CPS develops $10M battery to store renewable power

2.26.17

San Antonio-based CPS Energy is working on a project that, if successful, will help solve one of its trickiest problems in solar and wind energy production.

The public utility won a $3 million grant from the Texas Commission on Environmental Quality to develop a commercial battery to store large amounts of solar and wind power during peak production, which generally isn’t when people need it the most.

Renewable energy production can be fickle and unpredictable since it relies on the weather. Peak usage in Texas, on the other hand, is almost always in the evenings when people get home and turn on the air conditioning. The trouble with using wind and solar energy is shifting the power produced during the day and at night to peak usage times.

Report Shows New Transmission Can Help Wind Energy Supply a Third of U.S. Electricity

1.9.17

The Energy Department today released a report which confirms that adding even limited electricity transmission can significantly reduce the costs of expanding wind energy to supply 35% of U.S. electricity by 2050. The report, titled Reducing Wind Curtailment through Transmission Expansion in a Wind Vision Future and authored by the National Renewable Energy Laboratory (NREL), affirms the findings of the Energy Department’s 2015 Wind Vision, which showed that a future in which wind provides 20% of U.S. electricity in 2030 and 35% in 2050 is achievable and would provide significant economic, energy security, and health benefits to the nation.
For the study, NREL simulated operation of the electric power grid under a scenario where 35% of electricity comes from wind in the year 2050 using PLEXOS, an integrated modeling tool commonly used by utilities and transmission organizations. The study focuses on the Western Interconnection grid, which includes 11 states, two Canadian provinces, and parts of northern Mexico where the U.S. grid crosses the border. The study includes a baseline scenario assuming no significant transmission expansion across the western grid, as well as three scenarios with varying levels of transmission buildout.

Public Citizen Tom “Smitty” Smith Looks Back on a Life Well Lived

12.16.16

The appearance of Public Citizen Execu­tive Director Tom Smith at the November meeting of the Lone Star Chapter of the Sierra Club was not unusual in form. The man known universally as "Smitty" schmoozed with the group in the crowded back room of Scholz Garten, waited through the regular meeting business, and eventually walked to the speaker's platform to deliver a talk on the latest Texas and Austin developments in renewable energy. Smitty recalled, "the first time I ever lobbied ... with a bunch of Sierrans defending Barton Springs from balls of goo," and at least a few people in the room also recalled that battle.

"We're winning the war on coal," Smitty began, introducing the latest Public Citizen report on energy production in Texas, citing research that represented not only the environmental advantages of wind and solar, but the growing economic muscle of the once "alternative" energy resources. We've reached "the beginning of the end" of reliance on coal and other fossil fuels, he continued, noting the persistently low natural gas prices that have undermined the market logic of coal, the growth of wind resources, and his expectation that 12 of the 19 existing Texas coal plants will be retired by 2022, with the solar industry now the 26th largest in Texas.

Here in Austin, Smitty continued, the eventual closure of the coal-fired Fayette Power Plant has become imminent, not only because of its environmental consequences, but because his research reflects that Fayette is now losing about $30 million a year. (Austin Energy owns a one-third interest in Fayette.)

Moreover, the city of Austin has become increasingly committed to reducing its carbon emissions, with updated Resource, Generation, and Climate Protection Plans intended to reduce carbon emissions to zero by 2030. Smitty also delivered a thumbnail history of the Texas environmental movement – against nukes, to protect local resources, and to fight climate change – and he credited his audience for providing the activist legwork. All of this was possible, he told the Sierrans, "because of the organizing we did in Austin and Texas."

It was vintage Smitty: the casual manner and good humor; the bar graphs reflecting resource and economic analysis, energy analytics combined with political commentary. Most especially, the optimism – the absolute conviction that with enough public spirit and hard work, all things are possible.

TREIA President Melissa Miller: Keynote Speaker at Oil + Renewables-What Alberta Can Learn From Texas

11.17.16

Texas is an oil-producing state with a deregulated electricity market. Alberta is an oil-producing province with a deregulated electricity market. However, Texas is well ahead of Alberta when it comes to embracing the renewable energy revolution. 
It has the most wind energy installed out of any state in the nation. In March of this year wind energy provided 48 per cent of Texas' electricity needs. Just in August of this year almost 300 megawatts of utility scale solar was installed and in 2017 and there is more than 1800 megawatts of utility scale solar in the queue, ready to go. 
Renewable energy is not a red or blue partisan issue in Texas. It is business. And Alberta has a lot we can learn from our southern cousins. So how did this oil producing state with a conservative streak end up being a renewable energy leader? That's why Progress Alberta brought up Melissa Miller, president of the Texas Renewable Energy Industries Alliance to speak.

NREL 2016 Standard Scenarios Outlook Shows Continued Growth in Renewables and Gas in the U.S. Power Sector

11.16.16

The Energy Department's National Renewable Energy Laboratory (NREL) has released the 2016 Standard Scenarios: A U.S. Electricity Sector Outlook. The outlook shows significant projected growth in natural gas and renewables through 2050 driven by abundant, low-cost natural gas and renewable energy cost declines and performance improvements. The Standard Scenarios are designed to capture a range of possible futures across a variety of factors that could impact power sector evolution. 
The report discusses four areas of recent and projected future change in the U.S. electricity sector: renewable energy cost declines and associated growth, abundance of low-cost natural gas and associated generation, rapid growth in distributed rooftop photovoltaics (PV), and power sector decarbonization. New to this year's report is the Standard Scenarios Scenario Viewer, which provides downloadable state-level capacity, generation, and other results for the scenarios included in the report.
 "We are excited to share not just an outlook that explores power sector evolution--but also the underlying scenario data we used to create that outlook," said NREL Analyst and Project Lead Wesley Cole. "The scenario data can be used by others to inform their own independent analysis while still drawing on the modeling and expertise used to create the scenarios."
Now in its second year, the Standard Scenarios consist of 18 power sector scenarios, which have been projected using NREL's Regional Energy Deployment System (ReEDS) long-term capacity expansion model and the dGen rooftop PV diffusion model. The purpose of the Standard Scenarios output data and the associated report is to provide data, context, and discussion to inform stakeholder analysis and decisions that can impact the future direction of the U.S. power sector. The work is supported by the Energy Department's Office of Energy Efficiency and Renewable Energy.

Texas Renewable Industry Unfazed by Trump Environmental Policies

11.13.16

By Tom Kleckner

GEORGETOWN, Texas — Preston Schultz, director of development for Chicago-based Hecate Energy, says his firm is named after the three-faced Greek goddess of the crossroads. “She’s also the goddess of black magic,” he said, “but we don’t talk about that so much.”

It’s an apt enough description for where the renewables industry finds itself following last week’s election of climate skeptic Donald Trump as president of the United States: at the crossroads, and possibly needing a little magic to build upon its recent progress.

Trump, who has promised to scrap the Clean Power Plan and withdraw the U.S. from the Paris Agreement, has shown little affection for renewables but promised to “save” the coal industry and reduce restrictions on natural gas production.
