Tesla Powerpacks Provide Energy Storage For North Carolina Island

Tesla Motors has made green-friendly power a reality on yet another island. The gorgeous Ocracoke Island in North Carolina’s Outer Banks is now home to 10 Tesla Powerpacks. The island will not have to completely depend on its old method of power – a 3MW diesel generator – as a new microgrid will work in tandem with the diesel system, and solar arrays will provide additional backup power.

As we understand it, these are original 100 kWh Powerpacks, not the recently update Powerpack 2.0 offering (full details here) that are rated at 200 kWh – with Gigafactory built inverters that begin shipping in September.

A microgrid, as defined by the U.S. DOE is:

A group of interconnected loads and distributed energy resources within clearly defined electrical boundaries that acts as a single controllable entity with respect to the grid and that connects and disconnects from such grid to enable it to operate in both grid-connected or island mode.

The new system is being managed by Tideland Electric Membership Corporation (TEMC), supplier of the island’s power. The Ocracoke Island power situation is a pilot program between the North Carolina Electric Membership Corporation (NCEMC) and Tideland. Heidi Smith, a spokeswoman from TEMC shared:

“This is a learning laboratory for Tideland. We’re exploring the potential for a microgrid. The Tesla batteries could potentially help us get over that start-up load. It will be interesting to learn what benefits can be derived from the various microgrid components over time.”

NCEMC’s project manager, Bob Beadle was on the island throughout the installation process. He is excited about the future and proud of the new development. Beadle said:

“We’re setting up here for the electricity of the future.”

Unlike other recent similar projects, like the one in Ta’u (American Samoa), the system on Ocracoke can’t completely sustain the island on its own. However, if the project is a success, expansion is a possibility. Also, Tesla’s second-generation Powerpack 2 – with double the capacity – could replace the first-gen units in the future.

Another reason that Ocracoke, and any similar coastal areas, is a worthy test site for Tesla’s product, is the severe weather patterns. The batteries have internal temperature controls and are constructed to function in any weather condition. Coastal and island environments will determine if the Tesla Powerpacks can live up to expectations.

      Even after more than a decade, the Utsira project is not plain sailing

      ““One problem is making enough hydrogen,” Nakken comments. “The operational flexibility of the electrolyser is such that we cannot utilise all surplus wind power. At the same time, the efficiency of the hydrogen engine is low so we consume a lot of hydrogen.

      “This, together with the fact that the consumers are now using more energy than in the beginning, means we could run out of hydrogen when longer windless periods occur. If this happens, we’ll connect the customers back onto the ordinary grid.”

      The fuel cell has caused the most problems. “For various reasons we have not been able to fully integrate the fuel cell as part of the system. However, the fuel cell is not critical to operating the plant. The main reason for including a fuel cell was to gain experience with what we thought to be the future solution,” Nakken says.

      “High cost and low durability still makes this technology prohibitive. The hydrogen-fuelled generator is a good near-term alternative. The hydrogen engine at Utsira is converted from a natural gas unit and has the capacity to cover the total customer load.”

        Wow.

        Electrons from wind -> electorlizer -> H2 -> ICE is insanely low efficiency.

        A battery round trip would likely cheaper these days.

      The Ramea project includes using the existing diesel and info hasn’t been updated in years
      The Hawaii tidal project looks interesting.
      I got this from the link – “The electrolyser will be packaged in a standard 20’ and 10’ ISO container with hydrogen generation capacity up to 220kg/24hours”
      It’s not clear what that means – does it take 24 hrs to produce 220kg of hydrogen or that 220 kg of hydrogen will provide 24 hrs of electricity generation?

      1. floydboy says:

        Since they’re saying “generation capacity”, I’m assuming it means how much they can create in a 24 hour period.

    Too late for Tangiers island in Virginia it’s already underwater.

      90% of land loss in Louisiana has been caused by the oil companies due to canal dredging. Land that has been lost is equivalent to the size of the state of Delaware.

    i think these solar/wind + power back microgrid are a good start, but add the new Tesla solar roof + Powerwall, and this solution may be all that’s needed. Especially since the homes or buildings can be generating and storying their own energy.

    There needs to be a nationwide effort where builders are required to build X percentage of energy sustained(solar/energy storage) homes. Which would make the solution even more affordable.

    1. Mister G says:

      Are you kidding me that’s more government regulations, Trump is not gonna go there lol…elections have consequences and we are in for a nightmare.

    2. Sy Gung Ho says:

      This could be done state by state. All new homes should be built with solar collectors by law.

  3. Bob Nan says:

    Very good move. Of late, both Solar & Wind energy are cheaper than Coal & Gas and much cheaper compared to Oil.

    Makes good sense. Even Saudi Arabia is moving from Oil to Renewable energy.

    Can someone please translate these to KWh or Wh. This webpage quotes battery price in Ah.

    Solar power is liberal witchcraft sorcery. Typical left-wing media publishing pro-solar power stories.
