Working at the Edge of the Grid

How to find value in distributed energy resources.

Distributed resources create a new multi-directional power grid, achieving the sort of scale-driven cost levels and ease of installation that portend of future mass deployment.

Embracing Disruption

Developing a leadership role for utilities in alternative technologies.

Faced with aging assets, rising operating costs, growing regulatory risks, and flat demand growth, utilities are challenged to remain competitive in an evolving energy market. The answer might be for utilities to establish a leadership position and pursue a more flexible mission.

Taming Distributed Energy

How advanced distribution management systems are key to integrating distributed resources.

Fast growing distributed resources create technical challenges for utilities. Advanced DMS technology promises to help keep local grids balanced.
