Commercial DG: Case for Financeable Contracts

Let's review factors influencing the development of distributed generation, with an emphasis on the need for financeable and deployable contracts on which DG can be financed, constructed and operated.

DG lenders and developers should consider standardizing a model form of energy service agreement.

PPL CEO Interviewed

What are the most exciting things happening at PPL? What were the biggest challenges in that journey? Were there some tough challenges you had to get through?

Threat From Behind the Meter

Behind-the-meter energy threatens the utility business model. Does history offer a lesson for crafting a response?

The case for utilities to compete directly with distributed resources.

Load as a Resource

Historically, grid operators tapped into voluntary load reduction as a last resort for keeping the lights on. But now, smart grid technologies and dynamic pricing mechanisms bring vastly greater potential for using load as a dispatchable resource. Effective implementation requires advanced technologies—and also foresight in creating programs, policies, and market mechanisms.

Capturing Distributed Benefits

The long-predicted future of distributed generation is now becoming a reality. Customers increasingly are installing and operating behind-the-meter generation systems, creating challenges and opportunities for utilities. ConEdison’s experience demonstrates the dangers and challenges, as well as the opportunities for becoming partners with utility customers.

How Con Edison Includes DG in the Forecast
Sidebar Body: 

When considering alternatives to costly infrastructure investments, the solutions are compared to the marginal cost of utility projects avoided. Traditional utility infrastructure investments to increase the marginal capacity of a distribution network can cost as little as $100/kW for substation cooling and as much as $2,000/kW for a new station build. The typical cost for DSM measures is approximately $1,000/kW.

Factors evaluated to determine use of existing DG as a reliable load reduction are:

• Area substation contingency design criteria;

• Information from specific DG units;

• Baseloaded output (kW) of each DG unit;

• Historical weekday outage rate and daily 24-hour output of each DG unit during the summer period—June, July and August; and

• Telemetry such as DG breaker status, kW and kVAR, to monitor DG performance including time of peak output coincident with the substation peak loads.

For customers with more than one generator, electrical one-line diagrams are examined to consider common-mode failures.–MJ, DL, and CR
