Germany's Solar Energy Output Surpasses Nuclear Generation in July

PV Magazine: Germany Breaks Record Wind and PV Generation in July


According to Fraunhofer ISE’s data, the amount of PV and wind generated electricity fed into the grid hit a record high in July in Germany. The PV power generated also matched up to nuclear. Another first.


July 2015 became a record month for the combined efforts of PV and wind energy. Both renewable sources managed to churn out more electricity than ever before as the statistics show.


According to the Fraunhofer ISE, 11.7TWh of renewable electricity was produced in July and this number surpasses the previous highs in January and March this year.


Bloomberg: Why Power Suppliers Most Affected by EPA Plan Don’t Hate It


Opponents of President Barack Obama’s plan to cut power-plant emissions say utilities will be among the casualties. You wouldn’t know it to hear from the power providers themselves.


For a group that must dramatically alter the way it does business to comply with the proposal, utilities don’t sound very annoyed. In fact, the industry’s main trade group said the Obama administration “seems to have responded to some of our key concerns.” The new rules will even boost profits for some.


MIT Technology Review: Smart Windows Just Got Cooler


Window glass that can tint on demand is pretty slick, but a new advancement has made it even cooler — and that could help the technology finally go mainstream.


Smart glass has been around for decades, but it is quite pricey and has found only niche applications, such as the windows of a new Boeing jetliner. But a new kind of electrochromic window glass, which changes color in response to the addition or removal of electronic charge, is more versatile than the technology now on the market, and it could be cheaper, too.


Wall Street Journal: Tesla Executive Presses Auto Makers on Electrification


Tesla Motors Inc. came to a conference here with a tough message for other auto makers: stop building compliance cars.


An executive at the Silicon Valley electric-car maker on Tuesday bemoaned the inability of General Motors Co. and other manufacturers to have better success selling their own battery-powered vehicles.


Instead, most other auto makers are producing electric cars to meet minimum regulatory standards while continuing to build and sell less-efficient gas-engine vehicles in droves, said Diarmuid O’Connell, Tesla’s vice president of business development.


Fuel Freedom: What Caused EV Sales to Drop Off a Cliff in July?


The website Inside EVs, which keeps track of monthly sales for all-electrics and plug-in hybrids in the U.S. and globally, has published its July numbers, and they’re abysmal: Only 7,102 were sold during the month, compared with 11,242 in July 2014.


There are still six models for which numbers are not available — Ford’s Fusion Energi, C-Max Energi and Focus Electric; Porsche Cayenne S-E and Panamera S-E; and the Kia Soul EV — but even if those cars come in at the same level as this June, the overall sales tally will still be well under last year’s pace.


For the first six months of 2015, a total of 61,449 EVs have been sold domestically, compared with 123,049 during the same period last year. Meantime, the rest of the world continues to outsell the U.S., thanks in part to generous subsidies in many European countries.

Texas Hits New Peak Wind Output


Graph of Texas (ERCOT) hourly wind generation, as explained in the article text


At 8:48 p.m. on March 26, wind generation on the electric grid covering most of the state of Texas reached a new instantaneous peak output of 10,296 megawatts (MW). At that moment, wind supplied almost 29% of total electricity load, according to the Electric Reliability Council of Texas (ERCOT), the grid’s operator. The average wind production in that hour was 10,120 MW. The new wind record surpassed two highs reached in the previous week, while the record prior to March was 9,674 MW set in May 2013.


March’s wind power record will likely be surpassed in the near future as wind capacity continues to be added in the state. Texas currently has more than 12,000 MW of operational utility-scale wind capacity (see graph below)—about one-fifth of the total wind capacity in the United States. According to preliminary data from the U.S. Energy Information Administration’s Electric Power Monthly, Texas added 150 MW of utility-scale wind capacity in 2013, less than one-tenth of the nearly 1,600 MW added in the previous year.


Graph of total utility-scale wind capacity in Texas, as explained in the article text


The significant slowdown in wind additions in 2013 mirrored the national trend, which reflected the lapse of the federal production tax credit (PTC) at the end of 2012. That lapse encouraged those with facilities under construction to complete them and begin operation before the end of 2012 in order to receive the tax credits (which are for all generation during the first 10 years of operation). The subsequent one-year extension in early 2013 required only that plants commence construction in 2013 to be eligible to receive the tax credits after the start of operations at a later date. This modification of eligibility requirements led to many wind projects beginning construction in 2013 with expected completion dates in 2014-15. Trade association reports estimate that there were more than 7,000 MW of wind projects under construction in Texas at the end of 2013; however, exactly how much of that capacity will actually be completed and by when remains to be seen.


The recent wind output records are a result not only of the growing amount of wind capacity in the state, but also of the successful completion of a major state-directed transmission expansion program, the Competitive Renewable Energy Zones (CREZ) program, which was specifically designed to allow wind power to reach a wider swath of the ERCOT grid and reduce grid congestion-related curtailments of wind power. Tomorrow’s article will discuss wind curtailments and the CREZ program in more detail.
