Energy Storage: Charging Ahead in 2018
GTM Research and the Energy Storage Association recently released a new report on the energy storage market. Due to the rapidly declining price of energy storage (predominately batteries), the report states that nearly 300 megawatts of energy storage is expected to be deployed in 2017 – a 28% increase over 2016. Large, utility-scale battery deployments are leading market deployments. According to Bloomberg New Energy Finance, lithium-ion battery prices have declined over 70% since 2010.
While the industry growth rate is shockingly good news, the real story is where energy storage is beginning to take hold. States like Indiana, Kentucky, Virginia, North Carolina, Georgia, Louisiana and Florida are evaluating storage options in integrated resource plans, pilot programs, and through energy storage procurement. Some examples are listed below.
- Duke Florida plans to add 50 MW of battery storage.
Kentucky Power’s IRP has plans for adding 10 MW of battery storage by 2025.
- Duke Energy in North Carolina will install a 9 MW battery system in transmission-constrained Asheville.
- West Virginia’s Laurel Mountain wind farm has a co-located 32 MW / 8 MWh lithium-ion battery system.
- Duke Energy’s Notrees Windpower Project in western Texas is upgrading from lead-acid batteries to a 36 MW lithium-ion system.
- Southern Company is testing a 1 MW / 2 MWh lithium-ion battery system in Cedartown, Georgia.
- Southern Company and Gulf Power are testing a 250 kW / 1 MWh Tesla Powerpack in Pensacola, Florida.
- Chattanooga, Tennessee’s Electric Power Board (EPB) has energized a 100kW/400kWh Vanadium flow battery.
- Entergy New Orleans paired its new 1 MW solar PV facility with a 500 kWh lithium-ion battery system.
- Arkansas Electric Cooperative Company began evaluating battery storage in 2015 for its IRP.
- Dominion Energy (Virginia) has an IRP that evaluates battery storage, and even pumped-hydro storage.
Granted, we are accustomed to the storage discussion being acceptable in the expected places – high cost regions with goals or mandates; however, the South, a historically low-cost region, has a fairly long history of energy storage projects….
