King Energy has successfully raised $10 million to accelerate the growth of its solar financing and billing platform tailored for multi-tenant commercial buildings. This funding will enhance the company’s operations and support its expansion across North America.
Business Model Overview
King Energy’s innovative business model involves:
- Utilizing Unused Space: The company rents out unused roof or parking lot space on commercial buildings to install solar panels.
- Energy Sales: It sells the energy produced by these solar panels to building tenants and other customers, profiting from the difference between operational costs and revenue from energy sales.
- Simplified Leasing: King Energy offers straightforward roof leases without requiring tenant improvements or investments from landlords, providing them with immediate rental income [1].
Addressing Renewable Energy Challenges

The importance of renewable energy is growing among building owners and facility managers, driven by local laws and corporate sustainability targets. However, the split incentive gap—where landlords pay for energy efficiency upgrades while tenants benefit from lower costs—remains a significant barrier to decarbonizing buildings. King Energy’s approach helps bridge this gap by providing a consolidated monthly energy bill that combines on-site solar and utility-supplied electricity charges through its OneBill platform [1].
Expansion Plans and Funding Details
The recent funding round includes:
- $7 million from ArcTern Ventures
- $3 million from Blackhorn Ventures, Active Impact Investments, and Next Frontier Capital
This investment will enable King Energy to scale its operations, enhance technology, and hire additional staff, focusing on states with successful community solar programs such as New Jersey, Maryland, New York, Massachusetts, and Illinois [1].
Market Demand and Future Outlook
King Energy currently manages nearly 200 energy programs across multi-tenant commercial properties, serving over 25 million square feet of tenant space. The company has collaborated with more than 2,000 businesses across nine states, with strong demand observed in neighborhood shopping centers and large commercial facilities like distribution centers and warehouses [1].
The company’s model is similar to that of other energy-as-a-service providers, such as Budderfly, which also focuses on energy efficiency upgrades at no cost to property owners. Budderfly has projected nearly $200 million in annual recurring revenue for 2024, highlighting the growing market for energy management solutions [1].
Conclusion
King Energy’s recent funding and innovative approach position it well to capitalize on the increasing demand for renewable energy solutions in commercial real estate. By addressing the challenges of energy procurement and providing financial benefits to landlords and tenants alike, King Energy is paving the way for a more sustainable future in the energy sector.
