Insufficient grid-supporting capabilities, such as reactive power, are causing limitations on the approval of new storage connections in specific areas. The expansion of storage infrastructure is encountering limitations due to congestion in local transmission and distribution networks. Unlike generators, storage systems often provide multiple services simultaneously, such as energy arbitrage, frequency response, and voltage control, which complicates grid operator scheduling and settlement protocols. Variations in telemetry interfaces across different systems can create challenges for achieving instantaneous grid dispatch. Efforts to establish unified models for distributing system operations face hurdles from older, existing IT infrastructure. The implementation of updated operational standards is often slowed by inconsistent approaches to data governance. Fragmented systems in the energy sector create operational barriers, delaying the adoption of real-time management. Consequently, even technically viable storage projects may deliver suboptimal returns if unable to access dynamic market signals or respond to grid needs with millisecond precision, undermining investor confidence in near term scalability.
