Glossary & Disclaimer
Learn about Glossary in the energy transition.
- Base Load - The minimum level of demand on an electrical grid over a span of time
- Behind the Meter - refers to devices (typically solar arrays and batteries) that are deployed on-premises so that energy is produced and consumed on-site without passing through the electric meter or the grid.
- BESS - Battery Energy Storage Systems
- Brownout - a drop in voltage level
- Bulk Energy Shifting - the movement of energy through the system at off peak times
- CAES - Compressed Air Energy Storage
- CCS - Carbon Capture and Storage
- COD - Commercial Operations Date, when revenues begin to flow from a new solar/wind or other facility
- Carbon Negative - removes more CO2 from the atmosphere than it adds to the atmosphere
- Carbon Neutral - removes an equal amount of CO2 from the atmosphere as it adds to the atmosphere
- Carbon Positive - adds more CO2 to the atmosphere than is removed from the atmosphere
- Curtailment - the discarding of energy due to oversupply of electricity from renewable energy sources
- Demand Management - the adjustment of electricity consumption during periods of high demand or supply constraint
- Demand Curve - the daily pattern of aggregate electrical consumption from the grid (in graphical form)
- DER - Distributed Energy Resource
- DERMS - Distributed Energy Resource Management System
- Dispatchable - sources of electricity that can be programmed on demand at the request of power grid operators
- Drop-in fuels - Fuels that can be used in existing engines and fuel infrastructure without any modifications
- Downstream - The logical zone of the power grid where energy is consumed
- Energy Security - Access to a reliable, affordable, and sustainable supply of energy
- Energy Stockpiling - the process of storing energy in large quantities for later use
- Energy Transition - a broad term that describes a significant structural change to energy systems. The current Energy Transition is driven by the recognition that GHG emissions must be drastically reduced
- EV - Electric Vehicle
- FIT - Feed in Tariff (typically paid by Utilities for surplus solar power)
- Flatten the Demand Curve - reduce the spread between Peak Demand and Base-Load demand
- Front of the Meter - located on the Utility’s side of the meter, meaning that they supply or store energy for the grid operator
- GHG - Greenhouse Gas
- Grid - shorthand for electrical power grid
- Grid Operations - the process of monitoring, controlling, and maintaining the electrical grid to ensure a reliable and efficient supply of electricity to consumers
- HP - Heat Pump
- ICE - Internal Combustion Engine
- ISO - Independent System Operator
- LCOS - Levelized Cost of Storage
- LCOE - Levelized Cost of Electricity
- Li-ion - Lithium ion batteries
- Midstream - The logical zone of the power grid where grid stability is managed by operators
- NZE/"Net Zero" - Net Zero Emissions by 2050
- OEM - Original Equipment Manufacturer
- Peak Demand - the short daily period where the highest point of customer consumption of electricity occurs
- Peak Shaving - the reduction or smoothing out of peaks in electrical consumption by industrial & commercial consumers
- PPA - Power Purchase Agreement
- RNG - Renewable Natural Gas
- RTE - Round Trip Efficiency describes how much energy is retained when a battery goes through a full cycle of charge & discharge
- RTO - Regional Transmission Organization
- SCADA - Supervisory Control and Data Acquisition
- SMR - Small Modular Reactor
- Surge - a sudden spike in voltage
- TCO - Total Cost of Ownership
- Upstream - The logical zone of the power grid where energy is generated & supplied into the grid (wind, solar, hydro etc.)
- Utility - A company that engages in electricity generation and distribution of electricity for sale, usually in a regulated market
- VC - Venture Capital firms
- VPP - Virtual Power Plant
- VRB - Vanadium Redox Batteries
