25 of the over 50 Schools and Educational Institutions (ITIS, IPSIA, Licei, CFP and Higher Technical Institutes - ITS) enrolled in the 2021 Automation Olympics, coming from 18 regions, concluded the path that led them to the final - which was carried out entirely online.

The competition organized every year by Siemens SCE (Siemens Automation Cooperates with Education) and recognized by MIUR in the national program for the enhancement of excellence, has seen a hybrid edition this year.

"Taking into account that this year most of the laboratories, where one can plan one's real case as a group, have been closed due to the pandemic, we have provided the possibility for students to deliver even a simulated project" said Raffaella Menconi , Head of Siemens SCE in Italy.

The response of the schools, however, was to prepare a real project anyway, also interfacing with local companies, which have not supported the only for the identification of design ideas, but also for the research of materials and above all for a targeted training.

A further demonstration of the fact that a strong synergy with the company.

The projects largely respond to the spirit that embodies Industry 4.0 since they come from a joint work of classes from different addresses or from different schools and are the result of an integration of various technologies (plc , inverters, motors, IoT and simulation solutions, motion and cloud management systems). There are also those (IIS Galilei Artiglio Viareggio) who thought of having a neural network trained by students interact with a Siemens plc.

The jury of Siemens technicians, after having supervised the 25 projects in the competition, decided the eight winners: the first 3 institutes among the Seniors and the first 5 among the Juniors, to which are added the Special Communication Award and the brand new "Learning Agility" award reserved for the Teacher who most distinguished himself for his agility "by developing the skills of a true Educational Leader, promoting a collaborative climate in the work team, motivating and involving human resources in the best possible way and managing those instruments available ”commented Menconi.

First place in the Junior category, Apro TECH scarl of Alba with the "Wine process automation" project, a real application capable of responding to a business need. In second position the ITIS MMMilano of Polistena (RC) with the "Factor 4.0" project while the third classified is the IPSIA G. Ceconi of Udine with the "Smart charger" project.

The IIS Galilei-Artiglio of Viareggio conquered the podium in the Senior category which, with the "PVCorobot" project, distinguished itself for innovation and the development potential of the new technologies used, such as artificial intelligence.

Equal merit, second place in the Senior category, the IIS Corni di Modena with the "machine sample cutters for tests in the production of wood panels "and the ITIS A. Volta of Alessandria with the project" Jigsawlver ".

The latter institute also wins the Communication Award, demonstrating how important it is also to know present good ideas well, as well as the doc award “Learning Agility” body.





Battery storage as peaking capacity: How Alamitos changed the game for California

Commissioned at the start of this year, the Alamitos Battery Energy Storage System in California is a landmark project for the industry in having competed against natural gas to provide peaking capacity for the grid. Andy Colthorpe finds out the project’s backstory from Fluence’s Ray Hohenstein and AES’ Mark Miller. This is a short extract of an article which originally appeared in Vol.27 of PV Tech Power, our quarterly journal and can be found in the Storage & Smart Power section contributed to each edition by the team at Energy-Storage.news. 


When it was first proposed in 2014, at 100MW / 400MWh, Alamitos Battery Energy Storage System was the world’s biggest contracted battery project. By the time it came online as scheduled on 1 January 2021 — after a construction period which began in 2019 — it could no longer take that crown, although it is certainly still one of the biggest around.


However, Alamitos was and remains historic for another, arguably even more significant reason. It represents the first time that battery storage has directly come up against natural gas in a competitive solicitation process and won. California investor-owned utility (IOU) Southern California Edison (SCE) picked out the plan designed by power producer AES Corporation as a means of providing essential local capacity following the shutdown of the San Ofre nuclear power plant (see timeline, p.92).


The utility put out an all-source procurement to find 2,200MW of capacity to replace San Ofre’s in its energy mix and from a minimum expectation that about 50MW of that would come from battery storage, SCE actually made 235MW of awards. Alongside 135MW of behind-the-meter energy storage, AES Corporation’s front-of-meter Alamitos project won out.


The big caveat perhaps is that Alamitos’ battery storage will be flanked by two new natural gas plants. These are combined cycle gas turbine (CCGT) plants which provide baseload capacity. As such they are the more efficient and less emissions-intensive cousins of open cycle gas turbines which are commonly used as peaker plants. The CCGTs AES is building at the sites however have a lower emissions profile again and are also 70% less water-intensive than legacy CCGTs and frankly, at this stage, it’s a difficult truth that rapidly deploying energy capacity cost-effectively to meet the shortfall created by San Ofre’s demise would be extremely challenging without these plants.


Nonetheless, the arrival of Alamitos Battery Energy Storage System (BESS), reduces the need for gas peaker plants in the Greater Los Angeles area: as you probably already know, gas peaker plants may have been the cheapest option to deploy when most of them were built in the 1960s and 1970s, but are expensive to run and typically only go into action very infrequently.


Many peaker plants have a capacity factor of 15% or below. When they are called into action, they are also extremely polluting and due to their need to match peak demand are often in or close to heavily populated areas. Put simply, the BESS at Alamitos will charge at off-peak times and at times of high solar generation and then discharge for up to four hours to meet local energy demand on the grid at peak times.


Back in 2014, after several years of developing and building battery storage projects around the world of about 5MW to 10MW each, AES Corporation wanted to propose, alongside the two CCGT plants, a showcase of large-scale battery storage as “very capable and competitive technology against open cycle gas,” Mark Miller, AES’ market business leader for California, says.


“When you look back on it, that’s almost seven years ago. It’s an extraordinary decision, not only by AES to table that and show the confidence in our technology, but even more so to think about what Southern California Edison did in awarding that 100MW, four-hour duration product as a direct competitor to natural gas. We showed that four-hour duration, on a cost basis, was directly competitive with natural gas, so hats off to SCE to actually take that bold step and give us a 20-year power purchase agreement (PPA). From that perspective, it was a very unique opportunity and kind of showed the merits of not only our confidence in technology, but also the ability to deliver.”


From a bold decision and a step-change in the understanding of what emissions-free battery technology can do, now that the system has gone into operation, this year will be pivotal in proving the value of batteries to the grid. The California Independent System Operator (CAISO), has said that it expects the amount of battery storage on its transmission network to leap from 250MW last year to about 2,000MW by August 2021 and the majority of that new capacity will be four hour batteries.


Four hours is considered to be the sweet spot for mitigating peak demand on a daily basis as solar ramps down in the late afternoon and evening from about 4pm or 5pm to 8pm or 9pm in California, while four hours is also the sweet spot for lithium-ion batteries to provide that capacity, before the technology starts to become more expensive than other resources like CCGTs (at present). With California having faced a difficult balancing act to meet peak load during last summer’s August heatwave, this summer season will be the real test, Mark Miller says.


“That [battery] asset has a lot of flexible technology, from grid support [applications], like frequency support or spinning reserve, but primarily why it was contracted is peaking capacity, and to cover that net peak during the most critical part during the summer season,” he says.


“This year is going to be a very interesting period of time, because we’ll now have a 100MW, four-hour duration battery in the system operating moving into the peak summer season. We’re anxious to see it perform — which we’ve got a high level of confidence that it will — and SCE by that point will be very, very capable of understanding how they plan to utilise it through that peak period of the summer.”


AES believes the project and the way it won out through a competitive solicitation process planted a seed for future deployments, not least of all because SCE itself has made other contract awards for battery storage as a peaking asset since Alamitos, Miller says. Indeed, as of December 2020, SCE said it had procured and contracted for around 2,050MW of energy storage capacity. 

Alamitos: A timeline

1968:


Unit 1 at San Onofre Nuclear Generating Station (SONGS) goes into action and remains so until 1992.


JUNE 2013:


Southern California Edison (SCE) announces decision to permanently retire Units 2 and 3 at San Onofre Nuclear Generating Station. The two units were safely shut down in January 2012: unit 2 after a planned routine outage, Unit 3 due to a leaking tube in a steam generator installed in 2010.


“Looking ahead, we think that our decision to retire the units will eliminate uncertainty and facilitate orderly planning for California’s energy future,” SCE president Ron Litzinger says.


SEPTEMBER 2014:


SCE unveils the Tehachapi Energy Storage Project, part-funded by the US federal Department of Energy (DoE) at Monolith, a substation in the utility’s service area close to the Tehachapi Wind Resource Area, supporting the rapid expansion of renewables. At 8MW / 32MWh, using LG Chem batteries, it was a rare four-hour duration utility-scale battery and at the time, the largest battery energy storage system in North America.


“This installation will allow us to take a serious look at the technological capabilities of energy storage on the electric grid. It will also help us to gain a better understanding of the value and benefit of battery energy storage,” Dr Imre Gyuk, programme manager for energy storage at the DoE explains at the time.


NOVEMBER 2014:


Meeting local reliability needs as part of that “orderly planning”, Southern California Edison awards 2,221MW of contracts — around 10% of the utility’s peak load usage — following an all-source procurement for capacity requirements. SCE receives more than 1,800 final offers and selects 69 including energy efficiency, demand response and solar as well as marking the first time the utility has contracted with energy storage projects through a competitive solicitation.


A minimum of 50MW of energy storage is expected to be procured — in the end SCE contracts for 261MW, including a 20-year power purchase agreement (PPA) for AES’ 100MW / 400MWh Alamitos project.


The outcome is a “monumental decision” that “demonstrates that energy storage can be competitive with other preferred resources on both performance and value, and that it’s now an integral part of the utility planning tool kit in California,” says Janice Lin, executive director of the California Energy Storage Alliance.


DECEMBER 2015:


AES signs 1GWh supply agreement with battery manufacturer LG Chem; a deal worth around US$300m according to one analyst at the time. AES’ existing pipeline of projects is estimated by the analyst to be about 100MWh.


JULY 2017:


AES closes US$2 billion financing for the Southland Repowering Project, which involves retiring 2,075MW, 1,392MW and 474MW of gas at its Alamitos, Redondo Beach and Huntington Beach facilities respectively, to be replaced by the Alamitos battery system and 1,284MW of combined cycle gas generation.


Also that month, AES and Siemens launch energy storage technology provider and system integrator Fluence. The joint venture is initially a vendor for both AES’ Advancion energy storage which up until then had been deployed across 200MW of projects worldwide as well as Siemens’ Siestorage products. Later, Fluence launches its own range of branded systems, bringing out its sixth generation in 2020.


JUNE 2019:


Fluence breaks ground on the Alamitos project, setting an expected date for it to be operational at the beginning of January 2021, a year earlier than original plans.


“Alamitos energy storage will stand as the first of a new generation of energy storage procured as standalone alternatives to new gas plants. It represents a whole new way to think about capacity and reliability. Its size, flexibility and long duration stand as a benchmark, and showcase energy storage as a mainstream option for peaking power and grid support,” explains Fluence chief operating officer John Zahurancik.
