• Interconnection Issues - Interconnection issues arise from technical constraints and limitations in the grid infrastructure that affect the capacity, reliability, and stability of distributed energy generation systems. Distributed energy resources (DERs) such as solar photovoltaic (PV) systems, wind turbines, and battery storage require proper interconnection with the grid to inject electricity into the system and supply power to end-users. However, grid interconnection points may be limited or congested, leading to voltage fluctuations, frequency deviations, and power quality issues that can disrupt the operation of DEG systems and compromise grid stability.

  Interconnection issues can be exacerbated by regulatory barriers, administrative delays, and bureaucratic processes that impede the approval, permitting, and implementation of interconnection agreements for DEG systems. Grid interconnection procedures often involve complex technical studies, interconnection assessments, and interconnection agreements between DEG system owners and grid operators, which can be time-consuming, costly, and resource-intensive. Delays in the interconnection process can prolong project timelines, increase project costs, and deter investment in distributed energy generation, particularly for smaller-scale projects and non-traditional energy providers. Additionally, interconnection queue backlogs and capacity constraints may further exacerbate interconnection issues, limiting the ability of DEG systems to connect to the grid and access electricity markets.

  Addressing interconnection issues requires collaboration, coordination, and investment in grid infrastructure upgrades, modernization initiatives, and interconnection standards harmonization efforts. Utilities, regulators, and policymakers must work together to streamline interconnection processes, expedite interconnection approvals, and improve transparency and accountability in grid interconnection procedures.
