Battery lifespan to match generation assets

In recent weeks, discussions over the credibility of Elon Musk’s statements have been culminating. Even though the commencement of the Model 3 production and Q2 deliveries grabbed the most attention, the last few days indisputably belonged to Tesla’s Australian energy storage deal. Much to my surprise, the project has been immediately surrounded by a strong wave of skepticism, which comes primarily from Tesla’s short sellers. For example, Seeking Alpha fellow contributor Montana Skeptic wrote:

If the South Australia deal were going to change the losing trajectory of Tesla Energy, wouldn’t Tesla be announcing the great news in a press release, accompanied by tweets from Musk? Of course it would, and of course, he would.

However, as convincing as these statements and main arguments of the article may seem at first glance, I believe that they fail to put the deal in a broader context and as a result provide a distorted view of the reality.

Let me explain this further in the following paragraphs.

Is money the only benefit Tesla gets from the Australian deal?

Certainly not. As Elon Musk emphasized on several occasions, Tesla’s mission is to accelerate the world’s transition to sustainable energy. In this sense, Tesla focuses on goals greater than making money every single quarter and therefore financial details of the latest giant battery deal in South Australia should be seen at least as important as the company’s reputation, credibility and expertise.

Apart from helping to solve Australia’s power problems, Tesla’s energy storage solutions also support numerous other applications such as electricity price optimization or availability of an emergency backup in the event of a grid interruption due to unexpected environmental disasters, which was the key rationale for building the world’s current largest battery system in Southern California.

With a constantly growing share of renewables in the global energy basket, the demand for energy storage systems will only rise. More and more commercial subjects will be looking to take an advantage of peak shaving, load shiftingand demand response features of energy storage systems and therefore Tesla needs to be building its brand in this sector from now on.

Was the tender non-standard by any standard measure?

Although the majority of media reported that there were 91 bidders on the project, 14 bidders were invited to provide more detail and five considered for detailed assessment, some observers suggest that the tender was rigged and “normal bidding procedures were sidestepped“. If this were true, some investigation would likely have been already launched and a tangible evidence would have been provided. Without any material testimonies, these allegations remain just false assumptions and Twitter photos will mean nothing more than Twitter photos.

Unveiled just before the July 4th holiday, Massachusetts’ new energy storage target left a bittersweet taste with many battery companies. 

On July 1, the state’s Department of Energy Resources set a target for the state’s electric distribution companies to procure an aggregate of 200 MWh of energy storage by Jan. 1, 2020. But the State of Charge report that the DOER issued in September 2016 had said that the state could support a 600 MW energy storage target.

“The 200 MWh target is slightly under par even after accounting for potential market ramping from 2020 to 2025, as costs keep coming down and market is more mature,” said Ravi Manghani, director, energy storage at GTM Research.

And Timothy Fox, vice president and research analyst at Clearview Energy Partners, said the target set was “far more modest than broad stakeholder expectations.”

Fox also noted that the DOER target is less stringent than proposals offered by the state’s electric companies. “Unitil, Eversource and National Grid collectively recommended voluntary targets of 200 MW, 500 MWh by 2020, and 600 MW, 1,500 MWh by 2025.”

But “the key to understanding the target is the time frame,” said Judith Judson, Commissioner of DOER.

The 600 MW target recommended in the State of Charge report was for a 2025 timeframe. The recently set target has a 2020 target date to coincide with the deadlines in Massachusetts’ comprehensive energy bill signed in August 2016.

The energy storage target is “more aggressive than what was required in the law, Judson noted, but she also notes that there are several other programs aimed at bolstering energy storage, and they should all work in concert to move storage forward in Massachusetts.

“The new target sets up the state perfectly for hitting the 600 MW target by 2025,” she said.

In addition to the recent energy storage target, the DOER has implemented several measures to promote energy storage in Massachusetts since the State of Charge report was released last year,

Judson said Massachusetts was the first state in the nation to offer incentives for combining solar power installations with energy storage through its Solar Massachusetts Renewable Target (SMART) program. And the state’s ongoing solicitation for 1,600 MW of offshore wind also allows for pairing storage with wind resources.

It also shows that increasing the deployment of energy storage combined with renewable energy would help Minnesota meet its statutory goal of 80 percent carbon reduction by 2050 sooner and at a lower cost than other technologies.

The report, “Modernizing Minnesota’s Grid: An Economic Analysis of Energy Storage Opportunities,” is the result of months-long effort led by the Energy Transition Lab (ETL) at the University of Minnesota’s Institute on the Environment. Lessons learned could also be applied to other Midwest states that are in the Midcontinent Independent System Operator (MISO) footprint.

“Energy storage is a linchpin for Minnesota: It has the potential to reduce our system costs, increase electric grid resiliency, and even decrease greenhouse gas emissions in our broader coal-dependent region,” said Ellen Anderson, director of the Energy Transition Lab. “While the federal government questions the reliability of renewable energy, states like Minnesota are stepping up to show it’s possible to connect renewables and storage to reduce both costs and greenhouse gas emissions, while maintaining a reliable grid.”

Input from dozens of Minnesota energy experts laid the foundation for the analysis and final report. ETL convened more than 60 stakeholders, including representatives from utilities, energy technology companies, nonprofits and government, in two Energy Storage Strategy Workshops starting in 2016 to assess the opportunities for energy storage in Minnesota and at MISO. Participants explored whether and how energy storage could be used to help Minnesota achieve its energy policy objectives, and enable greater system efficiency, resiliency and affordability. Project collaborators Strategen Consulting and Vibrant Clean Energy conducted the use-case and system-wide modeling for the analysis, with input from MISO.

In addition to showing that storage plus solar already could be more cost effective than peaking gas plants, including environmental benefits, the analysis shows that the deployment of storage in Minnesota is projected to increase the use of low-cost renewable energy generation dispatched in MISO and to reduce the need for expensive transmission investments.

Furthermore, it shows that as standalone storage becomes more economic, it will be able to compete with and displace new gas combustion turbines installed to meet peak demand. Beyond 2022, storage was found to be more cost effective than a simple cycle gas-fired peaking plant for meeting Minnesota’s capacity needs.

Connexus, Minnesota’s largest distribution cooperative, was a participant in the workshops and is already pursuing procurement of a 20MW, 40MWh energy-storage system. It will be one of largest storage projects of its kind in the Midwest. According to Connexus, responses to its Request for Proposals have been encouraging, with prices even more competitive than anticipated.

Two of the biggest names in energy storage development have decided to join forces.

AES, a leader in megawatt-hours deployed, will launch a new company along with global energy systems provider Siemens. The jointly owned venture, dubbed Fluence, will scale up commercial and grid-scale storage deliveries worldwide.

The unprecedented move marks a pre-emptive consolidation of power in a young industry — and a new competitor for emerging market leader Tesla. 

AES started deploying large utility-scale storage a decade ago, making it a seasoned veteran in the new and emerging advanced energy storage world.

The major independent power producer deployed its own projects in PJM’s frequency regulation market, and gradually transitioned to selling its Advancion system to third parties. The company recently completed the largest lithium-ion battery to be deployed date for San Diego Gas & Electric as part of the Aliso Canyon gas leak response.

It could have kept going with the same game plan. But early leaders of emerging markets don’t always retain that lead. With Fluence, AES hopes to solidify its position amid an increasingly bustling competitive landscape.

“We have to massify this product to continue to bring down costs,” said AES CEO Andrés Gluski, in an interview. “On long-duration systems, we think we’re the most competitive in the market, but we’ll be even more competitive if we’re even larger.”

For more than a century, Siemens has built the heavy-duty equipment that drives the grid, like generators and balance-of-plant devices. In the storage space, it has focused on commercial and industrial development for the last five years with the Siestorage product, and will bring that expertise to the joint venture.

Perhaps more consequential, though, is the company’s global footprint, which includes a sales presence in 160 countries with deep ties to utility, industrial and commercial customers.

“If you look at our energy business, we’re very well connected with all the leading utility players in the world,” said Dan Wishnick, sales and business development manager at Siemens Energy. “It’s a rare customer we haven’t touched in some shape or fashion.”

California’s SGIP program is the largest state-sponsored behind-the-meter storage incentive in the country, and the application process is exceedingly complicated.

The program recently re-opened after a nearly two year hiatus so that it could be reformulated in order to make the process more equitable. SGIP attracted controversy in previous years with reports that some companies were able to wind a lion’s share of the awards.

In revamping the process, the state also put a greater emphasis on energy storage and de-emphasized other renewable technologies, which are covered under other incentives. The program now has $448 million earmarked for storage, 79% of the total, spread over five rounds of allocations.

That funding could beget as much as 800 MW (1600 MWh) of storage, depending on how incentives are allocated, according to an analysis of the program from consultancy Strategen. That likely means hundreds of permit requests for installation and interconnection of small storage systems — a burden some local governments could find difficult.

AB 546 seeks to help, calling for a storage permitting handbook for government agencies. A similar guide already exists for applicants to the storage program, and the government handbook would be positioned as a model for other states. 

“The purpose here is to give cities and counties helpful tools,” Alex Morris, director of policy and regulatory affairs for the California Energy Storage Association, told Microgrid Knowledge. “The vast majority of projects are small behind-the-meter projects that have to connect with the utility and go through the permitting process.”

A supply deal has been signed, for components made by Ideal Power to be integrated into NEXTracker’s solar-plus-storage offerings, including power conversion system and solar PV inverter.

NEXTracker, a leader in single-axis tracking systems for ground-mounted PV systems, launched NX Fusion and NX Fusion Plus, the two products that constitute its pre-wired, pre-assembled solar-plus-storage solutions, earlier this year in multiple regions.

NX Fusion and NX Fusion Plus allow users to create their own “renewable power plant”, the company claims, with the inclusion of battery energy storage from flow machine maker Avalon Battery, which won a competitive selection process to become NEXTracker’s exclusive battery supplier.

Now, NEXTracker and Ideal Power have announced the formalisation of their supply deal, signing a master purchase agreement, which was revealed o Monday morning. Ideal Power’s ‘SunDial’, a 30kW multi-port PV string inverter and ‘Stabiliti’, a 30kW power conversion system will be bundled with NX Fusion Plus. One or the other device, or both, will be fitted to systems as required by customers.

Ideal Power touted the advantages of SunDial: it is field-upgradable, with plug and play bidirectional current (DC) power port kit, and its DC-coupled configuration makes it simpler to work with than AC systems, the company claims.

“NEXTracker’s solar-plus-storage product helps safeguard against the reduction or elimination of net metering incentives for new solar installations happening across North America, while providing a higher return on investment than solar alone.

“Customers should also be able to access the 30% federal investment tax credit available for storage installed with new solar. We are pleased to partner with NEXTracker to deliver this superior product,” Ideal Power CEO Dan Brdar said.

Meanwhile Ideal Power chairman Lon Bell said the agreement with NEXTracker allowed Ideal to focus on energy storage markets which he said the company believed would “benefit from our proprietary multi-port and microgrid-capable products”.
