DATA UTILIZATION
Diversification of Power
Generation Brings Greater Need
for Data-Based Decisions
Utilities and other companies in the electric power sector are using data to solve the
dilemma of decarbonizing the power grid while also diversifying their generation
resources.
Darrell Proctor
U
tilities and power generators know
that collecting data is critical to their
operations. The process has grown
in importance as the power grid diversifies,
with more renewable energy being
added to existing thermal generation.
Software and other tools are providing
the electric power industry with more
data from a variety of sources, supporting
the ability of energy producers to make
better decisions when it comes to their
assets. Capturing real-time performance
data promotes reliability and resiliency of
the power supply, and helps optimize operations
to better serve customers.
" As the power sector decarbonizes, the
mix of generation types will change in obvious
and non-obvious ways, " said Allan
Schurr, chief commercial officer of Houston,
Texas-based Enchanted Rock, an energy
company that serves several industries
and is known for its innovative microgrid
designs (Figure 1). " The obvious changes
are increased wind and solar energy, along
with storage to time shift these variable
resources to meet load. The non-obvious
changes are the shift in conventional resources'
operation from baseload to lowcapacity
factor, dispatchable capacity to
balance supply and demand in infrequent
tail events-such as heat waves and polar
vortices-when extreme load and limited
renewables are available. "
Schurr told POWER, " In these periods,
the performance of conventional
resources must be assured and data analytics
will be needed to ensure performance
when it's needed. For example, in
extreme heat, derating of transmission
lines due to high temperatures and loading
could create a need for more local
dispatchable capacity. Likewise, extreme
cold can be difficult to forecast given
growing electric heating, so the forecast
error needs to be expanded and appropriate
