Hurricane Harvey’s Impact on Texas Electricity Grid

High winds and significant flooding along the Texas Gulf Coast substantially impacted the Texas electricity grid.  The transmission and distribution infrastructure sustained severe damage in the southern portion of the state as a result of Harvey’s landfall.  10,000 megawatts of electricity was lost to the grid according to the Electric Reliability Council of Texas (ERCOT).

The loss of generation capacity was offset by a large drop in electricity demand across the state.  The loss in demand was a direct result of downed transmission lines.  Leaving hundreds of thousands of Texans without power at times.  The grid also benefited from a drop in temperatures across the state during the period when the loss of capacity was at its greatest.

Many factors associated with the storm combined to reduce electricity output.  Several power plants went offline as a result of flooding that impacted the delivery of fuel supplies to the generator facilities.  These same transportation difficulties kept personnel needed to run the plants from getting to work.

Near the coast where winds exceeded 130 miles per hour, many high voltage transmission lines were taken out of service by the damaging winds.  Further inland in the Houston area, flooding took a larger toll on transmission facilities.  Capacity was also lost due to loss of wind power.  Wind turbines are turned off when wind exceeds 55 mph in order to avoid damaging the equipment.

Power loss along with the failure of a backup generator were to blame for explosions at the Arkema chemical plant.  The plant stored chemicals that become volatile when not cooled to a certain temperature.

Meanwhile, many electricity providers in Texas stepped up to help in relief and rebuilding efforts.  NRG, the parent company of Reliant Energy and several other electric brands in Texas donated one million dollars to organizations including the Red Cross, and the J.J. Watt Houston Flood Relief Fund.   Direct Energy, the parent company of Bounce energy and the Direct Energy retail brand is matching donations up to $25,000 the Red Cross.  TXU Energy is allocating $500,000 to help customers who are unable to pay their electric bills in the wake of Harvey.

Buffett May Be Buying Oncor

Legendary investor Warren Buffett may be close to buying Texas’ largest electricity utility according to reports.   Once part of the giant energy concern that included the retail arm of TXU, Oncor Electric Delivery has been up for sale for some time since the bankruptcy of its parent holding company Energy Future Holdings.

There have been numerous attempts to sell the unit already.  Offers by Hunt Consolidated Inc and NextEra Energy have both hit roadblocks thrown up by Texas regulators.  Buffett’s company Berkshire Hathaway is said to be offering $17.4 billion for the utility.

ONCOR is responsible for the transportation and distribution of electricity for a large portion of the Texas electricity marketplace including the Dallas and Fort Worth areas.  It is one of a handful of regional monopolies allowed to transmit the electricity that retail electricity providers sell to residential and commercial end users.   10 million electricity users in Texas are served by ONCOR.

Texas Electric Grid Has Adequate Capacity for Summer/Fall 2017

ERCOT has released its latest Seasonal Assessment of Resource Adequacy for the summer months.   The organization anticipates that the Texas electric grid will have no trouble meeting the demand for electricity during the hot summer months from June – September.   The report forecasts a peak demand of 73,000 megawatts for electricity during the period.  This is based on the average demand for that same period over the last 14 years.

Against this demand, officials are projecting a peak production capacity of 83,000 MW.  Included in this total is 2,500 MW of new natural gas powered generation and 800 MW of new wind and utility scale solar generation.  Because of the intermittent nature of wind and solar energy generation, only 350 MW of peak power from wind and solar are being included in the projections of summer capacity.

There is no new coal power electricity generation included in the forecast.  Coal continues its multi-year decline across the U.S. and in Texas in particular due to a combination of environmental regulations, competition from renewable energy sources and cheap natural gas.  Cheap natural gas more than anything else has helped to keep electricity rates in Texas low for several years.

In a separate report, ERCOT looked at generation over the next five years.  The trend is unsurprising.  Summer capacity is expected to rise to over 87,000 MW hours in 2022.  Wind, Solar and Gas are expected to grow both in real terms and as a percentage of total capacity.  Coal is expected to continue to decline.

The Texas electricity market continues to be a model for the benefits of energy deregulation.  Capacity and reliability continue to improve.  This is occurring with a lower per kWh environmental impact thanks to the proliferation of renewable energy in the state.  Additionally, giving consumers the power to choose their electricity provider has led to innovations in the way electricity is sold to end users.   All of this is occurring in an environment of sustained low rates.

Oncor Proposes Electricity Rate Increase for Many Texans

Oncor-Electricity-MapOncor Electric Delivery Company has filed a request with the Texas Public Utility Commission to increase electricity rates for those in its delivery area.  This is primarily North Texas which includes Dallas, Fort Worth and surrounding cities.  It also includes parts of Central Texas including Temple and Killeen as well as parts of Western Texas including Midland and Odessa.

According to the company, the proposed rate increases are necessary to offset nearly $8 billion dollars spent by the company on upgrading and operating the electric grid as well as expansion into newly covered areas.

Oncor is one of a handful of regulated Transmission and Distribution Utilities (TDUs) in the state of Texas, each of which holds a regional monopoly on the transmission of electricity which is bought by retail electricity providers such as TXU and Reliant and resold to consumers.

ONCOR doesn’t bill consumers directly.  The flat and usage based fees charged by Oncor for electric delivery are passed through to consumers on their electric bills which come from Retail Electricity Providers in Texas.

If the proposal is approved, a typical residential consumer would see their electricity rate go up about .5 cents per kWh.

2016 Another Strong Year for Renewable Energy and Natural Gas

2016 Renewable EnergyContinuing a 3 year trend, 2016 saw renewable energy account for the majority of new electricity generation capacity in the United States.  The lion’s share of these additions came in the form of wind and solar power.

As is often the case, renewable energy generation peaked in the spring on a nationwide basis.  The spring typically sees a peak in hydroelectric power in the western part of the U.S. as rain and snowmelt drives hydro power. The Western United States also contributed the majority of the country’s solar power with 77% of total U.S. solar generation.  In Texas, the state’s massive installed wind base continued to churn out electricity for the Texas electricity grid which is separate from the other major U.S. electricity grids.

While 2016 also saw a large increase in solar power, most new solar capacity comes from small scale solar photovoltaic rather than large scale utility generation.  As of October of 2016 the U.S had a total of 12.6 GW of small-scale solar power installed.

Wholesale Electricity Rates Continue to Fall

Despite the fact that new capacity generation is coming largely from renewable energy sources, it is cheap natural gas that continues to put downward pressure on electricity rates.  Monthly wholesale prices for 2016 were lower than 2015; driven largely by lower natural gas prices.  The cost of natural gas delivered to power generators was 17% lower for the first 10 months of 2016.

Low rates for natural gas also contributed to an increased reliance on natural gas for electricity generation.  2016 saw, first the first time, natural gas surpass coal for electricity nationwide.  Although, in Texas this has been the case for a number of years.

 

GM Continues Transition To Renewable Energy With Wind-Powered Arlington, Texas Plant

electric-car-plantGM has recently announced its latest milestone in its drive to increase its use of renewable energy to power its operations. The company last year completed a deal to purchase sufficient wind-generated energy to power its major plant in Arlington, as well as 15 other separate facilities, which includes GM’s financial headquarters located in the downtown area of Fort Worth.

The company stated that it has agreed to buy 50 megawatts of electricity produced at the Cactus Flats wind farm, a massive 150-megawatt farm that is under development near San Angelo by Renewable Energy Systems. The Cactus Flats wind farm is another major investment in wind energy in Texas, which is currently the largest producer of wind energy in the country with over 10,000 turbines currently in operation.

The plant in Arlington builds some of GM’s most iconic models, focusing on the company’s top-selling sport utility vehicles. The plant already receives 50% of its power from renewable sources of energy, and the addition of the Cactus Flats wind farm will result in the plant being powered completely by green energy sources. It is estimated that the shift to wind power will reduce the plant’s total energy costs by up to $3 million a year, as well as reduce carbon dioxide emissions by more than 1 million tons over the entirety of the contract.

GM’s Worldwide Targets for Renewable Energy Part of Climate Change Commitments

Beginning in 2018, GM will be sourcing over 193,000 megawatt hours of power per year from wind alone. At the beginning of the contract over 6% of GM’s worldwide energy use will be from renewable sources. This recent deal is just a small part of GM’s long-term commitment to being powered entirely by renewable sources by 2050. This goal was set alongside other similar climate change commitments, such as the development of vehicles powered by electricity.

Texas Sets Another Record For Wind Power

Texas Wind EnergyTexas has set a new record for electricity generated from wind.  On November 27th 2016, the ERCOT system saw more than 15,000 megawatts of electricity provided to the grid from wind turbines.

The amount represented about 45% of the spot demand for power in the grid in the afternoon.

“We saw high wind output throughout the day, ranging from just over 10,000 MW during the late night hours to this peak output during the noon hour,” said ERCOT Senior Director of System Operations Dan Woodfin. “Over the years, ERCOT has taken a number of steps, such as improving renewable generation forecasts, to allow us to operate the grid reliably on days like this.”

During the period, total output from wind approach the system capacity of 17,000 MW.

Electricity-Related Complaints Continue Downward Trend In Post-Deregulation Texas Market

ERCOTOver the last fiscal year Texans filed 4,835 electricity-related inquiries or complaints according to the Texas Coalition for Affordable Power. This represents a significant drop from the previous post-deregulation low set last year, where the Public Utility Commission registered 6,973 inquiries or complaints. Data from the PUC shows a drop across nine different categories of complaints, with only one category seeing an increase. The data from this year confirms the on-going trend of higher responsiveness and customer satisfaction in Texas’s deregulated retail energy market.

A Continuing Trend Based On Increased Customer Satisfaction

The almost 31% drop in electricity-related inquiries and complaints registered between 2015 and 2016 is the second largest drop so far recorded. Two of the main factors influencing this trend are lower energy prices and a growing familiarity with the conditions and providers of the deregulated market. Also, two major sources of complaints, Sharyland Utility and the installation of advanced meters, are no longer the source of as much dissatisfaction among customers.

The PUC registered a fall in almost every category of electricity-related complaints over the 2015 fiscal year. This falling rate of complaints includes a number of major categories of complaints, such as provision of service complaints, meter complaints and complaints related to switch-holds, the blocking of electric service for residences.

The data for 2015 suggests that customer satisfaction continues to see significant improvements across the state of Texas. The last three fiscal years in particular are registering increasing levels of customer satisfaction. While the data still shows a higher number of inquiries and complaints than pre-deregulation levels, the strong and on-going trend suggests that levels may soon approach their pre-deregulation lows.

Cheap Natural Gas Leads to Falling Consumer Electricity Rates

Plunging oil prices may have hit some energy companies hard and have some oil-producing nations worried about their budget deficits, but it has been a boon to the average American consumer as electricity rates have dropped 1% nationwide to an average of 12.4 cents per kilowatt hour, the first nationwide decline in energy prices in decades.

electricity_rates

As developed nations move away from burning dirty coal for energy as a result of the efforts to meet international greenhouse emission caps, cleaner burning natural gas plants and alternative energy sources (wind, sun, geothermal, etc) are filling in the gaps. Natural gas is now the major source of fuel for energy producing plants, and a 28% drop in the price of natural gas for energy producers over the first half of the year has translated into big gains for consumers nationwide.

However, the replacement of coal burning plants with plants that use natural gas and a plunging price in hydrocarbons is not the entire story. Solar and wind energy in particular continue to become more efficient with advancing technologies, and are taking an increasing share of national, and international, energy production. This year the United Kingdom produced more energy from solar panels than from burning coal, and marked the first day since 1882 that no energy was produced from the burning of coal across the entire nation.

The state of Texas has enjoyed an even greater drop in consumer electricity prices, down 6% to 11 cents per kilowatt hour, thanks to easy access to plentiful supplies of cheap natural gas and a deregulated market. The deregulated market has allowed producers to adjust their prices sooner to reflect the lower cost of natural gas, and then pass these savings on to the consumer.

New England, which has a similar share to Texas of energy produced by natural gas, saw a similar decline in electricity rates over the year. However, the biggest decline of 12% was observed in the state of Hawaii, which uses oil for the vast majority of its energy production. The steep decline in the price of oil helped to bring electricity rates down substantially, albeit from a position that was far above the national average as a result of the state’s remote location and the difficulties that its geography causes for the installation of energy infrastructure.

 

Amazon Comes To Texas For Electricity

Texas Wind EnergyAmazon.com has become the latest big company to turn to Texas serve their green energy needs.  They recently announced they will be building a huge wind farm in the state – their largest renewable energy project to date.  The 253 megawatt wind farm will be located in the West Texas county of Scurry.  Amazon has committed to buying 90% of the facilities output of electricity.  It will be capable of producing up to 1 million megawatt hours of electricity per year when it goes on line late next year.

Amazon’s Web Service cloud data centers (AWS) are large consumers of electricity.  Amazon has committed to a goal of 100% renewable energy.  The new wind farm in Texas will bring the company’s renewable energy portfolio up to 2.6 million MWh annually.  Amazon estimates that 40% of its AWS infrastructure will be powered by renewable energy by the end of the year.

Amazon is far from the only large company to go big on Texas electricity. Johnson & Johnson recently agreed to purchase half of the output of a 200 megawatt wind project being developed by EON SE in the Texas panhandle.  In 2013 Microsoft signed a 20 year deal to purchase all of the output of a 110 megawatt wind farm near Fort Worth developed by RES America.  Texas is also home to the largest federally owned wind farm which was built in 2014 to power the Pantex nuclear weapons facility.

Texas has paved the way for these large projects by investing billions of dollars in infrastructure to support what is by far the country’s largest installed wind capacity.   Texas has an independent electric grid and is the largest deregulated electricity market in the country.
