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

Harvey Hanna & Associates has agreed to install rooftop solar on eight of its properties with King Energy, covering more than 1.8 million square feet of rooftops and more than 19 megawatts of direct current. The eight projects are still in development, and King Energy's four projects were accepted into Governor Meyer's JobsFirst Permitting Accelerator.

Why it matters

Delaware generates less electricity than it uses and imports a large share of its power through the PJM Interconnection grid, while state law requires utilities to get 40% of their power from renewable energy by 2035. For Delaware households, the projects matter because local solar capacity can reduce reliance on imported power as the state works toward that deadline.

The portfolio covers more than 1.8 million square feet of rooftops and more than 19 megawatts of direct current across eight properties. Named sites include 750 Governor Lea Rd. and 400 Ships Landing Way in New Castle, and a 1.3 million square-foot warehouse complex is planned near Jamison Corner and Scotts Run in Middletown.

The players

Harvey Hanna & Associates

A Delaware and Maryland industrial and commercial property owner and manager with nearly 4 million square feet of space.

King Energy

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

Governor Meyer

Delaware's governor, whose JobsFirst Permitting Accelerator accepted King Energy's four projects.

The details

King Energy is a venture-backed commercial solar company that builds, owns and operates rooftop solar on multi-tenant properties, so the arrangement places the solar systems on Harvey Hanna's buildings while King Energy handles the installation and operation. Utility providers typically comply with renewable standards by buying renewable energy credits or solar renewable energy credits, which is how commercial rooftop projects like these can count toward the state's requirement. Harvey Hanna, which owns and manages nearly 4 million square feet of industrial and commercial space in Delaware and Maryland, also acquired 103 acres in Middletown for $25 million this summer as part of its development pipeline.

Timeline

  1. 2024: Delaware's net generation measured at about 4.8 million megawatt-hours.

  2. Summer 2026: Harvey Hanna acquired 103 acres in Middletown for $25 million.

  3. November 2, 2026: Harvey Hanna and King Energy's rooftop solar agreement was announced from Newport.

  4. 2035: State deadline for utilities to source 40% of power from renewable energy.

The Home Front

The projects sit within Delaware's effort to meet a 40% renewable electricity standard by 2035 while the state imports a large share of its power through the PJM grid. Commercial rooftop arrangements like this one are a growing share of the local solar landscape as landlords and developers look to put unused roof space to work.

If you rent or own a commercial space in Delaware, ask your landlord or property manager whether rooftop solar is planned and whether it would affect roof access or building maintenance. Any solar installation on a roof should be planned and installed by a licensed contractor, and questions about lease terms or transaction decisions should go to a licensed attorney or real estate agent.

The takeaway

Rooftop solar on commercial buildings is one way Delaware is working toward its 40% renewable requirement, and the projects' progress will show how much new local generation the state gains. Keep an eye on whether the eight projects move from development into construction over the coming years.
