Clearinghouse

  • What is the Upstream Capacity Clearinghouse

    Southern direct purchase customers may seek an alternate upstream capacity allocation by finding a Southern counterparty willing to make equal and offsetting changes to their upstream capacity allocation components. Union Gas put a transportation clearinghouse in place (the Upstream Capacity Clearinghouse on Unionline) as one mechanism through which customers in the South could voluntarily rearrange their transportation allocations/assignments among themselves.

    Union Gas will act as the website manager in the Upstream Capacity Clearinghouse and will be responsible for posting information only. Union Gas will not be a party to any negotiations between customers and will not act as an arbitrator if an agreement cannot be reached.  There is no charge for the use of the Upstream Capacity Clearinghouse

Measurements

  • How is Energy calculated?

    On measurement pages, we provide both volumetric consumption as well as the equivalent heat energy. For sites specially equipped with gas sampling equipment, average monthly heat values are gathered and used as the basis for conversion to energy. These energy conversion factors are applied on a posted basis.  For gas sampled in month one, we apply the conversion to volumes in month three. This lag time is required to collect gas samples and have them analyzed in an independent laboratory. Posted heat values are usually made available approximately three days prior to the start of the month for which the values will apply.

    For sites that have no gas sampling equipment, we use a System Wide Average Heat Value (SWAHV). This average value is based on measurements taken at Union's interconnects and can change annually.

    The calculation for heat value is:

    Heat Value (Gigajoules) = Consumption (m3) * Sampled Heat Factor (MJ/m3) / 1000

  • What are "Degree Days"?

    Degree days are calculated by taking the difference between 18oC and the average Gas Day temperature. An average temperature under 18oC results in heating degree days, while an average over 18oC results in cooling degree days. Average daily temperatures are based on your location's proximity to one of the following weather stations:

     

    Earlton, Ontario

    Ottawa, Ontario

    Hamilton, Ontario

    Sarnia, Ontario

    International Falls, Ontario

    Sault Ste Marie, Ontario

    Kapuskasing, Ontario

  • Where does the Heat Value come from?

    A South System Wide Average Heating Value (SWAHV) is effective at all southern area interconnects and is updated twice a year - November 1 and April 1. For the Northern Delivery Areas, there is a Heating Value for each zone and this is updated monthly. This value can be used to convert volumes to energy and vice versa. The term "heating value" is in reference to the amount of megajoules per cubic meter (MJ/m3) produced by the complete combustion at constant pressure of one cubic meter of gas (@ 101.325 KPA and 15oC) with the gas free of water vapour and the temperature of the gas, air and products of combustion to be at standard temperature and all water formed by the combustion reaction to be condensed to the liquid state

Measurements - Distribution

  • How do I determine which meter description refers to which physical meter?

    We have done our best to try to describe each meter based on the information we have. However, in some cases, it may not be clear which physical meter is associated with those described in Measurement Search. If you display measurement results at the meter level, you will be able to see the currently assigned meter number. This number is engraved on the physical meter. If you wish to change the description of the meter that appears on the Measurement Search page, contact Unionline Support and let us know which meter to change and the description you prefer.

  • What does the message Heat values missing-using SWAHV mean

    For sites specially equipped with gas sampling equipment, we use the sampled value to determine energy consumption. In the event we are expecting to have gas sampler data and we don't, we will temporarily use the System Wide Average Heat Value (SWAHV). Once the gas sampler data is made available, the energy consumption data will be corrected to reflect the new conversion factor. Back to Top
  • What is a "Gas Day"?

    The measurement gas day is defined as the consecutive 24 hour period between 10:00 am and 10:00 am Central Standard Time. The measurement gas day does not change as a result of Daylight Savings Time. Back to Top
  • What is Average Energy Consumption on a distribution contract’s measurement?

    The average energy consumption values provide the simple average energy consumption over the past one, three, and ten days in which complete measurement data is available. For example, if one of three meters did not register consumption data yesterday, the previous day is considered the start of the averages. Back to Top
  • What is "Peak Hour"?

    Peak hour information is shown on the measurement results screen for each telemetered meter. The peak hour volume is the volume of gas that flowed during the hour during the Gas Day that recorded the maximum hourly consumption. The peak hour represents the start of the hour in which that consumption occurred, and represents the hour of the Gas Day in which the peak occurred. For example, a peak hour of 08 on Gas Day December 15 actually occurred on calendar day December 16 for the gas burned between 8:00 am and 9:00 am. Back to Top
  • What is the unit of measure for metered data?

  • What is Parkway Callback?

    Unbundled contracts have the ability to deliver gas into Union Gas' system at varied receipt points (Parkway, Dawn, Dawn Vector, etc.) based on their entitlements. This means that a contract holder could deliver all of their DCQ at points other than Parkway. These deliveries are non-obligated.

    From November to March, during periods of peak demand, Union has the ability to "callback" a contract's Parkway DCQ, up to a maximum of 22 days. If Union were to "callback" Parkway volumes a customer would be required to bring in a specified DCQ at Parkway on an obligated basis.

  • Will future dated transactions appear in the DP Status Report?

    The DP Status Report is part of the monthly DP invoice and therefore is updated once a month. It is a snap shot in time, and does not change during the month with activity. Any future- dated balancing transactions that are approved prior to the monthly invoice completion, will be calculated into the Projected Banked Gas Account balance. This gives you a more accurate projection of where your Banked Gas Account balance will be at the next balancing point in the Contract.
