Notice of Weekly Natural Gas Storage Report Changes

Originally Released: November 26, 2013

Updated: December 11, 2013

The Energy Information Administration (EIA) is changing the Weekly Natural Gas Storage Report (WNGSR) for the following:

  • The table will now include a column for implied flow
  • Columns for reclassification flags - to be indicated by an upper case C - are added to the table
  • New filenames for the text (wngsr.txt) and csv (wngsr.csv) file formats

The web address and EIA's Gatekeeper delivery methodology will remain unchanged.

For more background on the changes to the report please review previous notice from September 23, 2013.

Testing will be provided. Dates and times are listed below. We ask that customers who normally access the data at 10:30 a.m. on Thursdays for their participation.

Files that will contain the new columns for implied flow and reclassification flags are:

  • ngs.html
  • wngsr.txt
  • wngsr.csv
  • wngsr.json

Files names that are changing:

  • blackberry.txt - wngsr.txt
  • weekly.csv - wngsr.csv

TESTING

The test version of WNGSR is located at: http://ir.eia.gov/ngs_test/ngs.html.

Testing will be under the same conditions that we normally use to release the data at 10:30 a.m. We will conduct four tests for the WNGSR.
Notice: Due to the closure of the Federal Government on Tuesday, December 10, 2013 the test for that day has been rescheduled for December 13, 2013.

Day Date Product Time Test Scenarios
Tuesday December 10, 2013 WNGSR 11:00 a.m. Oct. 11, 2013 data replacing Oct. 4, 2013 - Rescheduled
Friday December 13, 2013 WNGSR 11:00 a.m. Oct. 11, 2013 data replacing Oct. 4, 2013
Friday December 13, 2013 WNGSR 3:00 p.m. Oct. 18, 2013 data replacing Oct. 11, 2013
Tuesday December 17, 2013 WNGSR 11:00 a.m. Oct. 25, 2013 data replacing Oct. 18, 2013
Friday December 20, 2013 WNGSR 11:00 a.m. Nov. 1, 2013 data replacing Oct. 25, 2013

The four tests will use test data files reflecting periods released in early October 2013. As each test occurs, the test files will be replaced with data for the next week.

You can access the data how you normally do. Please start your test to access the data five minutes before the scheduled test release time. Trying to access the site during that time period will result in a 503 error - "Page Temporarily Unavailable," and a message stating that the data will be automatically sent to your PC in "x" number of seconds. ONCE YOU RECEIVE THIS "503 ERROR" YOU NEED DO NOTHING FURTHER.

The test data will be automatically released to you precisely as scheduled above. For robot customers scraping the html, you will probably need to make some changes to your code.

If you have any questions prior to or after the test, please contact us at: gatekeeper@eia.gov.

After tests have concluded we will announce the implementation date for these changes.

If you are receiving this message and are not the individual who normally accesses the Weekly Natural Gas Storage Report for your organization, please pass this information on to the responsible person.

Detailed testing instructions:

Test directory address: http://ir.eia.gov/ngs_test/ngs.html.

1. Five minutes before the scheduled time on the test day, access the test product with the appropriate URL.

2. After you have accessed the test URL, you will receive a customized "503 Error - Page Temporarily Unavailable" like the one below:

503 - Sorry! This file is temporarily unavailable.

A new version of this file is currently pending release.

This page should automatically refresh to download the new release at 11:00:00 AM (in 56 seconds)
If it does not, click here to manually re-try.

(Estimated time remaining: 56 seconds)



3. Once you receive the 503 error page, DO NOTHING ELSE. The file you requested will be automatically delivered to you when it is released.

4. Following the test, please email EIA at gatekeeper@eia.gov and let us know how the test worked at your location.

5. If you are not the individual who normally accesses the WNGSR for your organization, please pass this information on to the responsible person. If you have any questions prior to the test, please contact EIA at gatekeeper@eia.gov.

NOTE: Any automated retrieval program that excessively accesses information from EIA's website is prohibited. Excessive robot activity on EIA's website can cause delays and interfere with other customers' timely access to information. The EIA is committed to promptly release information according to established schedules. The EIA retains the right to limit or deny the use of any robotic activity that EIA considers an excessive or malicious practice (for example, robots that access or download information from EIA websites multiple times per second).
