Florida utility to build world's largest solar battery; Storage costs plummet 35% in a year

Florida utility to build world's largest solar battery; Storage costs plummet 35% in a year, Apr 10, 2019

Florida's new giant battery will be charged by a solar plant and will replace fossil fuel-fired generation.

Florida Power & Light to build 409 MW solar battery

Florida Power & Light Company (FPL) is to build the world's largest energy storage battery with a capacity of 409 MW, the utility announced March 28.

The Manatee Energy Storage Center will be operational by late 2021 and will be charged by an existing solar plant in Manatee County, FPL said in a statement.

FPL supplies around 5 million customers and in January the company pledged to install 30 million solar panels in Florida by 2030 and make “unprecedented investments" in battery storage technology.

The Manatee storage facility will be located on a 40-acre site and will be able to dispatch 900 MWh of power per year.

As Florida PV penetration grows, the state will require greater energy shifting resources to mitigate the ‘duck curve’ effect on prices already experienced in California. Rapid PV growth has dampened California’s daytime power prices, raising the value of dispatchable evening peak supply.

Observations:

1. “…(FPL) is to build the world's largest energy storage battery with a capacity’ – is probably a true statement due to the prohibitive cost.  The only other storage batteries were installed in Hornsdale Wind Farm in S. Australia (a state, Adelaide is the capital).

2. “…will be charged by an existing solar plant in Manatee County, FPL said in a statement.” – that is an outright hoax, lie, misleading BS.  If solar PV in Florida is available about 20% of the time, about 5 hrs/day, that electrical energy will be used as it is produced. 

3. We just cannot eat our cake and have it too.  Charging the batteries, if and when installed, will be done, using fossil-fueled energy off the grid, which is an exercise in futility….

4. “unprecedented investments" in battery storage technology.  The Manatee storage facility will be located on a 40-acre site and will be able to dispatch 900 MWh of power per year.  – This is true, chilling to the bones.

5. 900 MWh / yr is the output of a fueled 10 MW power plant and required four (4) days operation only (10 MW X 24 hrs = 240 MWh / day.  4-day period will yield 10 MW X 96 hrs = 960 MWh.  

6. Farther calculations ferret-out the lack of value altogether.  Solar PV in Florida is available about 20% of the time on the average, per empirical production records, a whole year considered.   So, for electrical energy production of 900 MWh it requires 5 times of the 4-day period of fossil-fueled production.  In 20 days a 10 MW solar PV will generate 960 MWh.    

7. "...the ‘duck curve’ effect on prices already experienced in California. Rapid PV growth has dampened California’s daytime power prices, raising the value of dispatchable evening peak supply."  This is a very true statement - in California the evening peak hours electrical energy is retailed at $0.285 / kWh where in Texas we pay $0.099 / kWh, 1/3rd of the cost in California.  

Executive Summary:

Keep in mind that we just cannot eat our cake and have it too.  Any storage batteries in renewable energy, solar / wind - will be charged with grid supplied fossil-fueled electrical energy, which is an exercise in futility….
