Storage: The Macro and Micro
Transformation of Electric Grids
Te transmission industry enters 2014 with a
lot of work ahead as it continues to recreate the
grid and make it more renewable energy-ready.

On the macro level, transmission lines are being developed
worldwide to move green power long distances from remote
regions to power-hungry population centers. On the more
micro level, new energy storage systems are helping grid operators fne-tune their management of wind and solar variability. Energy storage is a natural partner to renewable energy
since it evens the peaks and valleys created by wind and solar
production on the grid.
The rise of energy storage
comes with an accompanying focus on microgrids, self-contained entities that can
island from the main grid
during power outages or can
feed the grid special services when connected. Energy
storage often is a key element
