iDemand Energy Storage Completes First Out-of-State Project


Drenched with snow in the winter and sun in the summer, a 3,000-square-foot home on 20 acres in Southeast Utah that is both a vacation respite and ecologically balanced horse ranch was iDemand Energy Storage’s (iDES3) first out-of-state project.

In late January, iDemand’s COO Ray Trejo traveled from the company’s San Diego offices to Fruitland, Utah, to oversee installation of a 36 kilowatt hour sustainable energy storage battery unit, the largest model of the company’s Echo indoor series. Tied to the Echo are 24 kilowatts of OutBack inverters.

The uninterrupted-energy-supply (UES) battery system was connected to 13 KWs of ground-mounted solar arrays installed by Salt Lake City-based GoSolar Group.

While the project is relatively small from a financial perspective for iDES3, the perimeters under which the installation took place and the location represent a company first.

“Not only is this our first installation outside of California, it also proves that our product will work in inclement weather,” Trejo said. “Temperatures range between a negative 15 and 90-plus degrees in the summer and it was negative 5 when I was there.”

Aside from the solar arrays and energy storage battery unit, there is a 15 KW generator on the property. Together they create grid independence by powering the house, a separate garage and two pumps that draw water from a creek to hydrate an agricultural crop via a sprinkler system.

iDemand Energy Storage Inc. (iDES3) has begun engineering and design work on a $4.1 million solar-plus-battery storage project that will lower dependency on the investor-owned utility and reduce the carbon footprint for five buildings belonging to a San Diego County-based biotech company.

The contract to manufacture uninterrupted-energy-supply batteries capable of storing and discharging up to 1.078 megawatts of solar energy was awarded to iDES3 in early January by SunFusion Solar Inc. Both are San Diego companies.

“One of the challenges of this project will be to customize solar awnings that will hang off the sides of the buildings,” said Ray Trejo, co-founder and senior vice president of six-month-old iDES3. “They will need to be specially engineered to ensure that they’re not too heavy. There will also be solar arrays atop carports and rooftops.”

Work, including installation of the battery units and solar arrays, is expected to be completed in mid-October. The name of the biotech concern is being withheld pending iDES3’s patent applications for the solar storage technology, Trejo added.

“This is the first of potentially several projects for the biotech company, which in addition to its buildings in San Diego County, also has facilities in Baja, Mexico,” said Sandy Ellard, president of SunFusion.

The client’s objective is to shave peak-load electricity demand during the middle of the day by using energy discharged from the battery units that was stored overnight. During peak-demand periods, utility companies charge higher rates than in off-peak times, Trejo said.

Rates may run as high as $20 per kilowatt between noon and 6 p.m. and $15 per KW from 6 p.m. to 10 p.m. “It all depends on the utility jurisdiction,” he said.

However, utility companies will essentially “double-dip” by adding what’s called a non-coincidental charge on top of the peak rate any time they detect a user’s maximum rate. “But our battery system looks for a rise in demand and it automatically discharges stored power to level off the demand load,” he explained.

The biotech contract, which calls for 900 kilowatt hours for the five buildings’ load is the largest to date for the startup battery manufacturer.

SunFusion Solar has averaged sales of $4 million annually since it was founded in 2010.

iDemand Newsletter November - December

San Diego – (November - December 2016) Since iDemand Energy Storage (iDES3), a manufacturer of sustainable-energy battery units cofounded by Walter Ellard, Raymond Trejo and Pierre E. Leroy, opened in mid-August, it has garnered tens of millions of dollars in residential and industrial contracts, and has more than tripled its staff, including the addition of three engineers.

Ellard and Trejo, a mechanical engineer, both have extensive experience in the renewable energy sector, and hold C-10 electrical contractors’ licenses.

Leroy has held a number of senior executive positions, including CFO of a Fortune 500 company and president of a multibillion dollar worldwide division. Most recently he served as CEO and executivechairman of a startup company. In 2015 he launched a consulting firm aimed primarily at helping entrepreneurial ventures take advantage of the digital revolution.

iDES3 is finalizing terms on a contract valued at $10 million to make systems with 2 megawatt-hour battery units that will store energy from 1.72-MW solar arrays for a medical company that has three separate buildings in Southern California and two in Baja totaling about 2 million square feet. Work, including the solar installations by SunFusion Solar Electric Inc., is expected to begin in December.

iDES3 is also in talks with agovernment contractor to manufacture a 2.7-MW-hour energy   storage system for two buildings and a parking structure totaling approximately 2 million square feet in San Diego. In combination with solar arrays, the battery units could save that company roughly $81 million in utility costs over 30 years. The value of that contract is $22 million.


Walter Ellard

Ellard credits the success of iDES3 to its technical expertise as well as superior battery units comprised of lithium iron phosphate in large formed prismatic cells, for “maximum performance.” 


Raymond Trejo

Said Trejo, “Ours are the only whole-house, whole-building systems on the market today. That means they’ll pick up all your heavy-hitting loads, such as air-conditioning, pool pumps and electric-vehicle chargers while providing ample output for other appliances and needs. Furthermore, we provide a bumper-to-bumper warranty for the entire system for up to 25 years. Nobody else in our business does that.”


Pierre E. Leroy

Leroy adds, “We have today what Tesla has been unable to provide its customers – a system allowing them to get off the grid with software creating unique battery management, all of which is internet capable. Thus, it allows us to continually monitor and know if our product is operating efficiently.

Meanwhile, a recently completed project at a 4,600-square-foot laboratory in El Cajon for Advanced Dental Arts, as cited in an Oct. 27thpublication of the San Diego Business Journal, couples a 22-KW-hour battery unit with a solar array by SunFusion Solar. Vicki Jones, the laboratory’s owner, said that she was accustomed to monthly electric bills ranging from $1,200 to $1,700, and while she’d yet to receive her first bill following installation of the solar-plus-energy storage system, she expected it to reflect freedom from the grid.

To accommodate projected growth that will bring iDES3’s employee roster to 200 by April of the coming year, Ellard is in negotiations to lease a 33,000-square-foot warehouse in Temecula.

Specifications of the iDES3 system:

  • Mounting: Wall or floor, indoor/outdoor
