Just like the small however mighty falcon it’s named after, Kestrel is sharp-sighted, sensible,
and quick. These qualities will probably be instrumental in NREL’s means to leverage cutting-edge
capabilities, from AI and machine studying to superior information visualization, to construct
on the progress of the previous decade and increase the impression of successive HPC investments.

Mixed with the newest NREL-developed modeling improvements, resembling Advanced Research on Integrated Energy Systems, Simulation and Emulation for Advanced Systems, and Sienna, these new HPC capabilities will allow NREL researchers to carry a 100% carbon-pollution-free
future into focus with pace and precision.

“We now have unprecedented entry to information data measurements coming from electrical
energy grids,” Kroposki mentioned. “And we will use superior machine studying strategies
to extract salient factors from these huge quantities of knowledge, improve how we mannequin
energy methods, and study responses to conditions to assist energy system operators enhance
operations in actual time.”

Onward and Upward

Kroposki has seen NREL’s grid integration work evolve from including tiny quantities of
wind and photo voltaic to small stand-alone methods to charting viable pathways to 100% renewable
electrical energy.

“After I began, I might get laughed out of rooms for even citing 2% wind and photo voltaic,”
he mentioned. “And within the final decade, we have seen large strides and utilities saying
100% clear power targets.”

A decade in the past, little within the present power panorama foreshadowed such a seismic
shift, a lot much less the meteoric rise of renewables. Coal equipped the lion’s share of
U.S. electrical energy. In contrast, photo voltaic and wind generated lower than 3% mixed. Even
within the best-case state of affairs NREL had thought of at that time, renewable power may
generate 80% of U.S. electrical energy by 2050.

Now the findings of the 2012 Renewable Power Futures Examine—which struck many trade
specialists as overly optimistic then—appear conservative in gentle of current scientific
advances and present market realities. At the moment, 1 / 4 of U.S. electrical energy comes
from renewable assets, primarily photo voltaic and wind. And coal’s share has plummeted
by greater than half, a development that’s anticipated to proceed.

We now have crossed the edge, and the journey continues. There are obstacles to beat
and selections to be made—sensible selections pushed by laborious information. And time is of the essence.

As HPC methods proceed to scale by orders of magnitude within the decade forward, NREL
researchers can stay up for including much more complexity to their fashions and simulations,
fixing greater issues quicker, and rising the momentum of the power transition.
