Natural Gas To Surpass Coal As Source Of CO2

Natural gas is expected to soon surpass coal as a source of CO2.  As natural gas continues to replace coal as a fuel for the production of electricity for the nation’s electric grids, the total amount of emissions coming from natural gas activity will pass that of coal in 2016.

Energy related CO2 emissions from natural gas are expected to exceed that of coal by 10% in 2016.  The total amount of electricity generated by natural gas reached record highs in the U.S. in July of 2016.  The nearly 5,000 gigawatts per day surpassed the previous record in 2015 by around 9%.  This was due partially to high temperatures as well as the continuing price advantage of natural gas over coal.  For the year, electricity from natural gas is expected to account for around 34% of power output compared to 30% for coal.

As ever tightening federal mandates force coal plants to either modernize or shut down, coal based electricity output has been in a multi-year down trend in the US.  This is expected to continue in the years to come. Much of this lost production has been replaced by renewable sources of power such as solar and wind.  The latter is particularly the case in Texas.

This all comes on top of another trend that has seen overall electricity sales declining thanks in part to greater energy efficiency in residential construction as well as federal energy efficiency mandates.  Lower peaks in electricity demand tend to favor cleaner sources of power. Coal and natural gas are considered more responsive sources of power generation and more likely to be ramped up in times of greater peak demand.

Electricity Rates

The gradual shift of electricity production away from coal and toward natural gas and renewable sources of power has not put upward pressure on electricity rates.  The national average for electricity for July 2016 was 13.0 cents per kwh.  By comparison, a 12 month electricity plan can be found for 6.3 cents per kwh in the Dallas, Texas area as of the time of this writing.

 

Coal’s Importance To Texas Electricity Continues To Decline

smokestackThe use of coal to generate electricity in Texas continues to slide.  Just ten years ago, half of the electricity in Texas came from the burning of coal.  Today, coal only contributes 20%.

Why the huge drop off?  The two main factors are natural gas and wind energy, with solar and hydro also playing a part.

Texas is by far the largest producer of natural gas in the U.S., more than doubling the production of the #2 state, Pennsylvania.  Texas is now producing so much natural gas, that a pipeline is being built that will send a significant amount of natural gas to Mexico to be used by their electricity generators.

Texas also produces more electricity via wind energy than any other state.  There have already been days when the state saw more electricity produced from wind than from coal.

It is expected that by 2020, more than half of all coal-burning power plants in Texas will be shuttered.

 

University of Texas-San Antonio Releases Report on Economic Impact of Eagle Ford Shale

In a report released by the University of Texas-San Antonio (UTSA) entitled “Economic Impact of the Eagle Ford Shale”, researchers from the Center for Community and Business Research at the University’s Institute for Economic Development found that extraction of oil, condensate, and natural gas from the Eagle Ford Shale in South Texas generated over $87 billion in total economic output for Texas in 2013, including $42.8 billion in gross regional product for the 21 counties involved in the study.

In 2013, shale activity from Eagle Ford provided over $4.4 billion to state and local governments and supported almost 155,000 jobs, and UTSA projected that over the next ten years, the industry will support as many as 196,660 full-time-equivalent jobs and generate more than $137 billion for the region, far exceeding the $89 billion originally projected for 2022 in last March’s report. UTSA explains that the upward adjustment was a result of a continued rise in production that has exceeded expectations, as well as growth in the development of support industries such as refineries, processing and ports, among others.

Production from the Eagle Ford Shale has grown exponentially; oil and condensate production rose from 581 barrels per day in 2008 to over 1.1 million barrels per day as of June 2014, and natural gas production puts up equally impressive numbers, at more than 4 billion cubic feet per day. The report covers 21 counties that benefit economically from development in the Eagle Ford Shale; in addition to the 15 most directly-involved counties, in which 3,311 wells were actively producing in 2013, there are six surrounding counties that have seen a boom in economic growth from the development of related service and support industries.

The forecast for continued healthy growth has attracted more capital investment to Eagle Ford than to any other shale field in the country. Robert McKinley, UTSA Associate VP for Economic Development, said the revenue would provide the ability to develop and improve infrastructure that would benefit rural communities, such as roads, schools, broadband internet, and medical facilities. The report cautions that these infrastructure improvements are vital to the sustainability of communities in the region and recommends that community leaders should actively partner with state legislators to ensure that those communities can get support from revenue sources such as the Economic Stabilization Fund and from allowable city and county taxes.

The report also recommends that area communities should consider aesthetics, as well, and perhaps attempt diversification in less industrial-feeling investments, like olive farming and olive oil production, tourism, and recreation, to keep their surroundings attractive and enjoyable. Keeping the needs of local residents in mind rather than just focusing on the very impressive numbers will ensure that stability and economic success are long-lasting not just for investors, but for the whole community.

Texas Clean Energy Coalition Report Provides Incentive For Renewable Energy

The clean energy advocacy group Texas Clean Energy Coalition (TCEC), in a new report entitled Exploring Natural Gas and Renewables in ERCOT II, Future Generation Scenarios for Texas, provides an in-depth analysis of the future energy supply prospects of the State of Texas, based on existing technology, with a realistic and somewhat conservative analysis. It is the first report of its kind, overshadowing previous somewhat simplistic modeling, and utilizing high-end modeling techniques and highly developed statistical analysis.

The study examines the current Texas electricity grid, based on the current power supply supplied through the Electric Reliability Council of Texas (ERCOT) —power grid. ERCOT manages electricity provided to 23 million Texas residents, supplying 85% of the state’s electric load. Varied energy sources are considered in the present grid, from coal-fired electric plants, electricity supplied by natural gas, as well as renewable energy’s current contribution to Texas power in the form of wind-powered electricity and solar energy.

Texas is already the state producing the most wind-powered electricity in the country, with more than 12,000 megawatts of current capacity, more than double that of any other state in the U.S.  40% of Texas’ electricity is currently produced from natural gas plants, while the state itself is the leading producer of natural gas in the United States. Additionally, the state of Texas has an abundance of natural sunlight all year round, which makes increased reliance on electricity through solar power both a reliable and economically advantageous proposition. Texas currently gets 10% of its energy from renewable sources, and the study suggests an increase in reliance on renewable resources prospectively reaching between 25% to 43% over the 20 year scope of the report.

Using various scenarios and models with major factors considered such as possible public environmental policy, the likelihood of a slight decrease in the cost of producing electricity through renewable sources, relative stability in the cost of natural gas vs. significantly higher prices for natural gas, and the required power reserve margin, the topic is examined not in the context of a “tree huggers” utopia, but realistically, and more importantly, in terms of costs and profits for power companies—how planning for the future, based on numerous likely scenarios and variables, may make investing in facilities for renewable resources along with an increase in reliance on natural gas powered plants, a strategy with long-term economic benefit for the state. The report, then, takes a pragmatic approach rather than taking on the tone of an environmental crusade.

A by-product of the report, is that it can provide incentive for policy makers who are interested in reducing reliance on “dirty” energy, such as supplied by coal powered plants, to pursue a stricter policy in reduction of carbon emissions, with a resultant increase in reliance on wind, solar and natural gas. Such an incentive for policy makers is not directly insisted on by the report, but it could be a beneficial by-product, in that a stricter policies on carbon emissions, one of the scenarios explored here, while perhaps making coal-fired plants less profitable, or in the strictest scenario, making them unprofitable and essentially forcing coal-operated plants closed, would not necessarily result in higher energy prices or loss of profit as a whole to the industry. With planning, low-cost energy could be maintained with clean energy supplies, alongside a stable profit margin for power producers, by investing more heavily in renewable energy resources, alongside an increase in reliance on the clean energy produced by natural gas fired power plants.

Through the study all involved can take a realistic look at the next 20 years of increasing energy needs in Texas, and while the study does not focus on environmental benefits, the thrust of the report is that there are both economic benefits to a greater investment in renewable energy and gas, with the implied side benefit of less impact on the environment (less pollution). If power companies can maintain profits while saving the environment, why not? It is a win-win situation for everyone involved. This is especially poignant in view of the fact that Texas’ energy requirements are expected to double over this same 20 year time period, placing a tremendous demand on existing resources. The topic of how to meet future energy demands is something that needs to be addressed regardless of the one’s environmental position, so the question becomes, simply, which direction to point the arrow. The report implies that pointing in the direction of clean energy makes economic sense for everyone involved by adequately covering a wide range of possible scenarios including future technological developments.

Natural Gas Exports Mean Likely Higher Electricity Rates in Texas

A decade ago the idea of exporting natural gas from the U.S. would have been unthinkable.   Now energy companies are lobbying federal regulators hard to get permission to sell cheap U.S. natural gas to overseas markets.  A facility in Freeport, Texas becomes one of the first to receive conditional approval from the Energy Department to begin exporting liquefied natural gas (LNG).

The controversial practice of natural gas fracking has lead to a paradigm shift in U.S energy policy.   New drilling techniques have resulted in a surge in natural gas production in the U.S.  But energy producers have become so good at extracting natural gas from the ground they are no longer able to get a premium price for their product in the U.S. 

The supply of natural gas relative to the demand makes it a much less precious community than in yeas past.  Prices have fallen dramatically.  The solution according to many is to begin exporting U.S natural gas to foreign markets where natural gas trades at much higher prices.

There are major political and financial hurtles that have to be cleared, however, before exporting can begin.  Exporting natural gas requires approval from the Energy Department.  The Department must determine that the project is in the best interest of the country.  In total there are around 20 applications pending to begin exporting.

Exporting natural gas is a capital intensive undertaking.  In order to ship natural gas it must be cooled to liquid form (liquefied natural gas) and loaded onto large vessels for shipping.  This necessitates infrastructure and large facilities; all of which means lots of money.

The Freeport facility can likely be up and running sooner than other projects because, ironically, it was originally built by Dow Chemical and several other partners as a LNG import facility.   This was at a time when natural gas prices were much higher and there were concerns about having enough natural gas in the U.S to meet domestic demand.  A consortium of investors will now be retooling the facility to ship LNG out of the country.

To the Texas consumer, this development is a mixed bag.  Energy is a large part of the Texas economy. What is good for the energy industry is generally good for the state.  However, once natural gas exports begin, it will almost certainly mean higher prices.  Since Texas electricity rates a driven in large part by the price of natural gas, electric rates will almost certainly go up.   This would first be reflected in the wholesale electricity market and ultimately be passed on to consumers by electricity providers.

Was The Dallas Earthquake Caused By Natural Gas Fracking?

According to a scientist with the University of Texas at Austin’s Institute for Geophysics, the magnitude 3.4 earthquake and related aftershocks felt in the Dallas area on Saturday, September 29th, 2012 were caused by the storage of wastewater from hydraulic fracturing (fracking) of natural gas.

Fracking involves pumping large amounts of water, sand, and chemicals into the ground to break up shale rock formations and free up long trapped natural gas.  This process results in large quantities of wastewater that must be deal with.  One common method of dealing with wastewater is pumping it deep underground into large reservoirs.

One such wastewater injection well was opened on an area of land just south of DFW airport in 2007.  According to the scientist, the DFW area has since experienced multiple earthquakes of greater than 3.0 magnitude.  This is despite the fact that the area had never recorded a single earthquake of that size prior to 2008.

The Good with The Bad

Dallas electricity rates, like the rest ofTexas, have been the cheapest rates seen in a number of years.  This is due largely to the natural gas boom in the state.  A large portion ofTexas electricity is generated from natural gas.  The increase in natural gas production has meant cheap natural gas prices.  This has lead to cheap electricity.

The link between fracking and earthquakes is not new.    A study recently published in the journal Proceedings of the National Academy of Sciences found that 24 earthquakes over a 2 year period from 2009 to 2011 in the area of the Texas Barnette Shale formation had epicenters within 2 miles of one or more wastewater injection wells.   

Saturday’s earthquake was felt in parts of Irving, Grand Prairie, Hurst, and the DFW area.  It prompted a number of 911 calls but resulted in no reported injuries.

New Plant To Bring Electricity And Jobs To Central Texas

Panda Power Funds announced obtained financing to construct a massive new natural gas-burning power plant in Temple, Texas.  The 758 megawatt combined-cycle power plant will generate enough electricity to power over 750,000 homes in Central and North Texas.   The plant will be located on a 250-acre site at the South Temple Industrial Park.

Environmental Considerations

The company claims that the new plant will be built using environmentally friendly technology and, when completed, will be one of the cleanest burning plants in the nation.  It will also maximize the use of reclaimed water to conserve the state’s fresh water. This is an important consideration in a state that has battled drought for quite some time now.

Jobs and Economic Impact

According to the company’s numbers the construction project will employ 700-800 workers at its peak.  Once completed, the plant will employ around 70 people to maintain ongoing operations and is projected to contribute over $1.6 billion to the Central Texas economy over the next 10 years.

More Power Plants Needed

The state has suffered from lack of new electricity generating capacity over the past few years, creating a great deal of concern over the ability of the Texas grid to keep up with anticipated demand over the next several years.  The decline in natural gas prices has been good news for consumers paying Texas electricity rates over the past several years, but has been a headache for electricity producers.  Because of the difficulty of making money in such an environment of cheap electricity, most producers have simply stopped building new plants in Texas.

The new plant in Temple, though a welcomed sight, will not be enough to solve the state’s electricity shortage.  It is expected to be completed in 2014.
