24th July, 2009

New BM Unit Data Items

The following items have been added to the BM Unit data tables.

  • RCRC - The "Residual Cashflow Reallocation Charge" is used to reallocate the moneys due to or from parties from energy imbalance settlement back out to participants. It is also more colloquially known as the beer-fund. The RCRC is calculated inside settlement to the energy account level. This new field is populated by NETA reports and recreates this calculation but at the BM unit level.
  • Generation Capacity - The generation capacity in MWs reported by BSC parties to Elexon and published by them on www.elexon.co.uk. This number is changed at least seasonally. It is also known by some as the name plate capacity.
  • Demand Capacity - The demand capacity in MWs reported by BSC parties to Elexon and published by them on www.elexon.co.uk. This number is changed at least seasonally.
  • CO2 - The tonnes of CO2 emitted by a power station when converting fuel to electricity.
  • SO2 - The tonnes of SO2 emitted by a power station when converting fuel to electricity. Currently a place holder whilst Environment Agency data is integrated into the system.
  • NOx - The tonnes of NOx emitted by a power station when converting fuel to electricity. Currently a place holder whilst Environment Agency data is integrated into the system.

New Derived BM Unit Data Items

The following items are now available as derived data items.

  • FPN + BOA + ABSV Volume - The FPN Volume plus the BOA Volume plus the applicable balancing services volume in MWHrs for the half-hourly period. The FPN + BOA + ABSV volume is at the GSP.
  • FPN Percentage of MEL - The notified volume (FPN) modified by balancing actions (BOA + ABSV) as a percentage proportion of the MEL. This is useful for determining the short term utilisation of plant from notification data. Only sensible for generation BM units.
  • FPN Percentage of GC - The notified volume (FPN) modified by balancing actions (BOA + ABSV) as a percentage proportion of the generation capacity. This is useful for determining the utilisation of plant from notification data. Only sensible for generation BM units.
  • Metered Volume Percentage of MEL - The metered volume as a percentage proportion of the MEL. This is useful for determining the short term utilisation of plant from metered data. Only sensible for generation BM units.
  • Metered Volume Percentage of GC - The metered volume as a percentage proportion of the generation capacity. This is useful for determining the utilisation of plant from metered data. Only sensible for generation BM units.
  • MEL Percentage of GC - The MEL volume as a percentage proportion of the generation capacity. This is useful for determining the short term availability of plant compared against its declared generation capacity. Only sensible for generation BM units.
  • MIL Percentage of DC - The MIL volume as a percentage proportion of the demand capacity. This is useful for determining the short term demand requirement compared against its declared demand capacity. Only sensible for demand BM units.

Impact of New Items on the System

The new items at BM Unit level have now appeared throughout the system on the various spreadsheets that contain BM Unit derived information. They will appear as new tabs in the spreadsheet. All cached spreadsheets that require these new fields have been set to stale. The new data items are also on the BM Unit data download page.

XML-REST Web Services

Users have always been able to download a number of data items via an XML-RPC backend interface. This interface however is quite difficult for ordinary users to use. A new XML-REST interface has been implemented which is more easy to use for ordinary users. Documentation for this service is available at the XML-REST section of the backend pages. Three services have been implemented:

19th May, 2009

NGC Fuel Type Summaries

Two new pages have been added to the fuel type summary section.

  • The settlement period fuel type data page is used to generate a spreadsheet with BM Units grouped by NGC fuel type to arrive at a settlement period total per fuel type for a time period. Data displayed is volumes and balancing mechanism acceptance volume, cash-flow and price data.
  • The daily NGC fuel type data page is used to generate a spreadsheet with BM Units grouped by NGC fuel type to arrive at a daily total per fuel type for a time period. Data displayed is volumes and balancing mechanism acceptance volume, cash-flow and price data.

Power Station Summaries

A new sub-section has been added to the summary section. The power station page displays information by power station. This section has two new pages.

  • The settlement period power station data page is used to generate a spreadsheet with BM Units grouped by power station to arrive at a settlement period total per power station for a time period. Data displayed is volumes and balancing mechanism acceptance volume, cash-flow and price data.
  • The daily power station data page is used to generate a spreadsheet with BM Units grouped by power station to arrive at a daily total per power station for a time period. Data displayed is volumes and balancing mechanism acceptance volume, cash-flow and price data.

28th April, 2009

Gas Fired Power Station Summary

The Gas Fired Power Station Summary page has been fixed. The problem was with the interface to the NGC gas data site but this has been fixed. Data is available from October 2007.

10th February, 2009

Large Combustion Plant Directive Spreadsheet

A new page has been added. The Large Combustion Plant Directive Spreadsheet page allows the user to download a summary of operating hours under the large combustion plant directive. It uses environment agency numbers with metered volumes and FPN volumes to predict operating hours and make an educated guess at the closure date of opted out plant.

As a consequence of this work the carbon spreadsheets have been moved to a new emissions section.

18th January, 2009

9th December, 2008

New variables on BM Unit Data Download

The BM Unit Bulk Data Download page has been modified to provide more information.

Information on available and declared bid offer pair volumes before acceptances has been summarised up to the settlement period level. The data builds on the bid offer pair data download completed in September but modifies it slightly by filtering out sleeper bids and offers (i.e. excessively large positive or negative prices).

BSUoS charges and metered volume at the NBP has been added.

The BMRS dynamic data has been summarised to the period level. To decide which value to use for the period, the one that applies for the most time in the settlement period is the one that has been selected.

The complete list of variables added to the download facility is as follows:

22nd September, 2008

BM Unit Bid Offer Data Bulk Data Download

The BM Unit Bulk Data Download page has been modified to provide more information. The new modification allows the user to download BM Unit bid offer data. The new functionality combines data from BMRS data and settlement file data to get the most recent data for a bid offer pair including the most up to date accepted bid and offer volumes and cashflows. As always BMRS data whilst only a day behind is frequently inaccurate and is updated in the settlement files. A little bit of clever analysis has been added which calculates the actual available volume for the half hour for the bid offer pair. What does this mean? Essentially code has been written that analyses the bid offer pair profile and FPN profile and MEL/MIL profile to find the proportion (if any) of the bid offer pair that is available to NGC for balancing. For example, if a power station BM Unit declares a bid offer pair with a level of 10MW, if the MEL profile is between this value and the FPN then the all the volume of the bid offer pair will not be able to be utilised because of the MEL ceiling. This has been quite difficult because it involves adding and subtracting MW profiles which is logically difficult in code.

Please note that this page has the capability to produce very large files, very quickly. Always save the output before trying to open it in Excel because it is very likely that the size of the file will exceed Excel's 65536 line limit. This page is best used for populating your own desktop databases (like Microsoft Access).

In addition to the BM unit, settlement date and settlement period and bid offer pair number the data items available are as follows:

  • Bid Price the bid price for the bid offer pair.
  • Offer Price the offer price for the bid offer pair.
  • Bid Cashflow the bid cashflow from bid offer acceptances that intersect this bid offer pair.
  • Offer Cashflow the offer cashflow from bid offer acceptances that intersect this bid offer pair.
  • Accepted Bid Volume the bid volume from bid offer acceptances that intersect this bid offer pair.
  • Accepted Offer Volume any offer volume from bid offer acceptances that intersect this bid offer pair.
  • Priced Accepted Bid Volume any bid volume from bid offer acceptances that intersect this bid offer pair that are not arbitrage or NIV tagged.
  • Priced Accepted Offer Volume any offer cashflow from bid offer acceptances that intersect this bid offer pair that are not arbitrage of NIV tagged.
  • Potential Volume Available the volume available on this bid offer pair after being sliced by MEL/MIL.
  • Potential Volume Declared the volume declared on this bid offer pair with no MEL/MIL slicing.
  • Potential Bid Cashflow Available the bid cashflow available on this bid offer pair after being sliced by MEL/MIL.
  • Potential Offer Cashflow Available the offer cashflow available on this bid offer pair after being sliced by MEL/MIL.
  • Potential Bid Cashflow Declared the bid cashflow available on this bid offer pair with no MEL/MIL slicing.
  • Potential Offer Cashflow Declared the offer cashflow available on this bid offer pair with no MEL/MIL slicing.
  • Time From the start time in minutes from the start of the period.
  • Value From the start level.
  • Time To the end time in minutes from the start of the period.
  • Value To the end level

12th June, 2008

Balancing Mechanism Data

Functionality has been added to display bid and offer data.

1st January, 2008

Gas Fired Power Station Summary

18th December, 2007

Gas Fired Power Station Summary

The Gas Fired Power Station Summary page has been created to generate spreadsheets summarising gas input, station MWHrs output and derived thermal efficiency of gas fired BM Units. The CO2 emissions from burning this gas will be added to the spreadsheet in the near future.

10th December, 2007

Hot Standby Server

For disaster recovery purposes the code base has been updated to allow the maintenance of hot standby servers that can be used to replace the main server in case of a failure. Although the main server has never failed this will allow the main server to be replaced with a hot standby system in two hours.

BSC Party and Trading Unit Relationships

The code to update relationships between BSC parties and Trading units has been updated to derive the relationships using BM Unit data downloaded from the Elexon website for days between the end of the settlement data and the previous day. This allows interconnector data to be displayed one day behind instead of 5 working days behind.

Excel Spreadsheet Generator / Download Enhancement

The code to generate Excel spreadsheets has been improved to pass the spreadsheet size in bytes through to the user's browser providing feedback during the final stage of download to the user's machine.

System Price Summary Spreadsheet Changed

The system price summary spreadsheet page has been updated to provide more information. Settlement Period level data is now included.

31st October, 2007

Triad Data Summary Spreadsheet

The TNUoS Period Data Spreadsheet for a TNUoS Year page has been updated to provide more information. Demand forecasts are now included, this includes day ahead (DF), 2 to 14 days ahead (NDFD) and 2 to 52 weeks ahead (NDFW) data. The spreadsheet has been modified further to present a table with peak data for each day and the current predicted Triad numbers as well as a glossary.

15th October, 2007

BM Unit Summary Data changes

The backend processes that bring BM Unit data from settlement files and BMRS data into summary tables has been finished. This functionality replaces the existing summary functionality that takes data only from settlement files. The upshot of this change is that now the summary data pages will have notification data up to a day behind. The metered volume data remains five working days behind.

All spreadsheets that summarise BM unit data have been changed over to the new data source. However, interconnector data and spreadsheets that reference BSC party level information will not show data more recent than five working days behind because they rely on BM Unit for BSC Party relationships that are derived from settlement data.

Energy Account Data Download

A new page has been added that can be used to download energy account data. The download energy account data for a date range page is used to download a CSV file containing energy account data for anything from one to all BSC parties for a date range at settlement period resolution.

Balancing Mechanism Data

Functionality has been added to display total bid and offer data.

17th September, 2007

Internet Explorer 7 Issues

As part of this process the code that is used to select the time range of the spreadsheet has been modified to allow different periods to be chosen. The allowable time periods are limited by performance concerns and Excel's column limit of 255 and row limit of 65536. Time periods are:

  • Day
  • Week
  • Month
  • Quarter
  • Calendar Year
  • Financial Year
  • TNUoS Period (Nov-Feb)

31st July, 2007

Internet Explorer 7 Issues

Microsoft brought out a new version of its browser, internet explorer (IE), some months ago. NETA reports customers have now started to upgrade and this has brought to light an issue. The previous version of IE (6) had a response time-out of 1 hour, the new version (IE 7) has a response timeout of 30 seconds. Some of the reports on the site take a long time to generate because they contain lots of complicated data and this new timeout setting means that IE 7 frequently gives up when waiting for these big reports to complete. The message that IE7 shows when it times out is not helpful saying things like "Cannot Find Server" which implies that there is a problem with the site which is not the case.

The solution to this problem is to change the way NETA reports generates reports. When a report is requested, the user is diverted to a page which shows the progress on the creation of the report. When the report is finished, a link is presented to the user to allow them to fetch the generated report. This progress page refreshes every 15 seconds which means that IE 7 now does not time out. It also provides more reassurance to the user that something is happening.

Reports that have been changed are as follows:

Progress on conversion of the report generation pages will be reported here as it progresses.

BM Unit Bulk Data Download

A new page has been added to the BM Unit summary page. The Bulk Data Download page is used to extract data from at BM Unit level using different filters. The first set of filters allows data to be extracted for BM Units at settlement period level using a BM Unit restriction based on the BM Unit type which can be chosen from one of : Notifying BM Units, Notifying CVA BM Units, Notifying SVA BM Units, Embedded CVA BMUnits ('E_') Only, Directly Connected CVA BMUnits ('T_' and 'M_') Only, Interconnector BMUnits ('I_') Only or SVA BMUnits ('2_') Only.

Please note that this page has the capability to produce very large files, very quickly. Always save the output before trying to open it in Excel because it is very likely that the size of the file will exceed Excel's 65536 line limit. This page is best used for populating your own desktop databases (like Microsoft Access).

23rd-31st January, 2007

Problem with Elexon Supplying SAA-I0142 version 6 files

The November release has eventually rippled through to the system that serves P114 data files. A failure in the copy job at the Elexon end meant that SAA-I0142 files were not available between Tuesday 23rd and Monday 29th January. The issue was raised with Elexon and has been resolved. This has caused a back log which has taken a day to get through. The databases are now back-up to date with SAA data.

15th January, 2007

Balancing Mechanism Reporting Service Historical Data Service Goes Live

Elexon have gone live with the historical BMRS data service and data now goes back to 1st Jan, 2002. NETA reports has been set on with importing this data and it is estimated that it will take approximately a month to upload the five and a bit years of data into the database.

15th December, 2006

Triad Data Summary Spreadsheet

A new page has been added to the summary data section. The TNUoS Period Data Spreadsheet for a TNUoS Year page is used to generate an excel spreadsheet that contains system period demand for a TNUoS year (Nov to Feb). The spreadsheet uses the same calculation methodology as NGET which means that it can be used to validate NGET calculations of TNUoS periods and also to back up ongoing analysis during a winter so that potential TRIAD periods can be called with more accuracy. The spreadsheet contains INDO data for each day as well as metered data as appropriate for as many settlement runs as necessary upto about eight days after the SF run for the last day of February.

30th November, 2006

Balancing Mechanism Reporting Service Data

After some discussions with Elexon and co-incident with a project they are running internally, NETA Reports is starting to be modified to take in data from the Balancing Mechanism Reporting Service. This data is picked up from the BMRS as a large data file with data for the previous day at around 2AM. Although this data is only notification data it will combine with the existing settlement data that we get five working days behind to add extra value to the service.

The data currently goes back to 10th August, 2006. It is envisaged that this data will be used to provide BM analysis and summary reporting which is only one day behind. NETA reports is inching towards real-time market information.

20th July, 2006

Auto-Reporting Enabled

Phase 3 of the development of www.netareports.com commences. Auto-Reporting allows the user to define a customisable reports which can then be automatically emailed to them when the data becomes available on the service.

Current reports available are at the fuel type level, the super party level and a combinations of fuel type and super party. Reports are also available at three resolutions, daily, weekly and monthly.

The fuel type level reports allow the user to view which fuel technologies are used to generate electricity, which fuel technologies get called in the balancing mechanism and how these fuel technologies perform in non delivery charges.

The super party level reports aggregate data at the level of the ownership of assets, these reports allow the user to view the market share of super parties in generation, which super parties get called in the balancing mechanism and how these super parties perform in non delivery charges.

The super party fuel type reports aggregate data at the super party and fuel type level allowing the user to see which super parties use which fuel types. These reports allow the user to see market share in the SVA market and market share in each individual generation technology.

These reports are accessed via the reports base page

.

A subset of the available reports have been made available as a free report which is available for download at the free report page. Free reports can be downloaded via the free email page.

2nd June, 2005

Enhancements to BM Unit Summary Data

The code that creates summaries of BM Unit performance has been re-written. The first key change is that the undo bid and offer data has been striped out. Previously bid and offer volumes were aggregated together in the conventional format. Now accepted bids which are undoing previously accepted offers are striped out as "undo" offers. Similarly the corresponding undo bids can be stripped out also. This means there are now new worksheets and columns in all spreadsheet reports showing the following:

  • Total Accepted Undo Bid Volume - The aggregate undo bid volume.
  • Total Accepted Undo Offer Volume - The aggregate undo offer volume.
  • Undo Bid Cashflow - The aggregate undo bid cashflow.
  • Undo Offer Volume - The aggregate undo offer cashflow.
  • Undo Bid Price - The aggregate undo bid price.
  • Undo Offer Price - The aggregate undo offer price.

Another change is the creation of a BOA Count. This is the number of Bid/Offer acceptances that touch the time period in question for the entity. i.e. if the report is daily fuel type data then the report will show the number of BOAs for that fuel type and that day.

31st May, 2005

NETA Reports has a new home ...

NETA reports currently runs on a rented server in a data centre somewhere in Slough. Today phase one of a migration process was completed when the system was installed on a new box running inside a data centre in Middlesbrough. The new platform has more disk space as the database backend for the server is currently 100GB and forecast to grow to 250GB in six months.

Data updates on the production box will now pause whilst the new box has final testing in its new location. When data update is complete the DNS settings for the www.netareports.com domain will redirect to this new box.

One of the enhancements to the system implemented on the new box is a revised BM unit summary system that splits achieved bid and offer prices to identify reverse prices and volumes.
