Homer Electrical Affiliation (HEA) lately launched a big battery vitality storage system (BESS) at its Soldotna Era and Substation Facility in Soldotna, Alaska, utilizing a battery system offered by Tesla.
It consists of 37 Tesla Megapack containers (52,000 kilos / 23,587 kg every), and in line with HEA, it has an influence output of as much as 46.5 MW.
The battery capability is estimated at 93 MWh, which implies that as soon as totally charged, it theoretically would be capable of work at full energy for 2 hours (or proportionally longer at decrease energy). After all, we all know that at a low state of cost, the facility output normally occurs to be restricted.
In 2021, Tesla launched its first Supercharging station in Alaska (additionally in Soldotna).
This new BESS is predicted to considerably strengthen Alaska’s Kenai Peninsula grid and scale back the group’s reliance on fossil fuels to energy the generators.
In response to Tesla, the realm has traditionally relied on fuel generators to distribute energy to the group as much as 4 months out of the yr.
The temperatures is perhaps as little as -30°F (-34.4°C), however the Tesla Megapacks have been designed to supply grid stability “even in freezing temperatures.”
“The brand new battery vitality storage system will probably be used to steadiness system calls for with its larger capacity to ship or obtain vitality (as much as 46.5 MW per hour). This additionally permits base loaded thermal models to be run extra effectively whereas permitting for elevated integration of utility scale non-dispatchable (vitality era that may’t be scheduled) renewable vitality sources (i.e., wind & photo voltaic).”
HEA shared fascinating movies final yr in regards to the mission, displaying preparations and set up of the Megapacks. In response to the corporate, its crews spent the higher a part of 2021 getting ready for supply of the batteries:
In 2021, Tesla has deployed (totally accomplished tasks) nearly 4 GWh of vitality storage methods (Powerwall, Powerpack and Megapacks), which is 32% greater than in 2020.
The corporate plans to construct a brand new 40 GWh Megapack manufacturing unit in California, and swap its vitality storage methods to iron-based batteries, aka Lithium Iron Phosphate (LFP).
