Energy Storage Leaders Stumbled, Then Survived

— March 20, 2015

At a time when the major electric industry players were either unwilling or not nimble enough to develop energy storage systems integration expertise, four growing energy storage players with four distinct technologies took a risk to develop this expertise. Over the last few years, each of these companies failed financially and was subsequently acquired, in some cases more than once. In nearly every case, private equity firms stepped in, seeing an opportunity to invest in a maturing technology company with specialized expertise in the market.

Citing Tesla founder Elon Musk’s determination to build a massive Gigafactory to manufacture batteries for his vehicles, E Source Senior Fellow Jay Stein has argued that company failures like these indicate the shortcomings of the overall market. This is a logical fallacy.

Detours Behind

The chart above is derived from Navigant Research’s Energy Storage Tracker 1Q 15, a global database of energy storage installations that includes 808 projects. This specific graph charts the top 10 systems integrators of energy storage in terms of number of systems deployed globally. Four of the 10 market leaders for systems integration have gone bankrupt and been acquired in the past several years. NEC Energy Solutions, formerly A123 Energy Solutions, was acquired following a bankruptcy filing, and the grid business was subsequently spun off and sold to NEC Corporation for approximately $100 million in 2014. Beacon Power was acquired by a private equity firm following a bankruptcy filing in 2012, and Xtreme Power (now Younicos Inc.) was acquired by Younicos AG in 2014, also after filing for bankruptcy.

All three firms were focused on a core grid storage technology (lithium ion batteries, flywheels, and advanced lead-acid batteries, respectively), but all spent a great deal of resources in the earlier days of the market learning how to integrate complete systems. Ultimately, all three firms developed this expertise, and NEC Energy Solutions and Younicos repositioned themselves as systems integration companies, offering software, controls, and integration expertise as opposed to pure-play battery suppliers. Beacon Power is a market leader in flywheels and flywheel systems integration and has developed a modular flywheel product with built-in power electronics for simpler integration and installation.

Managers, Not Markets

Finally, Coda Energy repositioned itself as an energy storage integration firm in 2013 after filing for bankruptcy. The company rebranded and shifted its product offering to target stationary energy storage using a battery management system, battery thermal management, and a sophisticated power source controller.

Together, these four companies account for 21% of the global market share for the top 10 systems integrators (although part of this market share is attributed to Younicos AG). These companies and others like them are challenging incumbents such as ABB and S&C Electric, demonstrating that their earlier stumbles arose out of flawed management and/or strategy, not failed markets or futile technologies.

Equating a management failure with a market failure ignores the value of the technology. Whether the Gigafactory will be Musk’s Waterloo or Austerlitz has less to do with the technology and much more to do with Tesla’s strategy and execution—and Musk has proven he can accomplish both in the automotive and the financial services worlds.


E-Motorcycles and E-Scooters Primed for Acceleration

— March 17, 2015

Innovative product offerings, large new market entrants, and decreasing battery prices are all contributing to an increasingly positive outlook for the electric power two-wheel vehicle industry, which includes electric scooters (e-scooters) and electric motorcycles (e-motorcycles).

An influx of new product offerings and services in these markets is expanding the product options for consumers, offering legitimate alternatives to car ownership, and appealing to new, untapped customer bases. These products and services include fold-up e-scooters, hydrogen fuel cell scooters, e-scooter sharing programs (Scoot Networks), e-scooter battery swapping networks (Gogoro), and ultra-lightweight e-motorcycles.

Warming Up

In the e-motorcycle industry, several large manufacturers traditionally focused on gasoline-powered motorcycles are entering the market and providing new capabilities. These large companies bring brand recognition, extensive dealer networks, industry credibility, and large marketing and R&D budgets. It’s difficult to convince consumers to buy unknown brands in a new market, especially at higher price points compared to internal combustion engine (ICE) motorcycles.

With Polaris Industries acquiring Brammo in early 2015, Yamaha announcing its intention to enter the market in 2016, and Harley-Davidson expected to release its LiveWire product around the 2018 timeframe, the e-motorcycle industry is poised to undergo significant growth and significantly increase consumer awareness and recognition over the coming years. Lithium ion (Li-ion) battery units that would have cost more than $1,000 per kilowatt-hour (kWh) just a few years ago can now be had for about one-third of the price, and these costs are expected to continue to decline over the coming years.

According to Navigant Research’s recently published report, Electric Motorcycles and Scooters, worldwide sales of e-motorcycles and e-scooters are expected to grow from 5.2 million units in 2015 to just under 6 million units by 2024. Due to the new and expected market entries of Polaris Industries, Yamaha, and Harley-Davidson into the North American and European markets, high-powered e-motorcycles (more than 30 kW/40 hp peak) are expected to achieve by far the largest growth of any segment in this market, growing at a compound annual rate of 35.2% between 2015 and 2024.

Islands Sail into Energy Storage

— March 3, 2015

Saddled with the highest electricity rates in the world (and threatened by climate change more than almost any other communities), many islands and isolated grids have opted to integrate wind and solar to replace expensive, imported diesel fuel. One challenge for these systems is that they do not have the benefit of calling upon neighboring systems to balance their wind and solar against load–leading to instability and insecurity of supply.

As a result, many remote grids are adjusting their technical requirements for connecting intermittent resources like wind or solar to the grid, requiring that these resources be firmed. In late 2013, for instance, Puerto Rico adjusted its technical requirements for connecting wind and solar assets to the Puerto Rican grid. This isn’t a direct requirement for energy storage specifically, but is a good fit for storage.

The Flywheel Option

Other island markets are betting on storage more directly. Aruba has committed to an aggressive plan to become 100% renewable by 2020 and has signed agreements with BYD and Temporal Power, as well as a power purchase agreement with Hydrostor in order to achieve its energy goals.

The typical applications in these markets are wind, solar, and diesel hybrids. In previous years, the most common technology for remote, isolated grid storage was advanced batteries. This was partly a function of availability and technology fit. Very few other storage technologies are modular–underground compressed air and traditional pumped storage require specific geologies–and few vendors were targeting the space. Moreover, the working assumption in terms of technology fit has been that a longer-duration storage system is more valuable than a short-duration storage system. Several flywheel vendors are disproving this assumption, however.

ABB’s Powercorp, for example, uses flywheel technology in remote microgrids, such as the BHP Billiton nickel mine in Western Australia and the Coral Bay community in Northwestern Australia. These are remote diesel-led systems.

Way Up North

Beacon Power has commissioned a demonstration project in St. Paul, Alaska, combining an existing plant, which includes a 225-kW wind turbine and 300 kW of diesel generators, with a 160-kW flywheel system. In this scenario, the flywheel system will enable the host utility to further improve wind utilization and deliver fuel savings of up to 30% over existing (pre-flywheel) consumption levels.

While it is still the case that some amount of long-duration storage is necessary in order to achieve very high renewables penetration on an isolated grid, flywheels are demonstrating that significant diesel savings can be achieved with as little as 30 minutes or less of storage.


Utility-Scale Energy Storage: The Next Killer App

— February 10, 2015

In recent years in the power sector, companies like C3 Energy and Space-Time Insight have been introducing groundbreaking applications that can provide powerful data and insights across the utility value chain, from the customer to the independent system operator (ISO). Looking back over the Navigant Research utility transmission and distribution technology forecasts in our syndicated reports—and our 10-year forecasts for those technologies—it’s clear that utility-scale energy storage is among the technologies undergoing the most dramatic transformations, thanks to these applications.

Since 2009, the California Energy Commission (CEC) and the U.S. Department of Energy (DOE) have invested millions of dollars in utility-scale storage through both smart grid demonstration project funds and Advanced Research Projects Agency – Energy (ARPA-E) R&D grants.

Next-Generation Investment

In December, Eos Energy Storage announced that it had won a $2 million award from the CEC to deploy and demonstrate a 1 MW grid-scale battery system at Pacific Gas and Electric’s (PG&E’s) Smart Grid Lab in San Ramon, California. The project, called Aurora, was the only advanced battery storage system recipient of grant funding.

According to Eos, its Aurora battery system “can be manufactured at a fraction of the cost of existing energy storage solutions.” The Edison, New Jersey-based company is joining with PG&E, the Electric Power Research Institute (EPRI), Lawrence Berkeley National Laboratory (LBNL), distributed energy storage technology pioneer Stem, and ETM Electromatic to carry out the project.

“This type of project deployment can meet the requirements of California’s utilities and industrial users at a price that will compete with gas peaking plants, providing both peak generation and infrastructure benefits,” said Philippe Bouchard, Eos vice president of Business Development, in a statement.

Strategy for Scale

Eos’ Aurora direct current (DC) battery, power electronics from ETM, and Stem’s real-time data analytics are being implemented at PG&E’s Smart Grid Lab in San Ramon.  EPRI is managing interconnection and systems integration requirements. LBNL will employ real-time grid simulation to assess “system benefits under dynamic load and renewable integration use cases.”

The Eos Aurora 1000/4000 battery system delivers 1 MW of electrical power for 4 hours, which is more than enough to mitigate peak power demands, thus avoiding costly investments in transmission and distribution upgrades. It also offers fast-response surge capabilities that can manage the intermittency of solar, wind, and other renewable energy grid assets.

Looking further down the road, so to speak, it’s clear that energy storage will advance thanks to major investment from car makers such as Tesla, which is placing its bets with the new Gigafactory in Nevada. Large volumes of mass-produced batteries will be essential to Tesla and other electric vehicle manufacturers. And this mass production strategy for battery technology also brings increased scale that may reduce deployment costs. With clever engineering, this strategy will help expand residential and utility deployments, as well.
