Delaware has primarily focused on distributed generation and renewable energy in their passed legislative activities. The Green Energy Fund, established in 1999, was amended in 2003 and 2006 to target renewable energy technology projects and demonstrate the potential for commercialization. (29 Del. C. §8051 et seq.) Net metering had already been established in Delaware prior to 2007, but the legislature significantly expanded net metering to all customer classes in 2007 and revised limits in 2009. Then in 2009, Delaware legislature enacted solar access laws prohibiting private covenants from restricting the use of solar energy systems on residential rooftops. (145th General Assembly S.S. 1 for S.B. 49) [4, 5]
“Legislation in Delaware requires Delaware Power & Light to conduct integrated resource planning, commencing December 1, 2006. This biennial resource report requires Delaware Power & Light to project a 10-year supply and demand forecast. Additionally, Delaware Power & Light must propose the resource mix it proposes to meet its long-term obligations over the 10-year period, including the use of demand-side management programs.” 
By 2006, the Delaware Public Service Commission had approved rates for distributed generators, dealt with net metering for customers of multiple sizes and established time of use rates for customers. They had also approved demand side management for businesses and expanded it to residential customers. [2, 3]
“In January 2007, the Delaware Public Service Commission decided not to adopt PURPA Standard 14 (“Time-Based Metering and Communications”) as enacted in EPACT 2005. The Commission agreed with the assessment of the proceeding’s Hearing Examiner that based on the evidence presented the requirements of EPACT 1252 had already been met. In the Order, the Commission also decided that, relative to the state Electric Utility Retail Customer Supply Act of 2006, it will “take no action at this time regarding the feasibility of requiring advanced metering.” The Commission will not require Delmarva Power & Light (DP&L) to implement a smart-metering pilot program because DP&L voluntarily submitted in February 2007 its “Blueprint for the Future,” a “comprehensive proposal that will address issues such as the implementation in Delaware of advanced metering technology and time-based rates.”” 
As Delaware is within the PJM footprint, there is the opportunity for end-use customers to participate in demand response though curtailment service providers.
Distributed generators include qualifying cogeneration and small power production facilities.
Time-of-Use rates break the cost for electricity into periods with demand and energy priced on-peak or off-peak.
Load/demand side management credits for residential customers to de-energize and dependent on the rate either a credit to de- energize or an additional charge to business customers based on demand during a control period.
