Storage Steps Up

Could grid-integrated batteries change the way power producers operate fossil power plants?
Could batteries affect the way power producers evaluate and operate their generating assets – in particular fossil fired generating assets they currently use to supply ancillary services? Duke Energy's Jeff Gates talks about the Notrees project and the future of battery storage.

Rooftop Tsunami

A growing wave of rooftop PV projects is starting to look ominous to some utilities. Will lawmakers accept utilities’ warnings at face value—or will they suspect they’re crying wolf?

Transition to a PV World
Sidebar Body: 

Keeping the lights on in a world of mushrooming solar rooftops requires several key technology and policy developments. During the 2012 EEI Annual Convention, panelists on a session titled “Distribution 2020: Implications of a Rapidly Evolving Distribution Grid,” offered several suggestions for managing the transition.

Technology requirements:

• Bi-directional smart grid

• New safety protocols

• Uniform interconnection standards

• Integrated distribution management systems (DMS)

Policy requirements:

• Focus incentives on installations in preferred locations

• Push the limits of demand response with direct load control

• Plan holistically—account for the total costs of distributed generation

• Apply formula rates to keep utilities whole

• Accelerate depreciation appropriately
