Board Approves Revised Budget for Nodal Program

The ERCOT Board of Directors voted Tuesday to increase the nodal costs to be financed to $269.1 million.  Financing costs will be $42.2 million for a total of $311.3 million in expenditures to be recovered through the nodal surcharge.  The board also endorsed ERCOT staff to proceed with a filing at the Public Utility Commission (PUC) to increase the nodal surcharge to $0.169 per megawatt hour (MWh), from the current $0.127 MWh. 

The board’s finance and audit committee chair reported that the committee had reviewed the options and endorsed the staff’s recommendation for the budget and surcharge increase. 

After a nodal update from staff and discussion, Board Chair Mark Armentrout summarized the major reasons for the budget increase: changes to the project scope, adjustments in the schedule necessitated by the scope changes, and vendors coming in over budget, primarily from one vendor. 

The program’s previous expenditure estimate of $248.9 million (including $33.5 million in financing costs) was authorized by the board in January 2007.  The PUC approved the current nodal surcharge in May 2007 and required that it be paid by energy schedulers (Qualified Scheduling Entities) representing generation resources. 

The nodal market implementation is currently on schedule for the Dec. 1 launch, said Jerry Sullivan, executive director of the market redesign.  The greatest risks for the go-live date include a tight schedule for the delivery and testing of the Market Management System; infrastructure constraints (power, space and cooling limiting the speed of some projects and trials); and integration issues (building 400-500 interfaces and working with the three main vendors on integration of models and communications).

The final critical release of the Market Management System is scheduled for mid April, Sullivan said.  The board asked for an update at the May meeting on the likelihood of meeting the schedule launch date.  A market readiness determination is scheduled for August.  

Additional Board Action

In other board action, the directors approved four Protocol Revision Requests (PRRs) and three Nodal Protocol Revision Requests (NPRRs):  

PRR 727: Process for Transition to Nodal Market Protocol Sections 

PRR 738: Remove Old Versions of Standard Form Agreements 

PRR 744: Revision to 16.2.8, Monitoring of Creditworthiness by ERCOT 

PRR 748: Settlement during EDS 3 LFC Testing 

NPRR 078: Simplifying the Dispute Process 

NPRR 086: Settlement Clarifications to RUC Capacity Shortfall Ratio Share Formula 

NPRR 087: Market Monitor Terminology Change 

Armentrout recognized Don Ballard, the new general counsel at the Office of Public Utility Counsel.  He replaces Suzi McClellan as the ex officio board member representing the residential consumers.  Armentrout praised McClellan for her service on the board which began in 1999. 

Armentrout also expressed the board’s appreciation to the ERCOT staff for system reliability in 2007, cost management, customer service, stakeholder committee support and insuring fair and impartial access to the grid. 

ERCOT Staff Reports

CEO Bob Kahn updated the board on ERCOT’s credit risk study.  In mid 2007, the board authorized ERCOT to engage an outside consultant Oliver Wyman to quantify potential credit exposure in the market via a statistically-based model to educate stakeholders about the level of credit risk in the market and to provide a common framework for stakeholders to discuss the level of credit exposure. 

Oliver Wyman is wrapping up the study, and ERCOT will begin vetting the preliminary results with stakeholders during the next few weeks.  The study results will be presented at the board’s Feb. 19 meeting. 

The Market Operations Report highlights included:

  • Retail switching activity is down 13 percent compared to last year.
  • Residences that have switched to a provider other than the incumbent retail electric provider are at 41 percent of electric service identifiers (ESI IDs), compared to 36 percent last year.
  • Small non-residential migration to another provider is at 44 percent of ESI IDs, compared to 37 percent last year.  Large non-residential migration is at 71 percent compared to 72 percent last year.
  • Three new retail electric providers have been qualified: Chain Lakes Power, Etricity, and Juice Energy.
  • Three new energy schedulers (QSEs) have been added: Airtricity QSE Southwest, Prier Energy, and Juice Energy. 

The Information Technology Report included summaries on performance metrics, net service availability, retail transaction processing, Texas Market Link availability, and MarkeTrak availability.

Energy Use for 2007 Up Slightly from Last Year

Preliminary ERCOT settlement data for demand and energy indicates total energy use for 2007 was 307 million MWh, which was 0.4 percent higher than 2006.  The total was 1.9 percent below the normal weather forecast for consumption.   

The unofficial peak demand for 2007 is 62,188 MW, which occurred on August 13 in the 3-4 pm interval, based on 60-day final settlement data which is subject to change after the six-month true-up.  The all-time maximum peak demand is 62,339 MW, set on Aug.17 in the 4-5 pm interval.  

Energy consumption for the year as measured by fuel type is:

  • Natural gas – 45.5 percent
  • Coal – 37.4 percent
  • Nuclear – 13.4 percent
  • Wind – 2.9 percent
  • Water – 0.4 percent
  • Other – 0.4 percent

ERCOT Tracking 220 Generation Requests
