Distributed Energy Resources (DERs)

Small-scale, decentralized electricity generation and storage technologies located at or near the point of consumption, such as rooftop solar or wind.

Combined Heat and Power (CHP)

Also known as cogeneration, it uses a primary fuel to generate electricity and captures the resulting heat for local heating or industrial processes.

Substation Automation System (SAS)

A system using microprocessor-based devices and networks to automatically control, protect, and monitor all equipment within a substation.

Intelligent Electronic Device (IED)

A microprocessor-based device at the Bay Level of an SAS designed for specific tasks like protection, control, or fault recording.

IEC 61850

The global, non-proprietary standard for communication in substations, ensuring interoperability between devices from different manufacturers.

GOOSE (Generic Object Oriented Substation Event)

A high-speed, peer-to-peer messaging protocol under IEC 61850 used for time-critical functions like protection tripping.

Smart Cities Mission

A Government of India initiative launched in 2015 to develop cities with sustainable and citizen-friendly solutions through digital and electrical engineering innovations.

Special Purpose Vehicles (SPVs)

Intelligent Motor Control Center (iMCC)

An advanced MCC integration smart relays, communication networks, and sensors for real-time monitoring and predictive diagnostics.

Edge Computing

Processing data locally near the source (e.g., inside an MCC) to enable real-time diagnostics and reduce network latency and bandwidth use.

Zigbee

A low-power, mesh-network wireless protocol suitable for industrial monitoring and self-healing communication in smart systems.

Power Purchasing Agreement (PPA)

A legal contract between an electricity generator and a buyer defining commercial terms, delivery schedules, and payment for electricity over a long term.

Cross-subsidy

A pricing mechanism where one category of consumers pays more than the cost of supply to subsidize lower prices for another category.

Wheeling Charges

Transportation charges associated with the use of the transmission owner's system to move electricity.

Fuel Adjustment Charge (FAC)

A variable component of an electricity bill based on the changing price of fuel or coal used in power generation.

Net Metering

A billing mechanism that credits renewable energy system owners for the excess electricity they feed back into the grid after their own consumption.

Gross Metering

A billing mechanism where power consumed from the grid and power generated and fed to the grid are recorded and billed separately.

Power Factor Correction (PFC)

The optimization of energy use by reducing reactive power, typically using capacitor banks, to improve overall system efficiency.
