WHAT IS GWDC?
GWdc, or gigawatts of direct current, is not to be confused with GW. While both metrics measure power capacity, GWdc is specific to solar energy.
The output of solar panels can vary depending on cloud coverage, the time of year, wind, temperature or the quality and age of the equipment, but GWdc measures the capacity of photovoltaic arrays working at maximum efficiency.
GWdc can be thought of as a car driving at top speed. Solar panels will only be able to generate that much capacity if all the conditions are right.
Once all three phases are complete the facility will deliver 2.5GWdc of solar generation alongside 2.9GWh of battery storage – enough, according to Google, to power more than 315,000 Arkansas homes each year.
Kate Brandt, Google’ s Chief Sustainability Officer, highlights the importance of combining both generation and storage at Steel River.
“ By pairing massive solar arrays with battery storage, the project can store the sun’ s peak daytime output and feed it back into the grid exactly when it’ s needed most,” she says.“ This creates a more reliable, resilient grid that can meet rising electricity demand while keeping power affordable for everyone.”
