Services to ensure the reliability and safety of the electricity supply system.
Average Rate Option cap
Is an automatically exercised product where the payout is determined based on a specified averaging period. The payoff is calculated on a specified averaging period that places a ceiling on the price the customer pays for electricity. The difference between an Average Rate cap and a standard cap is that the payouts are based on average prices across the contract period rather than each interval. The longer the period the lower the premium because the protection is against average prices rather than single price events.
It places a ceiling on your power price protecting you against a possible increase in market price, while allowing you to take full advantage of a lower market outcome should it occur. This is different to a swap where in the event of the lower market outcome you would still pay the swap contract value.
A base load generator provides power at a more-or-less constant output level to the electricity system outside of temporary shut down for maintenance. These generators take a long time to start up but are relatively cost effective to run.
Caps are automatically exercised half-hourly call options. They activate when the spot price goes over the strike price – normally $300/MWh. A premium is paid during the period when the cap is activated. By securing a Cap you can ensure you won’t pay over the $300/MWh price if an event occurs.
Is an option to enter a cap in the future at a predetermined premium and fixed price. Where swaptions provide the right, but not the obligation to buy or sell a swap, a caption provides the same right to buy or sell a cap at a predetermined price when exercised.
Captions give the customer the ability to protect against possibly higher future prices while allowing you take advantage of a low price should it eventuate.
Gives you access to the lows of the market while putting a roof over your price. This means we set a maximum average price you’ll pay in the quarter ensuring you never pay more.
Refers to a situation where customers are legally entitled to choose their energy retailer. Across Victoria, Tasmania, NSW, SA and southern Queensland, most customers can choose their electricity retailer.
Contract for difference
A financial hedging arrangement on the wholesale market, where two parties agree to trade a certain volume of a product for a set price. This is the same as what happens in the financial markets but with energy trading.
The product is purchased in a separate ‘physical market’ (e.g. wholesale electricity market). If the price is higher or lower than the agreed price, then the parties settle the difference between the ‘hedge contract’ and ‘physical market’ prices.
Contract maximum demand
The maximum level of demand specified in a network connection agreement or energy supply contract, for which a distribution network service provider will levy a charge.
The network sets a maximum amount of energy that a customer can draw from the grid at any one point. If the customer exceeds this point then the customer is put on a higher tariff. Flow Power works with businesses to install the controller to manage this demand as it often happens over a short period of time, usually around 10 minutes.
The charge is linked to an increment of network system capacity or load (demand). Penalties may apply should the end user exceed this maximum demand, and the distribution network service provider may increase the contract maximum demand for a forthcoming period of up to 12 months.
An approach that seeks to align prices with an estimate of actual costs to deliver power to a customer at that point in time rather than aggregated across the system. That means power delivery costs to regional areas can be more expensive than in cities because there is less volume. However, power to homes situated near a power station can be delivered cheaper because of the less distance it needs to travel.
Customer load variation charge
When retailers provide customers with a fixed rate, they need to project the total amount of power that customer is going to use. That means they can secure contracts in the ASX Futures market or allow for the energy in their wholesale strategy. Therefore when a customer’s energy use varies significantly, it can have major impact on a retailer’s profitability. This isn’t an issue for Flow Power customers because you have control and flexibility over how your power is bought.
A mechanism where end users can benefit by changing their use in response to real-time electricity prices or short-term network constraints. Depending on how end users set up their demand-side response, it can provide them with additional revenue or a saving on their electricity bill that is substantially more than the cost of providing demand-side response. For wholesale electricity customers, this occurs automatically as they respond to the market signals. The result is a much more efficient working market.
The price for electricity in a wholesale electricity market that is necessary to provide the energy capacity needed to match demand in a five-minute ‘dispatch period’. This is the price that the generators are being paid for the set five minutes.
This refers to the poles and wires of the electricity delivery system – the low voltage movement of energy. Distribution networks take power from the transmission networks to homes and businesses across Australia. Sometimes businesses will operate both transmission and distribution networks. There are many distributors across the National Electricity Market:
- NSW: Ausgrid, Essential Energy and Endeavor Energy
- SA: SA Power Networks
- VIC: Powercor, United Energy, Citipower and Jemena
- QLD: Ergon Energy and Energex
- ACT: ActewAGL
Electricity futures contract
A standardised exchange-based contract for difference that specifies the price and quantity of electricity that will be traded at a specified point in the future. These contracts are used to hedge financial risk rather than physically trade power. They are bought and sold on the ASX Futures market and can help you understand the future costs of energy. See also Contracts for Difference.
The bulk transport of electricity through extra high voltage power lines. These lines take power from large scale electricity generators to distribution networks. Then the distribution networks transport low voltage power to homes and businesses. Transmission accounts for approximately 10% of the average electricity bill however this differs from state to state.
An electricity network, not owned by an electricity distributor, that is part of a multi-tenanted or strata titled building. The local distributor has an obligation to install meters that allow individual tenants and/or owners to select their own energy retailer and assign a network tariff to each meter. Where feasible, a single end-user can arrange for the individual meters to be consolidated to a single metering point within the building, thereby benefiting from lower network tariff costs than would apply to all the individual meters.
Freedom (Flow Power power plan)
Freedom is an energy plan that gives businesses the flexibility to reduce load or transfer to an onsite generator when prices rise. It gives businesses direct access to the wholesale market price, and puts them in complete control of energy costs. Flow Power keeps a close eye on wholesale market activity on a business’ behalf and shares expert predictions. Freedom also comes with SMS and email alerts backed by 24/7 online and telephone support.
A generic term for entities that own and operate major electricity generating facilities and are active in the retail market. Examples include AGL, Energy Australia and Origin Energy.
Gross pool market
An electricity trading arrangement used in the National Electricity Market where generators are required to sell the energy they produce. A gross pool market differs from a net pool market where generators only sell energy that they have not already sold through bilateral contracts. See also Net Pool Market.
Just like fixing sections of your home loan, you can look at different hedges for your electricity. Such as, ceilings or CAPS to manage the price you are paying for power.
Inter-regional loss factor
A factor applied to electricity transported between National Electricity Market regions that accounts for the energy loss incurred when transporting electricity between two regions’ Regional Reference Nodes (RRNs). See also Regional Reference Node (RRN) and Loss factors.
Entities that offer a range of services to end users such as providing information and advice on energy use and procurement, supporting negotiations with retailers, and facilitating demand-side response measures. This includes energy brokers and metering providers. Often they will bundle services into ongoing electricity contracts.
Forms of generation that cannot control when they supply energy into the electricity grid. Intermittent generation include wind power, solar power, and wave and tidal power. Often these sources are inexpensive to operate. Intermittent generators can only supply energy into the electricity grid when their primary energy source (i.e. wind, sun, wave or tide) is available. See also Base load generation.
The kilovolt-ampere (kVA) unit refers to components of electrical energy which are metered separately to take account of variations in Power Factor between individual connection points. One kVA will be precisely equal to one kilowatt (kW) when the Power Factor is 1.0. End users get less usable energy (kW) than they pay for if the Power Factor is higher or lower than 1.0.

Large-scale generation certificates
Certificates created under the Large-scale Renewable Energy Target (LRET) scheme in the online REC Registry administered by the Office of the Renewable Energy Regulator (ORER) by renewable energy power stations. One LGC is equivalent to 1 MWh (megawatt hour) of eligible renewable electricity generated above the power station’s baseline. End users may be able to benefit from creation of LGCs (e.g. if they operate an eligible biomass cogeneration facility). See also Small-scale technology certificates.
Large-scale renewable energy target scheme (LRET)
An Australian government scheme designed to increase the proportion of energy produced by prescribed large-scale renewable energy technologies. The LRET places an obligation on liable parties (wholesale purchasers of electricity – primarily, energy retailers) to source a specified proportion of their energy purchases from large-scale renewable energy generators each year. See also Large-scale generation certificates and Small-scale technology certificates.
Liquefied natural gas
Natural gas that has been converted into liquid form making it more cost-effective to store and transport.
Refers to how an individual end user’s electricity demand changes throughout the day and year. The load profile is one of the main factors that determines what retailers will charge end users for their electricity supply. All else being equal, the more variable and less predictable the load profile, the more fixed rate electricity retailers will charge end users for energy supply. This doesn’t happen with customers who buy wholesale because they are buying exactly what they need. See also Customer Load Variation Charge and ‘Peakiness’ of demand.
A form of demand-side response where an energy user can shift energy consumption from one time of day (or week) to another. Wholesale customers can benefit from this when power prices drop because they are paying the market price. At times when the price goes into the negative – Flow Power customers can be paid to use power. See also Demand-side response.
Load weighted average
A method for calculating an average market price that weights the price in each trading period by the level of demand or volume for that period. This is the price that Flow Power customers pay for their power. It helps customers control their energy costs over time. See also Time Weighted Average.
An amount included in power bills to account for losses that occur in transmission and distribution lines as electricity flows from generators to end users’ sites. These losses have a financial effect on energy retailers because they buy ‘wholesale’ electricity as it enters the transmission system at generator connection points but can only sell the ‘retail’ electricity that is delivered to end users; and the volume delivered is reduced by the losses. Wholesale electricity market rules allow energy retailers to recover the cost of these losses from energy users.
A party that purchases electricity directly from the wholesale market – such as Flow Power. Flow Power enables businesses who use more than 160MWh of power to become market customers.
The concepts determining the rules that govern how a product is traded.
An electricity generator that participates directly in the wholesale market. For each trading period, market generators submit offers for the volume of energy they are willing to supply at specified prices. All grid-connected generators with a nameplate rating of 30MW or more are required to register as market generators.

Market price cap
The highest wholesale market price allowed for wholesale market bids or offers. The wholesale market price cannot be greater than the price cap. At the moment, this is set at $14/kWh. See also Market price floor.
Market price floor
The lowest wholesale market price allowed for wholesale market bids and offers. The wholesale market price cannot be lower than the price floor. The price floor can be negative and go to $-1/kWh. See also Market price cap.
Mastery (Flow Power power plan)
Mastery gives businesses certainty in energy by opening access to the wholesale market. Businesses get direct access to the wholesale market price – without the risk of being charged above a set ‘ceiling’ for that quarter. You get access to the floor market price, which can be as low as -$1kWh. If a site is larger than 5GWh, Flow Power looks at a business’ usage profile to tailor Mastery with extra tools to help the business get even more out of the wholesale market.

Options are an actively traded financial product in the NEM managing forward price risk. They give a customer the option to enter a derivative on a future date and at a predetermined fixed price.
Payback period (in yrs) =
Includes both energy and non-energy quantifiable costs and benefits. No discounting of future costs and benefits is done when calculating a simple payback period.
The maximum demand on the electricity system at any time during the year. The underlying cost of supplying electricity, and the wholesale market energy price, is typically the highest at peak periods because system reliability requires the dispatch of high cost flexible ‘peaking’ generation such as Open Cycle Gas Turbine (OCGT) and because electricity transmission and distribution networks must be built to withstand peak demand. The price that end users pay for energy is indirectly affected by peak demand, because ‘market sentiment’ engendered by high wholesale market prices may affect the contract price that a retailer is prepared to offer or accept. Flow Power customers can manage the system peak demand by reacting to market signals as they normally would. This helps manage costs throughout the year as well as during the times of the peak demand.
The highest level of demand within a specified period.
A form of demand-side response where an energy user can reduce energy consumption (and demand) during peak periods. Flow Power customers actively peak shave by reaction to the wholesale market signals. We let customers know about peaks through our . See also Demand-side response and Load shifting.
Peakiness of demand
An expression that refers to a particular characteristic of a load profile, which is considered ‘peaky’ if it is particularly variable or volatile. All else being equal, retailers will charge individual end users more for peaky demand. See also Load profile.
Petajoule (1015 Joules).
Price duration curve
A curve that shows the distribution of trading interval wholesale energy prices over a year in descending order.
Price efficiency factor
All customers who choose Flow Power’s Ceiling Price Power Tool are given a price efficiency factor. This factor is a ratio that represents how they are maximizing the market. Based on whether they use power during the highs or lows of the market, we calculate a ratio against the average price in the market. So if they take advantage of the lows of the market and ramp up during those times, their price efficiency factor will be low, but if they happen to be using power during peaks it may rise.
For customers, the price efficiency factor gives them a simple picture of how they are tracking against the wholesale market and can be used to modify their ceiling price.
An indirect signal provided by a market price to existing generators and potential new entrants indicating that there may be value in providing additional capacity.
Regional Reference Nodes
A notional reference point in each region of the National Electricity Market where the Regional Reference Price is set for every half-hourly trading interval. Regional Reference Nodes are also used for calculating inter-regional loss factors, which are the loss incurred when transmitting electricity between two regions using regional interconnectors. See also Inter-Regional Loss Factors, Loss Factors and Regional Reference Price.
Regional Reference Price
The wholesale pool price for a particular half-hourly trading interval. See also Dispatch Price, Regional Reference Node and Spot Price.

Small-Scale Renewable Energy Scheme
An Australian Government scheme designed to increase the proportion of energy produced from prescribed small-scale renewable energy systems. The Small-Scale Renewable Energy Scheme places an obligation on liable parties (wholesale purchasers of electricity – primarily, energy retailers) to purchase a required amount of Small-Scale Technology Certificates from providers or owners of prescribed technologies each year.
Small-scale technology certificates
Certificates created under the Small-scale Renewable Energy Scheme in the online REC Registry administered by the Office of the Renewable Energy Regulator. Technologies covered include correctly installed eligible solar water heaters, heat pumps, and small-scale solar panels, wind, and hydro systems. End users may be able to benefit from creation of Small-scale technology certificates (e.g. if they install eligible technologies). One certificate is equivalent to 1 MWh (megawatt hour) of:
•renewable electricity generated by the solar panel, small-scale wind or small-scale hydro system (unless a Solar Credits multiplier applies); or
•electricity displaced by the installation of a solar water heater or heat pump.
See also Small-scale Renewable Energy Scheme.
