    ERCOT NEWS: October Board Meeting Highlights


    Board approves nodal contingency funds for post go-live

    The Board of Directors for the Electric Reliability Council of Texas, grid operator and manager of the electric market for most of the state, voted last week to use a portion of the nodal contingency fund for market stabilization expenses – avoiding the need for a fee increase in 2011. 

    ERCOT filed a request today with the Public Utility Commission seeking approval to use $25.2 million of the remaining nodal budget funds for nodal expenses occurring after the Dec. 1 go-live date

    The nodal market implementation is funded by a temporary nodal surcharge established by the commission to support the nodal budget.  The budget, which was revised in 2009 to $644 million, included $58.6 million in a contingency fund to be used only with the board’s authorization.  None of the board’s discretionary fund has been used to date, and the fund has increased to $117.7 million as the nodal program monthly under-runs have been added to it. 

    The $25.2 million includes $13.3 million for one-time nodal project charges expected in 2011, such as systems stabilization, and $11.9 million is for recurring annual charges, such as hardware and software licensing and maintenance.  These will be added to ERCOT’s base operating costs starting in 2012. 

    Directing the $25.2 million to post go-live expenses is expected to extend the collection period of the nodal surcharge by approximately three months, from approximately January 2013 to March 2013. 

    “Using the board’s discretionary fund for post go-live expenses will enable ERCOT to effectively manage the transition to the nodal market in 2011 without seeking increases in either the nodal surcharge or the ERCOT system administration fee,” Controller Mike Petterson said.   

    Without use of the board discretionary fund, the 2011 preliminary budget schedules suggest an increase of $0.05 per megawatt-hour (MWh) in the system administration fee would be needed. 

    The system administration fee, which is assessed on wholesale energy transactions, has been set at $0.4171 per MWh for the last six years (approximately $0.42 per month, based on a 1,000-kilowatt-hour/month bill).  The nodal surcharge, which is assessed to generation owners, is $0.375 per MWh and will be discontinued when costs for the nodal market implementation are recovered. 

    The board is scheduled to vote on the 2011 budget in November.

    Credit parameters, market rule changes approved

    In other action, the board established the credit requirements for congestion revenue rights auction, setting the obligation margin adder at $0.75 and the multiplier at zero, as recommended by the Technical Advisory Committee.   

    The board also approved 14 nodal protocol revisions (NPRRs), and one Nodal Operating Guide revision request (NOGRR):

    • NPRR 219: Resolution of Alignment Items A33, A92, A106, and A150 – TSPs Must Submit Outages for Resource-Owned Equipment and Clarification of Changes in Status of Transmission Element Postings

    CEO reports favorable year-end budget anticipated

    In his monthly update, CEO Trip Doggett said the year-end budget is projected to have an $11 million favorable variance, up from 10.6 million last month.    

    The unusually hot August and warmer-than-normal September were reflected in energy usage above forecast and in comparison to last year.  Actual energy usage year-to-date for the ERCOT region through September is 249,361,862 megawatt-hours (MWh).

    Market, grid and IT reports presented

    Highlights from the Market Operations Report include:

    • Significantly lower retail switching activity in August/September 2010 as compared to the same period in 2009 (higher numbers in August/September 2009 were due to the new expedited switch rule that allowed more switches to be completed within the reporting month);
    • August wholesale energy volumes were up 7 percent in 2010 compared to 2009; also reflected in the new ERCOT-wide peak demand records set in August 2010;
    • Load zone prices for balancing energy increased in August due to higher load volumes;
    • Local congestion (volumes and costs) are down significantly from the same period last year;
    • Two new retail electric providers and five new energy schedulers have been added. 

    Highlights from the Grid Operations and Planning Report include:

    • ERCOT is currently tracking 188 active generation interconnection requests totaling more than 65,000 MW; includes almost 39,000 MW of wind generation;
    • Proposed transmission improvements under review total $80.8 million;
    • Transmission projects endorsed in 2010 total $230.4 million;
    • All projects in engineering, routing, licensing and construction total $9.4 billion. 

    Quarterly Update on PRR 763 (Wind Power Forecasts)

    • Concludes that protocol changes have reduced the tendency to under-forecast the wind output and improved accuracy of the wind forecasts.
