COVID-19/CoronaVirus Announcement

At Energize Delaware, safety is our top priority. As part of our commitment to safety, we’re closely monitoring developments related to the coronavirus (COVID-19) pandemic and taking appropriate precautions to protect the health and safety of our customers, contractors and employees. We encourage all customers and contractors to take the coronavirus seriously and to practice social distancing and personal hygeine standards.

The majority of Energize Delaware programs are still under operation and have moved all work and meetings to a virtual platform. Effective March 23, we have decided to temporarily suspend in-home appointments for the Home Energy Counseling & Check-up Program (HEC2). You can still sign-up for this important program or get more information by visiting  or by calling 855-314-9966. Once in-home appointments are restarted, we will reach out to schedule a convenient day and time.  We apologize for any inconvenience and thank you for your patience during this challenging time.

As more people are being advised to self-isolate you may be spending more time at home. Learn energy conservation tips and find resources to lower your energy costs at this link:

Through our many Energize Delaware programs, we help residents, businesses, farmers, schools, religious organizations, nonprofits, hospitals and local governments save money. We do it by providing access to high-efficiency heating, cooling, ventilation and insulation technologies at little or no cost.
