NERC Generating Availability Data System (GADS) Conventional and Wind Training - 2018

by ronfluegge 30. April 2018 09:33

Reminder:  NERC Training Announcement 

The Generating Availability Data System Working Group (GADSWG) implements a uniform approach to reporting and measuring North American generating plant availability, performance and other related reliability data.

Conventional GADS training will include items such as how GADS data is used, events and performance, combined cycle component versus block reporting, the case for event reviews, review of cause codes, examples of poorly reported events to NERC, understanding Data Reporting Instructions (DRI) Appendix F: Equations and the data submittal process at Open Access Technology International (OATI).

Wind GADS training will include the reporting implementation timeline, entity registration, processes and reports. Additionally, the data submittal process through the NERC GADS Wind reporting application will be covered.

In 2018, the GADSWG will offer training at the following locations:

Week of June 18th at Open Access Technology International, Inc. (OATI) in Minneapolis, MN

Training classes conducted each week are:

  • An introductory session for new conventional GADS reporters on Monday
  • Conventional GADS material will be covered on Tuesday 
  • Appendix F  and analytics in conventional GADS will be covered on Wednesday
  • GADS Wind material will be covered on Thursday and Friday

Training Schedule:

  • Monday | Noon – 1:00 p.m. Registration | 1:00 p.m. – 4:00.p.m. Introductory Session
  • Tuesday | 9:00 a.m. – 5:00 p.m. | Conventional GADS
  • Wednesday | 9:00 a.m. – Noon | Conventional GADS Appendix F Equations and Analytics
  • Thursday | 9:00 a.m. – 5:00 p.m. | Wind GADS
  • Friday | 9:00 a.m. – Noon | Wind GADS

Although registration is required, there is no fee for this training.  Continental breakfast and lunch will be included.

GADS Reporting for Wind

by ronfluegge 27. March 2018 15:05

The North American Electric Reliability Corporation (NERC) is phasing in mandatory quarterly GADS-W reporting requirements over three years for wind plants with an installed capacity over 75 MW and a commissioning date of January 1, 2005 or later. Plants with a capacity of over 200 MW started reporting on January 1, 2018 with 100 MW and 75 MW sites required to begin reporting on January 1, 2019 and January 1, 2020, respectively. 

The quarterly GADS-W reporting consists of submitting three reports: 

  1. Sub-Group: consists mainly of site characteristics, location, and equipment information 
  2. Performance: general site performance, including unavailability (forced, maintenance, or planned) for reasons outside of management control 
  3. Component Outage: identifies the general area of reason for the loss of production using a list of component (system) codes to ensure consistency in reporting

Generation from Gas, Coal Fell in 2017 as Renewables Rose

by ronfluegge 23. March 2018 11:32

The year-end electric power report from the Energy Information Administration showed overall generation fell by 1.5 percent in 2017, but different power sources experienced different changes in use.

Natural gas experienced a relatively steep decline of 7.7 percent last year, with coal generation falling 2.5 percent. Natural gas remained the most-used fuel source for the third year in a row, though its biggest annual decline on record significantly narrowed the gap with coal. Additionally, 2017 was the first year since 2009 that both natural gas and coal-fired generation fell in the same year.

Coal accounted for more than half of the electric capacity retired in 2017, with 6.3 GW of the 1.2 GW total. For the first year in at least a decade, no new coal-fired generators were added.

Though 4 GW of natural gas capacity was retired, 9.3 GW of new natural gas came online during 2017, with 8.2 GW of the total consisting of combined-cycle units.

At the same time, wind generation grew 12 percent and solar generation increased 46.9 percent. Now, wind made up of 6.3 percent of total net generation and solar reached 1.3 percent. Nearly 6.3 GW of wind turbines and 4.7 percent of solar systems were added in 2017

Hydroelectricity had another strong year, reaching 7.5 percent of total generation thanks to record precipitation in California.

Nuclear generation held nearly steady, falling by 0.1 percent.
