FOLSOM, Calif., Nov. 24, 2020 /PRNewswire/ — Trimark Associates, Inc. announces the deployment of an Aggregating Remote Terminal Unit (RTU) as a solution for remote, real-time telemetry with Independent System Operators (ISOs) and electric utilities. A milestone collaborative effort, the Aggregating RTU allows site owners to report operational data to ISOs and utilities, without installing dedicated on-site hardware.

A bit of background: Trimark has a partnership with AES Distributed Energy to function as their primary technology platform provider for their portfolio of new generating facilities. AES DE is developing a number of sites in the northeastern United States; significant portions of this region’s electrical grid are operated by ISO New England (ISO-NE), while National Grid serves as the primary utility in Massachusetts, Rhode Island, and large portions of New York State.

Similar to CAISO and IOUs in California, these entities have unique requirements regarding the collection of on-site data. Specifically, ISO-NE and National Grid both require that new generating facilities provide real-time telemetry to their Master Control Centers (MCCs) and Manager Control Centers (also ‘MCCs’), respectively. Both ISO-NE and National Grid informed AES of this mandate, and AES tasked Trimark with providing a solution.

Because of the large number of sites, this revelation made for an interesting challenge. While Trimark’s field techs routinely install gateways at utility-scale sites for telemetry and SCADA/DAS, the logistics of doing so for dozens of sites – including travel, setup, and testing – would have been tedious for everyone involved.

However, after a number of collaborative discussions, a promising solution emerged. Through discussions with the New York ISO (NYISO) and AES DE, Trimark learned of an alternate approach, aptly referred to by the ISO as a “Remote RTU.” This is a single RTU at a location remote from the site, which collects data from multiple sites. This eliminates the need for physical boxes at each site. Appreciating the flexibility it afforded, Trimark explored this option in earnest.

Soon thereafter, Trimark began developing our version of a Remote RTU, referring to it as an “Aggregating RTU” (ARTU). Essentially, the ARTU is a data gateway in the server room at Trimark’s Folsom, California headquarters. Managed by Trimark’s IT experts, the ARTU hosts multiple virtual machines for AES DE’s site data, which is reported to the ARTU via ISP connections. The ARTU sports a single, dedicated high-speed ISO connection for both the ISO and National Grid. The high-speed link is hardwired, but a secondary wireless connection serves as a backup.

Trimark tested this setup with NYISO, and it yielded stellar results. AES DE requested permission to use this approach with National Grid soon thereafter. Both companies, as well as ISO-NE, gave Trimark the green light to utilize the Aggregating RTU at AES DE’s New England-based sites. The first of these sites to employ this solution was AES DE’s PV installation at the University of Rhode Island, where a Trimark Data Acquisition System (DAS) was already installed. The integration went smoothly; since then, Trimark has expanded the Aggregating RTU’s capability, including implementing additional virtual machines for National Grid.

Given the successful application and tests of the Aggregating RTU, Trimark is excited to make wider use of the technology. The Trimark team believes it will prove popular with customers, particularly from a cost perspective. It eliminates the need for additional hardware, as well as an installation trip; thus, the Aggregating option saves customers thousands of dollars per site. Moreover, because there is one less device to worry about, customers will also see reduced maintenance costs over the lifetime of their site—and fewer headaches.

On top of that, the Aggregating RTU will also streamline the process of achieving Commercial Operation. From a scheduling perspective, eliminating the need to coordinate a site visit, install the appropriate telemetry hardware, and perform on-site testing significantly reduces any road bumps on the way to reaching COD. This helps ensure that customer sites are up and running when they need to be, without any loss of functionality or reliability.

“With the Aggregating RTU, there’s so much potential for cost savings and added efficiency,” says Jae Kim, Vice President of Operations at Trimark. “We can’t wait to leverage it in more projects, for more clients.”

In addition to the 50 MW project, Dakota Power Partners has proposed developing at least five more utility-scale solar facilities across the Garden State.

Dakota Power Partners, which said it intends to invest $1 billion in utility-scale solar in New Jersey, has won approval for the developer’s first solar farm as part of what could become a large project portfolio.

The Millville Planning Board unanimously approved the 50 MW solar farm during its monthly meeting on January 12, clearing the way for construction to begin by year’s end. Called Nabb Solar I, the project will be located in western Millville and is anticipated to begin operation in fall 2022.

Timothy Daniels, Dakota’s principal and co-founder, said the local officials were “quick to see the value of this project.”

Over the 30-year expected life of the project, Nabb Solar I is estimated to generate a total of approximately $7.8 million in taxes. Dakota said it will pay annual real estate taxes of approximately $102,295 to the City of Millville, $67,547 to Millville Public Schools, and $98,166 to Cumberland County, for a total of $268,008 in local taxes per year.

Joe Derella, director of the Cumberland County Board of Commissioners, called the project a “massive $70 million investment in our region” that will create hundreds of jobs.

“This is what the future of energy looks like in New Jersey,” said Millville Mayor Mike Santiago.

Nabb Solar I is one of six similar New Jersey projects being proposed by Dakota Power Partners, which has offices in Millville and Denver, Colorado. In total, Dakota is proposing a $1 billion utility-scale solar investment in the Garden State.

Utilizing a portfolio of utility-scale solar and solar+storage projects across the state, the company said it intends to achieve generating capacity totaling more than 1 GW in New Jersey.

According Dakota, the company has participated in the development of more than 3.15 GW of operating and in-construction wind and solar projects around the U.S., representing an aggregate capital investment in rural communities in excess of $3.8 billion.

The U.S. Department of Energy’s (DOE) Oak Ridge National Laboratory is partnering with Ohio’s Youngstown State University on a $1 million project to advance workforce development for the battery manufacturing industry.

According to the DOE, the new Energy Storage Workforce Innovation Center will serve as a training center based in the Midwest. It will support the battery and electric vehicle (EV) manufacturing industry in the northeast region of Ohio–referred to as “Voltage Valley” due to the EV sector’s regional investments–by helping supply a capable workforce.

The DOE said the U.S. is in a period of “tremendous advancement in battery technologies, presenting new opportunities for electric vehicles and energy storage systems,” and it’s essential to “prepare a workforce that will lead the next generation of energy storage technologies into practice.”

This effort supports the DOE’s Energy Storage Grand Challenge, which draws on the research capabilities of the U.S. national laboratories, universities, and industry to accelerate the development of energy storage technologies. The DOE added that the Energy Storage Grand Challenge Roadmap outlines a department-wide strategy to accelerate innovation across a range of storage technologies and develop a skilled workforce based on three concepts: Innovate Here, Make Here, and Deploy Everywhere.

U.S. Rep. Tim Ryan, representing Ohio’s 13th District, called this new partnership a “great example of how government can work to bolster efforts on the ground in our community to dominate in the clean energy economy.”

The $1 million project is sponsored by the DOE’s Office of Energy Efficiency and Renewable Energy’s Vehicle Technologies Office and the Advanced Manufacturing Office.

Drought conditions could impact power generation in the West

Avatar

Published

Ongoing drought and low snowpack mean that hydro production at two big dams could be impacted, affecting the West’s power supply in 2021.

Ongoing drought in parts of the West could trigger water conservation measures across seven states this year.

It would mark the first time that cutbacks outlined in drought contingency plans drafted two years ago have been put in place.

Everything from hydroelectric power generation to agricultural production to the bubbling fountains at Las Vegas casinos could be impacted.

Impacts on hydro generation could have ripple effects across the Southwest, including solar and energy storage.

A forecast released in mid-January by the U.S. Bureau of Reclamation said that the federally owned Lake Mead and Lake Powell — the nation’s two largest reservoirs and critical storage for Colorado River water and its 40 million users — are both approaching near-record-low levels. If those levels continue dropping as expected, agreements signed by the seven Colorado River Basin states in 2019 will go into effect, with water deliveries curtailed to keep the federal government from stepping in and imposing cuts of its own.

The Upper Colorado River basin region includes all or parts of Arizona, Colorado, Idaho, Nevada, New Mexico, Texas, Utah, and Wyoming. Drought has been an ongoing problem across much of the region for most of the century. The Bureau of Reclamation’s latest quarterly report showed Lake Powell at 42% of capacity and Lake Mead at 40%.

Three hydro plants that could be affected as water levels fall are the 1,312 MW station built at Glen Canyon Dam in 1964, and two hydro plants at Hoover Dam, which were built in 1936 and have a combined capacity of 2,078 MW.

In 2019, the Glen Canyon station generated nearly 4 million MWh of electricity. Combined, the two Hoover Dam stations generated roughly 3.4 million MWh, according to S&P Global.

The Bureau of Reclamation said in its report that during the 21-year period from 2000 to 2020, inflow to Lake Powell, which is a good measure of hydrologic conditions in the Colorado River Basin, was above average in only four of the past 19 years. It said the period 2000-2020 was the lowest 21-year period since the closure of Glen Canyon Dam in 1963.

The report said that under the current most probable forecast, the total water-year 2021 inflow to Lake Powell would be 5.72 million acre-feet, or roughly 53% of average.

If worst-case projections materialize, the water level at Lake Powell could drop below a critical level — measured as 3,525 feet above sea level — in early 2022, threatening the ability of Glen Canyon Dam to generate electricity.

The manufacturer reached its target with the help of a 70 MW virtual power purchase agreement with a Texas solar project.

The Clorox Co., whose products help consumers clean their homes and businesses, has turned to renewables to help clean the environment.

In an announcement, Clorox said it has reached its goal to power the company’s U.S. and Canadian operations using 100% renewable electricity. Part of the corporation’s environmental, social, and governance commitments, the target was achieved four years earlier than originally planned, thanks, in large part, to a solar contract.

In 2019, Clorox signed a 12-year virtual power purchase agreement (VPPA) to buy 70 MW annually from Enel Green Power’s Roadrunner solar project in Texas. Enel kicked off construction on the 497 MW Roadrunner facility in 2019 and completed the two-phase project in late 2020, making it one of the largest solar plants in the Lone Star State.

Moving forward, Clorox will maintain its 100% renewable electricity goal through the VPPA and other market purchases of renewable energy credits. Schneider Electric Energy & Sustainability Services advised the company on the deals.

Ed Huber, Clorox’s chief sustainability officer, said the manufacturer feels “a sense of urgency to address climate change” and recognizes “businesses play an important role in driving needed progress.”

Clorox also joined a coalition of other corporations–including Amazon, McDonalds, Pepsi Co., Walmart, and Facebook–calling on the Biden Administration to help pave the way for a zero-carbon U.S. power sector.
