Energy Management System. The CAISO shall install a computerized Energy Management System (EMS) to monitor transmission facilities in the CAISO Controlled Grid. A Participating TO may at its own expense and for its own internal management purposes install a read only EMS workstation that will provide the Participating TO with the same displays the CAISO uses to monitor the Participating TO’s transmission facilities.
Energy Management System. If a Facility is managed by an energy management system, then the Benefiting Party shall advise the Owning Party on its desires for controlling the electrical and mechanical systems for areas of its use. The Parties shall cooperatively determine and appropriately update how the mechanical and electrical systems for the shared-use areas shall be controlled based on ongoing activities in the building.
Energy Management System. (EMS) Facilities The following is a detailed summary of the Energy Management System Facilities needed to interconnect the Interconnection Customer with the NWE system.

Energy Management System. The EMS, also referred as the SMILE backend, is the infrastructure that is responsible for handling all the data produced in the Madeira demonstrator. The main objectives for the EMS are: • Provide secure storage to the data generated in each of the different pilots. This includes, but it is not limited to, energy consumption, solar PV production, EV charging, and battery status. • Provide a secure mechanism to access the pilot data. This data can be used, for instance, to populate the different end-user applications, or to provide data to our own XXXX control algorithms, or third-party systems (e.g., Route Monkeys’s forecasting algorithms). 1 ModBUS RTU, xxxxx://xxx.xxxxxxxxxxxxx.xxx/technologies/modbus-rtu/ The EMS backend is a flexible data storage and querying system, intended to allow the creation of products/services on top of the data generated in the different pilots. It consists of four main entities: producers, devices, sources, and schemas: • A producer is a user that can be related to a house or pilot location and has a registered account in our database. Producers are associated with devices (a producer can have many devices), also registered in our database. • Each device refers to a physical device installed at the producer infrastructure. The devices are responsible to send consumption and/or production data to our server, which stores the information in our database, to a source. • A source is basically a collection of data that stores information about power consumption/production for a specific type of device and is built based on a schema. • A schema defines which fields of data (e.g. timestamp, power consumption, power production, or others) and the type of data (float, string, etc.) the collection (source) will store in the database, so each source can have a different schema, giving us greater flexibility. For the SMILE project, a new instance of PRSMA’s backend was deployed in a cloud hosting service from Linode2. The nature of the EMS favors configuration over custom implementation. Therefore, most of the efforts so far are focused on correctly configuring the EMS for SMILE, and on building the user interface for users and administrators. Some security concerns were addressed in our system, starting with the usage of HTTPS to ensure the protection of the privacy and integrity of the exchanged data while in transit between the client and the server. Authentication is necessary for producers and devices, to prevent spurious data from...
Energy Management System. All the Madeira pilots will rely on the SMILE EMS, as described in section 2.1.2.

Energy Management System. Demand Controlled Ventilation M&V Option : NEMVP-B (continuos) Measurement Boundary: Retrofit isolation – Project savings will be determined within the measurement boundary that encompasses only the spaces temperatures and unit status affected by the energy project. Measured Parameter: Continuous measurement of CO2 levels and outside air damper Interaction: with Temperature Setback Measuring Equipment: Energy Management System Measuring Equipment Accuracy: ±3% of measurement range Measuring Equipment Calibration: Not applicable. Measurement Period: 15 minute samples Measurement Frequency: Continuous measurement Measurement and Verification Details: Pre-Installation Activities: During detail audit on site it was documented via interviews that the systems were manually started based on building operating schedule. Post-Installation Activities: Building Management system will continuously monitor post-retrofit CO2 levels and outside air damper position. The date-time stamp will be included to differentiate occupied/unoccupied and summer/winter periods. Formulas in the DEA will be used to calculate the savings
