Selecting the Right Inverter: Maximizing the Value of C&I Energy Storage Systems
Each year power outages cost commercial and industrial businesses tens of billions of dollars in lost productivity. Of the over 3,500 power outages nationwide last year — two thirds of which lasted under 5 minutes — deploying energy storage systems capable of seamless transition to backup power could save American businesses tens of billions of dollars each year.
But in order to add the value of back-up power with energy storage systems used to defray demand charges for commercial and industrial businesses, the right inverter needs to be selected.
In this webinar, Dynapower’s Chip Palombini and Apurva Somani will address:
Considerations when selecting an inverter for commercial and industrial ESS
The benefits of seamless transition compared to through stop transition when integrating back up power in an ESS
Ability to scale ESS system as business needs grow
Cost for integrating and deploying back up power — it’s nominal.
DYNAPOWER AND SAMSUNG SDI LAUNCH INTEGRATED STORAGE SOLUTION
FOR THE BEHIND-THE-METER ENERGY STORAGE MARKET
South Burlington, Vermont – Dynapower Company and Samsung SDI announce the introduction of an integrated behind-the-meter energy storage system built on their respective proven technologies. The initial release of the system will be a 250kW/550 kWh offering, with a 100 kW two-hour system to follow
The integrated energy storage offering provides energy storage system vendors, project developers, and utilities with a fully engineered solution that reduces costs for commercial and industrial end users in the deployment of energy storage. This line of systems will incorporate Dynapower’s recently released Generation 2 MPS product line of behind-the-meter energy storage inverters and Samsung SDI’s recently released E2 battery solution.
The two companies share a wealth of field proven integration experience of their technologies across a wide range of ESS projects, sizes and applications including the Electrical Training Institue Net Zero Plus building microgrid and Duke Energy Notrees 36MW/14MWh ESS repower.
“We have worked alongside Samsung SDI for a number of years and are excited to take that collaborative effort to the next level with the introduction of an integrated energy storage solution,” said Adam M. Knudsen, President of Dynapower. “As the energy storage industry has rapidly evolved we have seen a clear demand from the market for engineered solutions that are flexible and proven. This is a solution customers can rely upon.”
“Together, Dynapower and Samsung SDI are well positioned to help expand market opportunities for our behind-the-meter storage customers by providing fully integrated engineering solutions,” said Fabrice Hudry Vice President Energy Storage Solutions at Samsung SDI “Samsung SDI is the world leader in Li-ion battery technology, and specifically for stationary energy storage application, and it is only fitting that we integrate our batteries with Dynapower’s leading inverter technology.”
Dynapower and Samsung SDI are launching their integrated behind-the-meter ESS offering with an immediate first deployment at the University of Minnesota, and are already working with several behind-the-meter ESS developers to deploy their unique integrated solution across the nation throughout 2017.
When Green Mountain Power became the first utility in New England to use solar energy stored in batteries to “shave” peak power demand from the grid — saving $200,000 in an hour — it was South Burlington’s Dynapower that made it possible.

The electricity from batteries is direct current, or DC; the electricity from the grid is alternative current, or AC, explained Chip Palombini, Dynapower’s sales manager for the energy storage group. To put energy from its solar-charged batteries on Stafford Hill in Rutland into the grid on Aug. 12 to reduce demand for expensive peak power, GMP needed Dynapower’s “inverter” to make the connection from DC to AC.
“You need to put something between the wall outlet and the batteries,” Palombini said.
Dynapower has carved out a niche as a leading global supplier of the electronics to make this conversion from DC to AC, which came delivered in four parallel systems the size of shipping containers in the case of Green Mountain Power. Each can power 100 homes, Palombini said. Grid power storage is seen in power generation circles as the next big thing. As a result, a remarkable array of companies comes to Vermont to meet with Dynapower executives.
“You’ll see everyone from GE to Samsung, Panasonic and IBM, all come through the doors looking for our expertise,” said Richard Morin, a marketing specialist at Dynapower. “They traipse to Vermont for this little company with world renowned expertise.”
President Adam Knudsen said the best part is that Dynapower’s expertise is here to stay.
“If you look at the professional talent that … we’ve home-grown through our support of the University of Vermont and the technical colleges, it’s a great story,” Knudsen said. “Thirty-five percent of our engineering department graduated from the University of Vermont.”
The remaining percentage of Dynapower’s engineers who come from elsewhere can’t believe their luck, according to Knudsen.
“Some of our most senior power electronics people are global recruitments, but once they come in they don’t ever want to leave,” Knudsen said.

Taking on GE
Dynapower has about 200 employees in its 150,000-square-foot plant on Hinesburg Road with a wind turbine out front; a “bunch of mad Vermonters,” says Morin, who can not only engineer “these crazy things,” but also manufacture them in the back of the building.
Dynapower’s vertical integration — design and build — gives it an important advantage over the GEs of the world, according to Palombini.
“GE is a very large machine and they can do a lot of great stuff, but there’s a cost,” Palombini said. “With GE, customization is difficult. That’s what we do, custom installation.”
Customization like the system Dynapower built for the CuisinArt Resort and Spa on Anguilla in the Caribbean. Yes, the same Cuisinart that’s probably in your kitchen. The resort was burning an “astronomical” amount of expensive and smelly diesel fuel to desalinate salt water for drinking water, Palombini said.
When resort management explored the possibility of switching to solar power, the local utility wouldn’t let them connect solar to the grid. Dynapower came up with a solution.
“We delivered 20-foot shipping containers with the batteries and inverter in there,” Palombini said. “They built a solar array with one of our construction partners.”
Now, the CuisinArt resort can make up to 300,000 gallons a day of drinking water with self-contained solar power, independent of the grid. The job would have been easier with a grid connection like Green Mountain Power has, but the resort owner wanted to get the project done, and wrote a check for $600,000 to make it happen, according to Palombini.
“The great thing is it’s not just to make the golf course green,” Knudsen said. “It provides drinking water for the island. It’s a neat story about using technology to solve a real problem of grid dependency.”
From the Rust Belt to the Green Mountains
Dynapower began in Detroit in 1963, servicing the automotive industry with the electronics for metal finishing equipment such as the chrome-plating machinery for bumpers. In the 1980s, the founder’s son, Peter Pollock, came to the University of Vermont to study in the engineering department, met a girl and fell in love. Once he took over the business, Pollock decided to move the entire operation to Vermont.
“Peter’s father said, ‘You’re going to pick up a profitable Rust Belt business that serves the automotive industry and move it to Vermont? Are you crazy?'” Knudsen said.
Knudsen said if Dynapower had remained solely in its legacy business of chrome-plating bumpers, Pollock would have been crazy. Instead, the company branched into three additional areas: an energy storage group; a mining group; and a military group.
The mining group makes the equipment that separates metal from ore, using electricity.
“It’s a very similar process to chrome plating,” Palombini said. “You take the ore, pour liquid over it to create a sludge, pass a bunch of electricity through it, and now, instead of getting chrome out of solution onto a wheel, you’re getting copper particles out of a mud slurry solution onto some starter plates. All the copper particles are now separated from the dirt and rock.”
The military group makes frequency converters for missile defense systems, solving another diesel fuel-related problem.
Previously, defense systems ran off diesel generators because in the event of an attack, the electric grid is likely to be compromised, Palombini said. In forward operating areas, the cost of a delivered gallon of diesel fuel is hundreds of dollars, making the missile defense systems more expensive even than desalinating water on Anguilla.
“What our system does is enable them to connect to the grid and also to generators,” Palombini said. “If the grid goes down they can seamlessly transition to generators.”
Dynapower doesn’t release revenue figures, but Knudsen, 46, said annual revenue is in the tens of millions of dollars, and he plans to double that number by the end of 2018, pushing the company close to $100 million. Knudsen expects that growth to come from all of the areas the company works in, not just energy storage.
“It’s neat to have a role in building the power electronics that help the world optimize the use of energy, including renewable energy,” Knudsen said. “That’s just cool.”

According to GTM Research, last year less than one-tenth of one percent of solar PV installations included battery storage. These stats may suggest that the market isn’t ready for storage yet, but the reality could not be more different.
Early visionaries and advocates for the solar-plus-storage combination have generated a high level of industry attention and activity. The result is that users looking to augment their PV systems for better performance and value are signing on as technologies improve and costs fall.
One reason for this heightened interest is the rapidly declining costs of not only batteries, but of the entire solar-plus-storage system. Balance of system (BOS) components are relatively mature and suppliers are leveraging advanced materials and efficiencies in production and supply chains to keep costs down. Energy storage inverters, including solar plus storage inverters, from Dynapower, for example, are third-generation technologies that, like many high-tech products, offer increasingly superior capabilities and performance at very competitive prices.
A closer look reveals that costs for storage-plus-solar systems are also driven by the applications they’re used for. In low C-rate (high-energy, longer-duration) applications, batteries dominate the cost, increasing total project cost. On the other hand, in high C-rate applications, such as frequency regulation, peak shaving and other services, the cost for batteries is relatively small in proportion to BOS, resulting in a lower cost system.
The high and low C-rate cost breakdown is illustrated here:
Comparison of solar plus storage project costs at 2C and 0.5C for microgrid and grid tied applications.
The variable in this equation is the energy storage integration/EMS software. Pricing for this system element varies based on the complexity of the job – and is relatively independent from project size.
The solar plus storage market is growing – but what’s driving it?
GTM Research reported that solar-plus-storage deployments totaled 4 MW (DC) in 2014, but are expected to grow more than six-fold to 22 MW in 2015. By 2020, solar-plus-storage installations are projected to reach an astonishing 769 MW – nearly 200 times last year’s total. California is expected to be the biggest solar-plus-storage market, with 422 MW installed in 2020 alone.
Some of this expansion will be driven (as it often is) by declining costs, but there are other factors. Changes to net metering rate structures, for example, can tilt the market toward storage deployment for self-consumption of PV. For example, Hawaii, which has the highest percentage of PV on the grid in the country, recently overhauled its net metering policy to encourage self-consumption. This will, without a doubt, drive energy storage deployment.
Looking ahead, PV users will likely be able to offer a stack of services to the grid, such as frequency response, voltage support, and distribution upgrade deferral. A recent report from the Rocky Mountain Institute makes the case that the revenue associated with these additional services could further improve the economics of PV systems paired with smart controls and batteries.
Other factors helping to boost demand and lower costs are the growing emphasis on grid resiliency for energy security and independence, and the proven value of storage in smoothing intermittent renewable resources like PV (and wind).
Many observers have said that energy storage is where PV was six or seven years ago, and believe that the factors that brought PV to mass affordability will have a similar effect on storage. What do you think is the reason for market growth and lower costs?
