The energy industry is going through a period of rapid change. Markets are deregulating, new technologies like battery storage and distributed energy resources are scaling, and sustainability expectations are increasing. With this transformation has come a surge of acronyms and technical terms in contracts, tariffs, and sustainability reports that can feel overwhelming if you are new to the industry. Yet these terms directly affect how much you pay for energy and how you manage risk.

Why energy jargon matters

Energy literacy is becoming a practical business skill, not just a technical one. When decision- makers understand the language of tariffs, capacity tags, renewable energy certificates, and carbon markets, they are better equipped to evaluate proposals, assess risks, and align procurement with broader business objectives.

Misunderstanding the difference between demand and energy charges, for example, can lead to unexpected costs. Confusing a fixed price with an index-based contract can expose your business to price volatility you thought you had avoided.

This guide is designed to make that process easier. It organizes common terminology into five core categories and explains each term in clear, plain language. As you become familiar with the industry, use this glossary as a reference to navigate jargon and make more informed decisions.

Commonly confused terms

Many energy and sustainability terms sound similar but have very different implications for cost, risk, and reporting. The pairs below are some of the most commonly confused, and getting them right can make conversations with suppliers and internal stakeholders much more straightforward.

1. kW vs kWh: power vs energy
   • kW (kilowatt) measures power – how much electricity is being used or produced at a specific moment. It reflects the “size” or capacity of equipment, such as a 500 kW solar system or a 1,000 kW (1 MW) generator.
   • kWh (kilowatt-hour) measures energy over time – how much electricity has been used or produced over an hour, day, or month. This is typically how your consumption appears on an electricity bill.

   Why it matters:
   kW is closely linked to demand charges and system sizing; kWh is tied to usage charges and total consumption. Mistaking one for the other can lead to incorrect expectations about project output, savings estimates, and tariff impacts.

2. Demand charge vs energy charge: paying for peaks vs volume
   • Demand charges are based on your highest kW draw (peak power) during a billing period. They reflect the cost of being ready to serve your maximum load.
   • Energy charges are based on the total kWh consumed over the period. They reflect the cost of the energy you actually use.

   Why it matters:
   Reducing kWh alone may not significantly lower your bill if your peak demand stays high. Understanding this distinction is essential for designing effective load management, shifting processes, or using on-site generation and storage to reduce peaks.

3. Fixed price vs index (and block & index): price certainty vs market exposure
   • A fixed price contract sets a single, agreed price for each kWh over the contract term. It offers budget certainty, but you may miss out on potential market dips.
   • An index contract ties your price to a market benchmark, so your cost moves with wholesale prices. This can provide savings when markets fall, but exposes you to volatility when prices rise.
   • A block & index structure combines the two: you fix a portion of your expected load (the “block”) and leave the rest on index. This offers a partial hedge, balancing certainty and flexibility.

   Why it matters:
   Misunderstanding these structures can lead to unexpected cost swings or missed risk management opportunities. It is important to be clear on how much of your load is fixed, how much is floating, and how that aligns with your risk tolerance and budget objectives.

4. Net-zero vs carbon neutral
   • Net-zero typically refers to emissions reductions across scopes, with any remaining emissions balanced by high-quality removals. It focuses on transforming operations and supply chains over time.
   • Carbon neutral usually means that some or all emissions are balanced with offsets, without specifying the level of internal reduction required beforehand.

   Why it matters:
   These terms are often used interchangeably, but they signal different levels of ambition and action. Being precise helps manage expectations with investors, customers, and employees, and supports credible long-term climate strategies.

5. RECs/EACs vs carbon offsets
   • RECs (Renewable Energy Certificates) and EACs (Energy Attribute Certificates) represent the environmental attributes of renewable electricity generation. Purchasing and retiring them allows organizations to claim consumption of renewable electricity, primarily affecting Scope 2 accounting.
   • Carbon offsets represent emissions reductions or removals achieved by specific projects (such as reforestation or methane capture) that are used to compensate for emissions elsewhere, often in Scope 1 or Scope 3.

   Why it matters:
   Both instruments support climate goals, but they address different parts of your footprint and are accounted for differently. Using the right tool for the right scope is important for accurate reporting and credible sustainability claims.

6. PPA vs VPPA (virtual PPA)
   • A Power Purchase Agreement (PPA) is typically a physical contract for electricity: you agree to buy power from a specific renewable project, often with delivery tied to a grid location relevant to your operations.
   • A Virtual PPA (VPPA) is a financial contract rather than a physical supply arrangement. You continue to buy your electricity from your usual supplier, while the VPPA settles the difference between a fixed price and a market price, and you usually receive the associated RECs or EACs.

   Why it matters:
   Both structures can help bring new renewable projects online and support your decarbonization strategy, but they differ in how they affect energy sourcing, price risk, accounting treatment, and operational complexity. Being clear about whether a proposal is a PPA or VPPA helps you align it with your risk policies and internal approval processes.

    

Key energy terms you should know

To navigate the energy market effectively, it’s helpful to understand some key terms:

• Deregulation refers to the process of allowing competition in energy markets, giving businesses the option to choose their suppliers.
• Kilowatt-hour (kWh) measures electricity consumption and is commonly used in billing.
• British Thermal Unit (BTU) is a measure of heat energy used for natural gas pricing.
• Tariff is the rate structure set by suppliers and utilities for energy service.

Core categories of energy jargon

Energy management jargon

kW (Kilowatt)/ MW (Megawatt) (if using only one unit of measurement, then use kW) 
Measures the rate at which electricity is being used or produced at a specific moment.

• kW = kilowatt = 1,000 watts
• MW = megawatt = 1,000 kW (or 1 million watts)

kWh (Kilowatt-hour)/ MWh (Megawatt-hour) (if using only one unit of measurement, then use kWh)
Measures the amount of electricity used or produced over time.

• kWh = using 1 kW for 1 hour
• MWh = 1,000 kWh

BTU (British Thermal Unit)
A small unit of heat energy, used in natural gas and heating. It’s the amount of energy needed to slightly raise the temperature of water.

Therm
A billing unit for natural gas, equal to 100,000 BTU. Many gas utilities bill consumption in therms.

Dth (Dekatherm)
Another common gas billing unit, equal to 10 therms, or 1,000,000 BTU. Some markets use therms, others use dekatherms; they’re just different ways of counting the same underlying heat energy.

Standard Cubic Foot (SCF)/Ccf/Mcf
These measure the volume of natural gas, not its energy content, although the two are related.

• SCF (Standard Cubic Foot)
  One cubic foot of gas measured under standard conditions of temperature and pressure (a “normal” reference point).
• Ccf
  Stands for “hundred cubic feet” (the first “C” is “centum,” Latin for 100).
  1 Ccf = 100 cubic feet of gas.
• Mcf
  Stands for “thousand cubic feet” (the “M” comes from the Roman numeral for 1,000).
  1 Mcf = 1,000 cubic feet of gas.

Demand
The requirement for energy as an input to provide products and/or services.

Power
The rate of producing, transferring, or using energy, most commonly associated with electricity.
Power is measured in watts and often expressed in kilowatts (kW) or megawatts (MW).

Energy Consumption/Load
The use of energy as a source of heat or power or as a raw material input to a manufacturing process.

Demand Charge
That portion of the consumer's bill for electric service based on the consumer's maximum electric capacity usage and calculated based on the billing demand charges under the applicable rate schedule.

Energy Charge
The portion of the charge for electric service based upon the electric energy (kWh) consumed or billed.

Capacity
The maximum amount of electrical power that a system or facility can produce or deliver at a given time, often used to determine charges based on peak usage demand.

Peak Load Contribution (PLC) /Capacity Tag
A measure of an electricity customer’s specific demand (measured in kilowatts, kW) during the highest demand hours (peak hours) on the electrical grid.

Transmission
One core stage of the electrical grid that delivers electricity from power plants to consumers.
Transmission moves high-voltage electricity from power plants to substations.

Network Service Peak Load (NSPL) /Transmission Tag
A demand-based value assigned to a customer's electricity meter that determines their share of the costs for using a high-voltage transmission grid. The NSPL is typically calculated based on a customer's demand during the highest peak hours of the transmission owner's zone, which can occur during both summer and winter seasons.

Losses / Distribution Network Losses
The difference between the electrical energy entering the distribution network and that exiting the network.

Ancillaries / Ancillary Services
Services that ensure reliability and support the transmission of electricity from generation sites to customer loads. Such services may include load regulation, spinning reserve, non-spinning reserve, replacement reserve, and voltage support.

Coincidental Peak Demand / Load
The sum of two or more peak loads that occur in the same time interval.

On/Off Peak Demand
On-peak and off-peak demand refer to the fluctuation in electricity usage throughout the day, which utility companies use to structure rates, encourage efficiency, and manage strain on the electrical grid. These periods are characterized by when electricity demand is at its highest (on-peak) or lowest (off-peak).

Peak Load
The highest electrical demand within a particular period of time.

Load profile (or usage profile)
A graph or data set illustrating the variation in electricity consumption (measured in kW or kWh) over a specific time, such as a day, week, or season.

Load Factor
The ratio of the average load to peak load during a specified time interval.

Curtailment
The temporary, intentional reduction of power production (generation curtailment) or power consumption (load curtailment) when there is too much electricity in the grid (generation curtailment) or when there is not enough power in the grid (load curtailment). It acts as a necessary safety valve to balance supply and demand and prevent blackouts.

Peak Load Management
The process of reducing energy consumption during periods of peak system load. This can lower costs, enhance grid reliability, and reduce emissions.

Demand response
The actions a business takes when enrolled in an incentive-based program that encourages electric power customers to temporarily reduce their demand for power at certain times in exchange for lower electricity bills.

Energy Efficiency
A ratio of service provided to energy input. Unlike conservation, which involves some reduction of service, energy efficiency provides energy reductions without sacrifice of service. May also refer to the use of technology to reduce the energy needed for a given purpose or service.

Sustainability jargon

Net-Zero
Refers to balancing the amount of greenhouse gases produced with the amount removed from the atmosphere, aiming for a net result of zero emissions.

Carbon Neutral
What a company or organization achieves when the amount of CO2 they have emitted into the atmosphere has been removed or mitigated through carbon offset projects or technologies that capture and store carbon.

Carbon Credits
A way to offset carbon emissions by assigning a monetary value to the amount of carbon dioxide (CO2) or its equivalent in other greenhouse gasses that businesses or organizations emit.

Carbon Offsets
Tradable certificates linked to renewable energy, reforestation, agriculture, and community projects which reduce or remove CO2 emissions. A single certificate is equivalent to a reduction of one metric ton of carbon dioxide emissions. By purchasing a carbon offset, an organization is paying for a reduction in emissions equivalent to the amount it is attempting to offset. The funds raised through carbon offsets is channeled to sustainability projects around the world.

Decarbonization
Refers to lowering the amount of CO2 created from human activity and released into the atmosphere.

Scope 1 Emissions
Greenhouse gas emissions from sources owned or controlled by an organization. Examples include: vehicles, equipment, or facilities that use fuel or natural gas.

Scope 2 Emissions

Scope 3 Emissions
Greenhouse gas emissions caused indirectly by an organization’s supply chain and vendors related to the organization’s activities. Examples include: transmission and distribution, business travel, supply chain, employee commuting, and contracted solid waste or wastewater.

Renewable Energy Certificate (REC)
A market-based instrument that represents the property rights to the environmental, social, and other non-power attributes of renewable electricity generation. RECs are issued when one megawatt-hour (MWh) of electricity is generated and delivered to the electricity grid from a renewable energy resource.

Energy Attribute Certificates (EAC)
Internationally recognized certificates that prove that electricity has been generated from solar, wind, or another renewable source. They can help businesses reduce Scope 2 emissions and meet sustainability goals.

PPA (Power Purchase Agreement)
A long-term contract (typically 10-15 years) through which a corporate buyer agrees to purchase electricity and Energy Attribute Certificates (EACs) physically or virtually from a renewable energy generator.

Virtual PPA (VPPA)
A financial arrangement between a renewable energy generator and a corporate buyer to obtain renewable electricity, along with associated Energy Attribute Certificates (EACs).

ESG (Environmental, Social, Governance)
Refers to a set of standards used to measure an organization’s environmental and social impact. A framework used to measure a company's sustainability, ethical impact, and operational risk beyond financial performance. It examines three key pillars: Environmental (stewardship of nature), Social (relationship management with employees, customers, etc.), and Governance (leadership and operations).

Sustainability Reporting
The public disclosure of a company's environmental efforts specifically focusing on decarbonization, carbon emissions (Scopes 1, 2, and 3), resource management, and energy transition strategies.

Compliance Market
A mandatory, government-regulated system (often cap-and-trade) that forces high-emission entities—such as power plants and heavy industries—to pay for their greenhouse gas emissions. These markets set a cap on emissions with stiff penalties for non-compliance.

Voluntary Market
Refers to companies and organizations that choose to offset emissions voluntarily, usually because they are motivated by corporate social responsibility and sustainability goals.

Environmental Attributes
Refers to the characteristics or features of a product, service, or process that have an impact on the environment. They typically include any and all credits, benefits, emissions reductions, offsets, and allowances associated with the generation or production of power or fuel. They are often certified through mechanisms like Renewable Energy Certificates (RECs).

Market jargon

Letter of Authorization (LOA)
A legally binding document between a business and an energy broker that grants permission to access data and act on behalf of the client (non-exclusive). Many suppliers require an LOA before they will release their prices to a broker.

Letter of Exclusivity (LOE)
A legally binding document between a business and an energy broker, consultant, or supplier, granting that specific party the sole (exclusive) right to negotiate or manage the business's energy procurement for a defined period.

Electric Distribution Company (EDC)
The company that owns the power lines and equipment necessary to deliver purchased electricity to the customer. They ensure services are reliable and monitor customer usage via metering systems.

Local Distribution Company (LDC)
Similar to EDC, LDC is the utility company that manages the infrastructure for transporting
energy to a specific geography. However, it is commonly used for natural gas delivery.

Utility Company
A regulated entity responsible for generating, transmitting, and distributing energy (typically electricity or natural gas) to the public.

Hedging
The buying and selling of futures contracts so as to protect energy traders from unexpected or adverse price fluctuations.

Forward Curve
A forward curve is a graphical representation showing the market-quoted prices for commodities for delivery at specific future dates. It reflects market expectations of future prices and is constructed using data from futures contracts, swaps, or other derivatives.

Locational Marginal Price (LMP)
The price for electricity that reflects the incremental cost to increase electricity generation to satisfy electricity demand at a specific location—node, load zone, reliability region, or hub. LMPs may have multiple components, such as charges for energy, congestion, transmission system losses, and carbon charges. Both day-ahead and real-time LMPs exist. Real-time LMPs can be set for hourly or sub-hourly blocks. Regional transmission organizations and independent system operators use LMPs to help establish price signals to meet electricity demand.

Day-Ahead Market
Forward markets where electricity quantities and market clearing prices are calculated individually for each hour of the day on the basis of participant bids for energy sales and purchases.

Real-Time Market
An electricity market that determines the price for one-hour periods or less during the day of delivery.

Daily Gas Market
Also known as spot market, a market in which natural gas is bought and sold for immediate or very near-term delivery, usually for a period of 30 days or less. The transaction does not imply a continuing arrangement between the buyer and the seller.

Henry Hub
A pipeline hub on the Louisiana Gulf coast. It is the delivery point for the natural gas futures contract on the New York Mercantile Exchange (NYMEX).

New York Mercantile Exchange (NYMEX)
One of the world’s largest commodity futures exchanges, facilitating trading in a wide range of commodities, including energy products, precious metals, and agricultural commodities.

Basis
The differential between a spot or “cash” price and the nearest equivalent futures price. Basis is normally quoted as cash minus futures price. A positive number indicates a futures discount; a negative number indicates a futures premium.

Contract Swing
A contract for the purchase of oil, natural gas, or electricity that includes an option to adjust the volume of energy purchased and the price paid within predetermined limits. Also known as “take-and-pay options” or “variable base-load factor contracts,” the contract outlines the least and most energy an option holder can buy (or "take") per day and per month, how much that energy will cost (known as its strike price), and how many times during the month the option holder can change or "swing" the daily quantity of energy purchased.

Burner Tip Pricing
Burner Tip is the final destination where natural gas will be used. A burner tip rate includes an additional, built-in charge to compensate for lost and unaccounted-for gas (LUAF).

City Gate Pricing
City Gate is the physical point where natural gas is delivered to a local utility. City Gate pricing will include a fee to compensate for lost and unaccounted-for gas (LUAF) that happens as it travels through the pipeline.

Nomination

Balancing
Refers to the real-time process Transmission System Operators use to match electricity supply (generation) with demand (consumption) to maintain grid stability and a constant frequency.

Firm Service
Also known as uninterruptible service, it refers to a guaranteed electricity transmission, natural gas pipeline capacity, or fuel supply. It ensures delivery under almost all conditions and is often reserved for high-end users.

Interruptible Service
A contract arrangement where commercial or industrial customers agree to have their electricity or natural gas supply reduced or cut off by the utility during peak demand or supply shortage in exchange for lower, discounted rates.

Fixed Price
The price paid per kilowatt-hour (kWh) stays the same throughout the contract even if market prices increase or decrease.

Index Price
A method of determining the cost of energy based on a specific market index. It typically involves adding supplier charges to the current market index value. Unlike fixed-rate contracts, index pricing allows for real-time adjustments based on market changes.

Block and Index Price
A hybrid energy procurement strategy in which a set portion of energy load is purchased at a fixed price (block), while the remainder fluctuates with the market (index).

Load Following Block and Index Price
A hybrid energy procurement strategy in which a set portion of energy load is purchased at a fixed price and the supplier offers the ability to place hedges based on percentages of expected load (e.g. 25% of January’s load, rather than a 1.5MW block).

Delivery/Distribution Charges
The fees charged by local utility companies (often referred to as Transmission and Distribution Service Providers or TDSPs/TDUs) to transport electricity or natural gas from transmission networks to a home or business. Unlike supply charges, which fluctuate based on the cost of generating power, delivery charges primarily cover the costs of operating and maintaining the physical infrastructure of the power grid.

Energy Charges
A portion of your total charge for electricity service; the total number of kilowatt-hours consumed within the billing cycle times the price you pay per kWh.

Supply Charges
The price of electricity or natural gas offered by a supplier.

Generation Charges
The charge for producing electricity. If you purchase electricity from a supplier, your generation charge will depend on the contract between you and your supplier.

Billed Demand
The peak rate of electricity usage during a specific interval, typically 15–60 minutes, within a billing cycle.

Dual Billing
A method of billing in which one bill is sent by the supplier for the generation of energy, and a separate bill is sent by the EDC for distribution and other charges.

Utility Consolidated Billing (UCB)
In a market with Utility Consolidated Billing (UCB), the utility offers an option to retail suppliers in which it provides, for a fee, a single bill to the customer that includes both the utility’s delivery charges and the retail supplier’s supply charges.

Summary Billing
A service that consolidates multiple, separate utility accounts or service locations into a single monthly invoice with one total amount due and one due date.

Balancing Charges
Financial penalties or costs incurred when the actual amount of electricity produced or consumed by a generator or supplier deviates from their scheduled or forecasted amount.

Infrastructure & Technology jargon

Power Grid / Electric Power Grid
A system of synchronized power providers and consumers connected by transmission and distribution lines and operated by one or more control centers. In the continental United States, the electric power grid consists of three systems the Eastern Interconnect, the Western Interconnect, and the Texas Interconnect. In Alaska and Hawaii, several systems encompass areas smaller than the State (e.g., the interconnect serving Anchorage, Fairbanks, and the Kenai Peninsula; individual islands).

Smart Meter
A type of electricity meter that has continuously available, remote, two-way communication and information storage capability. Smart meters record and store electrical usage in 15-minute intervals and communicate that usage back to the local wires company. Unlike traditional electric meters that only measure total consumption, smart meters show when the energy was consumed.

AMI (Advanced Metering Infrastructure)
A system enabling two-way communication between meters and utilities. The system collects, stores, analyses, and presents energy usage data, providing utility companies the ability to monitor electricity, gas, and water usage in real time.

Distributed Energy Resources (DER)
Small-scale, decentralized electricity generation and storage technologies—such as rooftop solar, batteries, and electric vehicles—that work by first delivering energy directly to a facility or community, and then contributing excess energy into the main power grid. They can operate parallel to the utility grid or as stand-alone, off-grid systems.

Microgrid
A localized, small-scale power grid containing distributed energy resources (like solar, storage, or generators) and loads that can operate either connected to the main utility grid or independently. Often used with battery energy storage systems (BESS).

Battery Storage/ Battery Energy Storage Systems (BESS)
Devices that enable energy from renewables, like solar and wind, to be stored and then released when the power is needed most, usually during peak demand times.

Regulation jargon

Customer Choice Program
A program available in deregulated markets that allows businesses to select their electricity or natural gas supplier instead of buying directly from the local utility.

Competitive Energy Supplier/ Third Party Supplier/ Retail Energy Provider (REP)
A company operating in deregulated energy markets that purchases electricity or natural gas on the wholesale market and sells it directly to residential, commercial, and industrial consumers.

Retail Choice
Refers to the ability of consumers to select their electricity suppliers in a competitive market, rather than being limited to a default service provided by a utility.

Federal Energy Regulatory Commission (FERC)
An independent agency that regulates the interstate transmission of natural gas, oil, and electricity. FERC also regulates natural gas and hydropower projects.

Environmental Protection Agency (EPA)
A federal agency dedicated to protecting human health and the environment.

Independent System Operator / Regional Transmission Organization (ISO/RTO)
An entity that manages the flow of electricity across large regions. They balance supply and demand in real time and ensure grid reliability.

Broker/Energy Broker
Acts as an intermediary between consumers and energy suppliers; they work to find the best rates for their commercial and industrial customers.

Utility Tariff
A published and legally binding document that lists rate schedules and general terms and conditions under which a utility company provides electricity or natural gas to customers.

Utility
A regulated entity responsible for generating, transmitting, and distributing energy (typically electricity or natural gas) to the public.
