterey Regional Water Pollution Control Agency (MRWPCA) implemented a process data monitoring and control solution in order to analyze and optimize energy use, reduce deployment costs and save operational expenses.

Enegia Group Oy was required to provide optimized energy efficiency improvements to clients with dispersed locations.

Steel fabrication plant processing 160MT to 200MT of steel per month.Plant wants to reduce spend on electricity. Evaluated solar panels, but project dropped due to ROI period.Plant has APFCRs to maintain a high Power Factor.

Building energy management systems (BEMS) provide real-time remote monitoring and integrated control of a wide range of connected systems, allowing modes of operation, energy use, and environmental conditions to be monitored and modified based on hours of operation, occupancy, or other variables to optimise efficiency and comfort. Building energy management systems can also trigger alarms, in some cases predicting problems and informing maintenance programmes. They maintain records of historical performance to enable benchmarking of performance against other buildings or across time and may help automate report writing. BEMS are often integrated with building automation and control (BAC) systems, which have a broaded scope of operations.

Energy management systems (EMS) enable operators of electric utility grids to monitor, control, and optimize the performance of power generation, storage, and transmission. These systems collect energy measurement data from utility infrastructure and customers to leverage applications that determine the most cost-effective configuration of power production, transmission, and distribution throughout the network, considering the required criteria for system stability, safety, and reliability. An EMS typically provides the information and computation capability to perform real-time network analyses, to provide strategies for controlling system energy flows, and to determine the most economical mix of power generation, power purchases, and sales. Wide area management control is used in digital grids to provide real-time data for applications to provide context-specific insights. It collects data that are visually synchronized with GPS signals and maps, analyzes data based on key criterion, provides real-time evaluation of voltage stabilization and minimum load shutdown of the capital area, and forecasts system issues through real-time analysis. These analysis and information can be used to make decisions and control the system in real time, improving system liability and avoiding blackouts during faults.

Energy storage management systems store and distribute energy from different sources to be integrated for use when it is needed. This is especially useful for energy sources that cannot produce energy on demand, such as solar and wind energy. With energy storage management systems, the energy generated in the day will be made available to use at night, matching demand with supply and providing energy in a more sustainable manner. Energy storage management systems deployed in remote areas can also power local IoT devices without rechargable batteries by storaging and distributing power as needed, increasing the availbility of IoT devices.
