A unique number for the utility being provided. This stays constant for the supply whereas the Meter Number and Account Number may change.  Electricity is

MPAN (Meter Point

Administration Number), Gas is MPRN (Meter Point Reference Number) and Water is SPID (Supply Point Identifier).

Asset Type

An optional Item that represents an area within a Site that can be separately metered, for example:

• An Apartment within an Apartment Block
• A selection of Shopping Units within a Shopping Centre
• A group of solar panels

A Building Unit contains all Meters, Sub Meters, Virtual Meters and Supply Points that are related to it.

Resides under a meter or sub-meter database

Item.

An Item that represents a Time Series Data holder and is used to record and manage Consumption or Meter Readings data.
A High Frequency Data (HFD) Channel can be either Periodic or Non-Periodic:

• Non-Periodic – Used where Consumption or Meter Readings data is entered along with the datetime for which the data is applicable.
• Periodic – Used where measurement of Consumption or Meter Readings data is performed on a routine recurring periodic basis.

A utility, the usual ones you would expect are Electricity, Water, Gas and there are other more obscure such as Wood pellets, Oil and Paper waste.

A referenceable agreement between you and the Provider. A Contract may be evergreen in which case the Permanent option is selected, or it may be

time-bound, having both a start date and an end date.

A Contract is for a single commodity type and may cover one or more supply points and their meters.

The intermediary object used to relate Contracts, Accounts, Supply Points and Meters. A Contract Container defines, for a period of time, the Contract that is applicable for the provision of a utility through the Meters on a Supply Point that is billed via an Account.

Specifies the rate of charge per unit of the commodity consumed.  You can have different cost definitions for different periods of time.  It has as a From and To date.

A Cost Definition can be used in Widgets to calculate costs and display the results. The feature is useful when you have meter readings or consumption data but have not yet received the supplier bill. Sigma can then base its data on the information loaded and produce an early indication of costs rather than waiting for the bill to arrive.

There are three flags that show in Billing A, R and L:

A & R Flags – these are flagged against a bill to say that it should be included in reporting.  If they are unticked, the Bill will be excluded from the reporting.

L Flag – this is the Accounts Link Flag.  If ticked, it means that that bill is eligible to be included in the Accounts Link File.

The Invoice Number is found on the Invoice (bill) and is unique.  This will be entered into Sigma to identify the Invoice (Bill).

The equipment that measures and records the flow of a utility through a Supply Point during a period of time. The provision of utilities is often measured based on recording the amount consumed directly or recording readings of how much has flowed through the Meter at two separate times and then inferring that the amount consumed is the difference between the readings.

The creation of Meters is required if you wish to use Sigma for Monitoring and Targeting purposes.

As Meters represent the technical physical reality there is no need for any decision making with regards to the level and number of these that need to be created. Distinct Meters need to be created for each Meter from which you anticipate receiving data which needs to be loaded into Sigma.

Meter number in Black – Energised

Meter number in Red – De-energised

The number given by the Provider and seen on the Invoice (Bill).  Used to identify the Account to which we need to add bills to.

A Monitoring Point stores information that has been created from various sources of data. For example, a calculation of the total gas consumed by a number of sites derived from gas consumption data at each individual site. The data in the Monitoring Point object would be generated by an equation (in this case a simple sum) combining all of the sources of data (in this example gas consumption at each site)

Channels are the time series data holders that are used in Sigma to record and manage data. Similar to Meters, and their use of readings or consumption, Channels come in two types; Non-Periodic and Periodic.

A Non-Periodic Channel is a channel for which consumption or reading data is entered along with the

date-time for which they are applicable.

A Non-Periodic Channel is required in order to be able to use Sigma to Enter Meter Readings.

The top-level entity with respect to the portfolio’s physical structure. An Organisation may be created for each legal entity that is billed and responsible for the consumption of utilities, or a single Organisation may be created for an entire group. In most cases a single Organisation is used to manage a customer’s portfolio.

The decision with regards to the number of Organisations

 that you wish to create largely comes down to the need to differentiate the assets attributable to each. If there is a strong need to separate information then it would be sensible to have separate Organisations (for example if there is a need to attribute inbound and outbound costs to different legal entities), however, if the combined picture is more often of interest then a single Organisation is likely to achieve the desired results.

Used to record data for cases where the measurement of consumption is performed on a routine recurring periodic basis.

Method by which it is possible to assign custom data to the entities in your Utility Portfolio. These custom properties can then be used to search for records in your portfolio.

The legal entity that supplies you with services or a utility for which you expect to be charged. A single Provider may supply you with more than one utility (e.g. Electricity and Gas). Within Sigma there are three main types of Provider which are; Supplier, Meter Operator or Data Collector and Aggregator. A single Provider may fulfil any one or more of these services.

Your Site may have sub-meters, for example you may have one large Site where you have one main Meter and want to monitor the particular usage in a section of the Site such as a kitchen.

In Sigma Sub-Meters work the same as Meters but allow you to categorise them differently. You can also store the sub-meter data, its serial number and so on.

Represent the industries’ physical infrastructure required for the provision of a utility of a given commodity to your Site. In the case of utilities that aren’t supplied continuously (e.g. Oil Deliveries), the Supply Point represents the storage facility on-site.

The Supply Point in Sigma is the Item that links the different parts of the story (physical, technical and supply) together.

The provision of a utility through a Supply Point is normally technically measured using Meters, that may record readings/consumption based on differing frequencies.

The quantity of the utility, or its availability for use if required, (the supply) is billed to the customer based on their contractual agreement with their Providers.

Supply Points are the entities that provide visibility of the Contract Containers that link these different aspects together for defined periods of time.

Example Supply Points:

• Electricity: Meter Point Administration Number (MPAN)
• Gas: Meter Point Reference Number (MPRN)
• Water: Supply Point Identification Number (SPID).

Defines a relationship for an effective period of time between a Provider Contract, a Account and one or more Meters, Sub Meters, Virtual Meters.

A TSP is an Item that produces time series data, for example:

• A Periodic HFD Channel produces consumption data
• An Account produces Supplier Bill data
• A Monitoring Point
