Guides to energy storage controls, monitoring, and sizing
Each guide answers one question a developer, asset owner, or utility asks about battery storage and solar: what a component does, what a standard requires, or how to size a system. Every guide opens with a definition, cites primary sources, and is written by the engineers who build and operate these systems.
- Intellect OperateWhat Is a Battery Energy Storage EMS?A battery energy storage EMS decides when a battery charges and discharges and how much power it moves. What it decides, what it is not, and how it earns.Read the guide
- Intellect OperateEMS vs BMS vs SCADA vs PPC: Who Does What in a BESSThe four control layers in a battery storage plant: the BMS protects cells, the EMS decides dispatch, the PPC enforces grid code, and SCADA supervises.Read the guide
- Intellect EnFORMWhat Is a DAS in Solar?A solar DAS polls inverters, meters, weather stations, and trackers and logs the readings. Devices, protocols, sampling resolution, and who requires one.Read the guide
- Intellect PPCHow Does a Power Plant Controller Work?A power plant controller measures the point of interconnection, compares it to a setpoint or utility command, and dispatches inverters to meet grid code.Read the guide
- Intellect PPCIEEE 2800 Requirements for the Power Plant ControllerIEEE 2800 requirements that land on the power plant controller: frequency response, voltage control, ramp rate, ride through, and measurement data.Read the guide
- Intellect EnFORMSGIP Monitoring Requirements for Battery StorageSGIP Handbook monitoring rules for storage: 15 minute meter data, the Performance Data Provider, meter rules above and below 30 kW, and missing data.Read the guide
- Intellect OperateWhat Is Peak Shaving With Battery Storage?Peak shaving explained: how demand charges bill the highest 15 minute interval, how a battery lowers that peak, a worked example, and the failure modes.Read the guide
- Intellect PLANHow to Size a Battery for Solar Plus StorageHow to size a battery for solar plus storage: choose kW and kWh separately from load data, the solar profile, and the tariff, with a worked example.Read the guide
- Intellect OperateHow to Choose a BESS EMS: A Vendor ComparisonEleven battery energy storage EMS vendors compared on deployment model, segment, multiple OEM support, protocols, cybersecurity, and Guidehouse ranking, from their own published pages, with the questions an RFP should ask.Read the guide
- Intellect PPCPower Plant Controller Vendors Compared for Solar and StorageTwelve power plant controller vendors for solar and battery storage compared on form factor, grid codes named, control functions, protocols, response time, and redundancy, from their own published pages.Read the guide
- Intellect EnFORMSolar and Storage Monitoring Platforms Compared for C&ITwelve commercial solar and storage monitoring platforms compared on data source, storage support, control, alerts and ticketing, fleet size, pricing, and public API, plus which inverter OEM portals publish an API.Read the guide
- Intellect OperateHow to Commission a Battery Storage Site in an EMSSeven steps turn an empty EMS project into a dispatchable battery site: project record, equipment library, single line diagram, algorithms, tariff, interfaces, and checks.Read the guide
- Intellect OperateMonitoring, Simulation, and Operation: The Three EMS Run ModesA storage EMS runs in one of three modes: monitoring reads and records, simulation runs the full control stack against a simulated plant, and operation moves real power.Read the guide
- Intellect OperateHow EMS Dispatch Algorithms, Tasks, and Operator Panels WorkIn a storage EMS an algorithm is dispatch logic written as code, a task is that code on a schedule, and an operator panel is the algorithm’s own dashboard. How the three fit together.Read the guide
- Intellect OperateHow to Enter a Time of Use Tariff in a Storage EMSA storage EMS treats the tariff as a control input. How rate seasons, day groups, and time of use periods are entered, with a worked two season commercial example.Read the guide
- Intellect OperateHow an EMS Publishes Site Data to SCADA over Modbus TCPAn EMS Modbus server publishes site power, energy, state, setpoints, and alarms to a plant SCADA or historian from one address. Byte order, address base, register maps, and access control.Read the guide
- Intellect OperateEMS Cybersecurity: Roles, MFA, Audit Logs, and EvidenceWhat cybersecurity looks like inside a battery storage EMS: access tiers and permissions, password and lockout policy, multifactor authentication, a hash chained audit log, and evidence for reviewers.Read the guide
- Intellect OperateReading Events, Timelines, and Daily Records in a Storage EMSHow a storage EMS records what happened: charts for any measurement, an event log with severities and device alarm payloads, a timeline for context, and daily records with exportable reports.Read the guide
