In the wake of winter storm Uri, ERCOT market participants are grappling with the resulting financial fallout. Many are now familiar with actions the Texas Public Utility Commission took during the February weather event with the intent to bring and maintain as much generation online as possible – notably ordering ERCOT to implement a temporary adjustment to the scarcity pricing mechanism designed to result in real time prices reaching the system-wide high offer cap at the statutory maximum of $9,000/mWh during the height of the generation forced outages.

Now, more than two months removed from the storm, the resulting financial impacts are having serious repercussions across the ERCOT market. Several retail electric providers have filed for bankruptcy, lawsuits are underway against a wide swath of market participants and regulators (ERCOT, the Public Utility Commission, generators, REPs, gas utilities, etc.), and countless market participants are faced with paying record-high bills for a range of reasons, including the need to procure energy in the real-time market during scarcity conditions, to obtain high priced gas supplies, to cover positions when their resources incurred outages, or exposure to uplift of default amounts owed to ERCOT. Complicating that, ERCOT has failed to pay many who did perform during the storm due to the short payment of some market participants, which means those who performed may not soon realize revenue associated with that performance. Additionally, the higher prices for power and ancillary services prompted ERCOT to substantially increase Counter-Party collateral requirements. Last month, the Public Utility Commission issued an order in Docket 51812 extending the deadline to dispute ERCOT invoices related to the winter event from 10 business days (under the current ERCOT Protocols) to six months. Since this order, the Commission has taken no additional action to address issues related to settlement invoices resulting from the storm.…

Bottom Line Up Front: The Department of Energy (DOE) will implement new cybersecurity programs to enhance energy sector resilience. DOE’s announcement coincides with the Senate Energy and Natural Resources Committee’s support for the DOE’s Office of Cybersecurity, Energy Security, and Emergency Response (CESER). Expect to see resilience to cyber attacks in future government procurement activities.

On March 18, 2021, CESER announced several new research programs designed to enhance the safety and resilience of the U.S. energy sector. The Trump administration established CESER to protect critical energy infrastructure by assisting oil, natural gas, and electricity industries secure their infrastructure. Currently, energy infrastructure faces threats not only from climate and natural hazards, but also evolving and increasing physical and cyber threats.…

On Friday, May 1, 2020, President Trump issued a new Executive Order (the Bulk-Power Order) to prohibit transactions within the U.S. for the acquisition or installation of certain “bulk-power system electric equipment” which is sourced from foreign adversaries. In the Bulk-Power Order, President Trump expressed a determination that “the unrestricted foreign supply of bulk-power system

Lawmakers of the 86th Texas Legislature passed several bills in regular session related to storage and cybersecurity, as well as a bill extending the expiration of a Chapter 312 tax abatement program that benefits renewable energy. These energy-related bills passed by the Texas Legislature are discussed below, as are notable bills that failed to gain traction this session.…

By the time the March 8, 2019 bill filing deadline for the 86th Texas Legislature passed, many bills concerning the electric industry had been filed. Storage, cybersecurity of the electric grid, and capital project tax abatements are among the energy issues Texas lawmakers are considering. This reviews the major filed bills before the current Texas Legislature.…

At the January 17, 2019 Open Meeting, the Public Utility Commission of Texas (Commission) addressed several highly contested issues, including storage, Operating Reserve Demand Curve, Real-Time Co-optimization, and Marginal Losses. First, in Project No. 48023, Rulemaking to Address the Use of Non-Traditional Technologies in Electric Delivery Service (the Battery Project), dealing with utility ownership of battery storage, the Commission decided to defer further action until Texas Legislature’s regular session concludes. This decision comes after 63 comments were filed with the Commission, expressing widely varying views on whether a transmission and distribution utility within ERCOT may legally own and operate battery storage facilities. The Commission previously submitted through its Scope of Competition Report a request for the Legislature to enact legislation clarifying this legal point.…

The Public Utility Commission of Texas has finalized the recommendations it will include in its upcoming 2019 Report on the Scope of Competition in Electric Markets in Texas to the 86th Texas Legislature, which goes into session January 8, 2019. The Commission voted on the recommendations at its December 20, 2018 meeting; the most significant…

Potomac Economics, the Independent Market Monitor (IMM) for the ERCOT market, released its “2017 State of the Market Report for the ERCOT Electricity Markets,” which contains several important insights for market participants and offered seven recommendations for market improvements.

Prices and Demand Move Higher in 2017

First, the IMM found that energy prices increased 14.7% over 2016, to $28.25 per MWh. This price is still significantly less than 2011’s average annual price of $52.23 per MWh and even 2014’s average annual price of $40.64 per MWh. The 2017 price increase correlates with a 22% increase in the cost of natural gas, the most widely-used fuel in ERCOT, as fuel costs represent the majority of most suppliers’ marginal production costs.  The IMM also found price convergence to be very good in 2017, with the day-ahead and real-time prices both averaging $26 per MWh.  However, the absolute difference between day-ahead and real-time prices still increased from $7.44 per MWh in 2016 to $8.60 per MWh in 2017.

Average demand also increased, rising 1.9% from 2016, with demand in the West Zone seeing the largest average load increase at 8.3% (possibly due to oil and natural gas production activity in that zone). Despite this increase in average demand, peak demand in ERCOT reached 69,512 MW on July 28, 2017, which is lower than the ERCOT-wide coincident peak hourly demand record of 71,100 MW, set on August 11, 2016.  Even with general price and demand increases, market conditions were rarely tight as real-time prices didn’t exceed $3,000 per MWh and exceeded $1,000 per MWh for just 3.5 hours in all of 2017.

Congestion Costs Skyrocket

Surprisingly, the IMM found congestion in the ERCOT real-time market increased considerably, contributing significantly to price increases in 2017 with total congestion costs equaling $967 million – a 95% increase from 2016.  The IMM stated that this increase is due to three main factors: (1) limitations on export capacity from the Panhandle; (2) planned outages associated with the construction of the Houston Import Project; and (3) the aftermath of Hurricane Harvey.

While congestion was more frequent in 2017 than in 2016, congestion on the North to Houston constraint declined after June due to the completion of a new 1,200 MW combined cycle generator located in Houston. The completion of the Houston Import Project in 2018 should reduce congestion in this area even further.…

It appears the Texas Legislature has taken note of the several news articles and industry insiders sounding the alarm bells for ratepayers to brace for record high electricity prices this summer in a market applauded for its consistently low prices. The Committee convened because the Lt. Governor charged it to study/respond to the reserve margin…

On the heels of last week’s Hearing on the Merits, the proposed transition of Lubbock Power & Light (“LP&L”) from the Southwest Power Pool (“SPP”) to the Electric Reliability Council of Texas (“ERCOT”) was back on the agenda at this week’s Public Utility Commission of Texas (“PUCT” or the “Commission”) open meeting.

During last week’s hearing Chairman DeAnn Walker instructed representatives of LP&L and ERCOT to finalize an agreement in which LP&L pays to help counterbalance some of the transmission infrastructure costs that may be incurred by ERCOT customers as a result of the transition. Walker also advised LP&L and SPP to try to reach a similar agreement for the benefit of the ratepayers in that region.

In response to that directive, LP&L, the Commission Staff, the Office of Public Utility Counsel (“OPUC”), and the Texas Industrial Energy Consumers (“TIEC”) have reached an agreement in principle that would, if approved by the Commission, resolve the outstanding ERCOT issues. A letter summarizing the terms of the agreement in principle filed in PUCT Docket No. 47576 last week states that LP&L will pay $22 million each year for five years to ERCOT wholesale transmission customers through the tariff proposed by Commission Staff to shield ERCOT ratepayers against the expected financial impacts of LP&L’s requested transition, and that LP&L will pay SPP’s study costs of approximately $172,000.

Discussions with ERCOT continued this week regarding what terms the final transition agreement will need to contain to satisfy ERCOT’s concerns. LP&L has completed a draft settlement agreement with ERCOT’s guidance in mind and circulated it to all parties the day before the open meeting. LP&L’s attorney conducted preliminary conversations with the parties regarding the draft and the settlement discussion is ongoing; LP&L expects to gain more guidance from the parties over the course of the next several days.…
