Wind and Solar Cross 10% U.S. Generation Share as Prices for Solar Keep Falling

June 19, 2017

Marking a significant milestone, power generation from the combined utility-scale and small-scale wind and solar installations in the U.S. surpassed 10% of the nation’s total power generation in March, according to the Energy Information Administration (EIA).

The news comes on the heels of an announcement last week by the Solar Energy Industries Association (SEIA) that installed system prices for solar systems have fallen across all market segments. Also for the first time, fixed-tilt utility-scale systems dipped under the $ 1/W barrier, SEIA said.

Breaking the Barrier—on a Gigawatt-Watt Level

The EIA said on June 14 that generation from wind and solar has grown steadily since 2007. On an annual basis, wind and solar generation made up 7% of total U.S. power generation in 2016.

The EIA noted that wind and solar follow seasonal patterns. Wind patterns vary based on geography. Wind generators in Texas and Oklahoma, for example, have their highest output in spring, while California generators see a boost in output in the summer.…

Analysis Shows U.S. Nuclear Plants Losing $2.9 Billion Annually

Increased use of less-expensive natural gas and renewable sources of energy for power generation is putting financial pressure on U.S. nuclear power plants, according to an analysis of electricity costs from Bloomberg New Energy Finance (BNEF).

Nicholas Steckler, an analyst for BNEF, in a June 14 report said nuclear operators are losing about $ 2.9 billion a year. Steckler said nuclear plants are being paid $ 20/MWh to $ 30/MWh for their electricity, while their generation costs an average of $ 35/MWh.

The report says 34 of 61 U.S. nuclear plants are in the red. Steckler specifically cited merchant nuclear plants owned by FirstEnergy Corp., Entergy Corp., and Exelon.

In a statement, Entergy said it would not comment on individual plants but said “financial challenges due to sustained wholesale power price declines and unfavorable market conditions” are affecting the profitability of its nuclear operations. The company said it is now concentrating on its regulated utility business. Entergy, along with its wholesale commodities division, owns seven U.S.…

$28 Million in DOE Funding Available for Advanced Energy Systems R&D

The Department of Energy (DOE) is offering approximately $ 28 million in cost-shared funding for research and development of advanced energy systems. According to three separate funding opportunity announcements (FOAs), the department is looking for research into advanced combustion systems, advanced turbines, and gasification.

“Advanced energy conversion systems are designed to enable efficient, low-cost, and near-zero emission energy from existing and new fossil fuel power plants,” a DOE release says.

University Turbine Systems Research

The University Turbine Systems Research (UTSR) program has available $ 5.15 million to fund laboratory/bench scale research and development projects in six technical topic areas:

Low-NOx combustion technology development for “air-breathing” advanced turbines
Advanced cooling technology development for “air-breathing” advanced turbines
Advanced materials technology development for “air-breathing” advanced turbines
Big data analytics
Advanced instrumentation
Pressure gain combustion

DOE anticipates awarding funding for six to nine projects. Up to three awards are expected in each of the first three topic areas, and one per topic in the last three areas.…

Proposed Wisconsin Gas-Fired Plant Would Aid Utilities’ Renewable Initiatives

Minnesota Power and Wisconsin’s Dairyland Power Cooperative announced plans to co-develop a combined cycle natural gas–fired power plant, a 550-MW facility designed to provide backup power for the utilities’ efforts to expand their use of renewable energy sources.

The Nemadji Trail Energy Center would be built along the Nemadji River in Superior, Wis., a location adjacent to both utilities’ service territories. The utilities would co-own the facility and divide its electrical power output. The companies said that if regulators approve the plan (a decision is expected sometime in 2018), construction could begin in 2020 and the $ 700-million plant—each company investing $ 350 million—could be operational in 2024 or 2025.

Minnesota Power spokeswoman Amy Rutledge said the Superior site’s access to existing natural gas and electric transmission lines made it a logical choice for the utilities. The area is served by multiple natural gas lines, including from Northern Natural Gas, Great Lakes Gas Transmission, and ANR Pipeline, according to analysts Rocco Canonica and Richard Frey of S&P Global and Platts Analytics.…

EPA Extends Deadline for 2015 Ozone NAAQS Area Designations

The Environmental Protection Agency (EPA) is giving states an extra year to develop air quality plans related to the 2015-National Ambient Air Quality Standards (NAAQS) for ground-level ozone.

In a June 6 letter sent to U.S. governors, EPA Administrator Scott Pruitt announced that the extended deadline for promulgating initial area designations for the rule issued by the Obama administration in October 2015 would give the agency more time to assess available information and complete its review of the rule.

When it promulgated the rule, which slashed the current limit of 75 parts per billion (ppb) to 70 ppb, former EPA Administrator Gina McCarthy said the decision was based on well-founded concerns for public health. States have begun submitting proposals for area designations under the new standard.

The Trump administration’s review of the rule is more focused on how it will affect businesses. According to the EPA, areas designated as being in “nonattainment” of the standard face consequences, including: “increased regulatory burdens, restrictions on infrastructure investment, and increased costs to businesses.”…

Kemper, Now Slated to Start in Late June, Will Need Costly Post In-Service Improvement Projects

Mississippi Power’s Kemper County integrated gasification combined cycle (IGCC) project is now expected to be in service by the end of June, but the company expects it will need post in-service improvements. It also said timing of when it will file a case to address the recovery of costs not currently reflected in rates is uncertain.

The Southern Co. subsidiary said on June 5 that it filed a rate plan with the Mississippi Public Service Commission (MPSC) that would allow current rates for recovery of portions of the Kemper project’s existing combined cycle gas turbine (CCGT) plant to remain in place. If approved, that filing will not increase customer bills, it said.

It added, however, that discussions with the MPSC continue on the status of the project and the nature and timing of a rate filing to address recovery of the remainder of the Kemper project costs, which includes its gasification component.

Mississippi Power wants a timely resolution of such a filing, which will likely require a settlement between the company and the Mississippi Public Utilities staff as well as other parties.…
