The Trump administration announced in December 2018 its proposed replacement rule defining “waters of the United States.” Under the proposed rule, the number of wetlands that fall outside of federal jurisdiction is expected to increase.

Phillip Bower and Megan McLean weigh in on what this means for state regulation of non-federal wetlands in the recent

Per- and polyfluoroalkyl substances (“PFAS”) are synthetic chemicals used in a number of industrial processes and in the manufacturing of certain consumer goods because of their fire resistance and because they repel oil, stains, grease, and water. There are approximately 3,500 different compounds under the umbrella of PFAS. Some of these were used in firefighting foam, which in some places, including near airports, were spread over the ground to prevent forest fires. The most well-known versions, and considered to be of greatest concern, are long chain PFAS, perfluoroctanoic acid (“PFOA”) and perfluoroctane sulfonate (“PFOS”).

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

On August 21, 2018, the Environmental Protection Agency (EPA) released a prepublication copy of its proposed Affordable Clean Energy (ACE) rule. If adopted, the rule would (1) establish emission guidelines for greenhouse gas emissions from existing electric utility generating units (EGUs); (2) revise the regulations governing how states implement the emission guidelines; and (3) revise the New Source Review (NSR) program to allow modification to existing EGUs without triggering permitting requirements.

The Clean Power Plan regulations adopted by the Obama administration would have limited GHG emissions by directing states to reduce emissions by applying a combination of three “building blocks” as the best system of emission reduction (BSER), which consisted of:

1)    Improving heat rate at affected coal-fired steam generating units;

2)    Substituting increased generation from lower-emitting natural gas combined cycle units for decreased generation from higher-emitting affected steam generating units; and

3)    Substituting increased generation from new zero-emitting renewable energy generating capacity for decreased generation from affected fossil fuel-fired generating units.

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.
