The main challenges in complying with interconnection regulations for solar energy revolve around delays, costs, complexity, and inconsistencies in the process:
- Lengthy Interconnection Queues and Delays: There are massive backlogs, with more than 2 terawatts of generation and storage projects waiting in interconnection queues nationwide, the majority being solar energy projects. Wait times have increased significantly (e.g., 40% increase in 2022), causing major delays in connecting solar to the grid. For example, in Washington DC, utilities like Pepco often miss regulatory deadlines for processing interconnection applications, leading to unpredictable and prolonged timelines that chill local solar markets.
- High and Increasing Costs: The costs associated with interconnection have more than doubled in recent years. These costs include expensive grid upgrades and administrative fees, which create financial uncertainty for solar developers and customers, ultimately deterring clean energy deployment.
- Complex and Non-Standardized Processes: Interconnection procedures vary widely across utilities and regions, and many rules leave room for utility discretion, which can create conflicts of interest—utilities may resist new solar projects that compete with their own generation assets. This lack of standardization and transparency complicates compliance and delays project approvals.
- Lack of Inclusion for Energy Storage: Many existing interconnection rules do not adequately address energy storage systems paired with solar, causing further delays and additional expenses for projects that aim to include battery storage.
- Utility and Safety Concerns: Utilities have concerns about maintaining grid safety and reliability as distributed solar penetration grows, which can lead to pushback and more stringent interconnection requirements, further complicating and slowing down the process.
In summary, the main challenges are lengthy and expensive interconnection queues, inconsistent and complex regulatory processes, lack of comprehensive rules for storage integration, and utility resistance due to grid management concerns. These issues collectively create significant bottlenecks that threaten to delay or limit solar energy deployment and achievement of clean energy goals.
