Should Delaware businesses be required to produce more of their own clean power?

Harvey Hanna & Associates has agreed to install rooftop solar on eight properties with King Energy, covering more than 1.8 million square feet of rooftops. The eight projects remain in development.

Why it matters

Delaware generates less electricity than it uses and imports a large share of its power through the PJM Interconnection grid. The projects would supply about 2.2% of the energy needed to meet the state's requirement that utilities get 40% of their power from renewables by 2035.

The portfolio spans more than 1.8 million square feet of rooftops and totals over 19 megawatts of direct current. Projected output from three named sites is 14.7 million kilowatt-hours annually, though the eight projects remain in development.

The players

Harvey Hanna & Associates

A Delaware and Maryland real estate firm that owns and manages nearly 4 million square feet of industrial and commercial space.

King Energy

A venture-backed commercial solar company that builds, owns and operates rooftop solar systems on multi-tenant properties.

The details

King Energy, a venture-backed commercial solar company that builds, owns and operates rooftop solar on multi-tenant properties, will install the systems. The named sites include 750 Governor Lea Rd. and 400 Ships Landing Way in New Castle, while Harvey Hanna is also planning a 1.3 million square-foot warehouse complex near Jamison Corner and Scotts Run in Middletown.

2024: Delaware measured net generation of about 4.8 million megawatt-hours.
Summer 2026: Harvey Hanna acquired 103 acres in Middletown for $25 million.
2035: State requirement for utilities to source 40% of power from renewables takes effect.

Roadmap

The project would supply about 2.2% of the energy needed to meet Delaware's 40% renewable requirement set for 2035. It illustrates how commercial rooftop solar is being positioned as one piece of the state's effort to reduce reliance on imported power through the PJM grid.

For commercial tenants and property owners in the Delaware and Maryland region, rooftop solar installations can change the energy profile of multi-tenant buildings. The eight projects remain in development, so the practical effects on electricity costs and building operations are not yet clear.

The takeaway

Commercial rooftop solar is emerging as a way for property owners to add generation capacity without new land. As Delaware works toward its 2035 renewable standard, projects like this one show how private real estate could play a role in meeting state energy goals.
