One of the reasons why the grid struggles to integrate modern renewable energy sources efficiently is that much of the infrastructure in the U.S. dates back to the 1950s, including transmission lines and substations. Utilities and grid operators are utilizing energy storage, often at substations along the grid, to ensure reliable and efficient electricity delivery. Over the years, OE has continued investing in the research, development, and demonstration of advanced technologies while also developing new modeling and analytics capabilities that can evolve as technology and policy needs mature. These advanced technologies include advanced sensors known as Phasor Measurement Units (PMUs) that allow operators to assess grid stability, advanced digital meters that give consumers better information and automatically report outages, relays that sense and recover from faults in the substation automatically, automated feeder switches that re-route power around problems, and batteries that store excess energy and make it available later to the grid to meet customer demand. In summary, Camus is developing the tools needed to embrace increasing amounts of distributed solar and storage as a portion of a utility’s power supply portfolio.
That means that utilities must maintain a reliable power supply as demand and use of renewables increases, provide greater transparency. The unprecedented pace of change calls for new, digital approaches to address the fundamental challenges utilities face today. Utilities must quickly integrate distributed energy resources and support surging data‑center growth.

While utilities traditionally pass infrastructure costs to ratepayers, targeted government support and developer contributions—especially when upgrades enable specific projects—are also part of the solution. “This means splitting cost among various stakeholders including utility companies, developers, ratepayers, and government funding.” “Even worse, those incumbent utilities that own both transmission and thermal generators actually benefit from the high prices caused by congestion,” said Rute, whose company is known for its AI-driven dynamic line rating technology that addresses grid bottlenecks. Who takes payment responsibility for grid upgrades is among the most-debated questions when it comes to getting more renewable energy onto the power grid. Georg Rute, CEO at Gridraven, a company founded in Estonia that has based its U.S. operations in Austin, Texas, said investment for grid upgrades should be rethought when it comes to who pays for improvements.

Without real-time insight into grid conditions, modernization investments risk delivering limited value. Modernization also maximizes existing infrastructure while building a more flexible and resilient network for the future. Modernized grids improve efficiency, reduce outages, accelerate restoration, and support the integration of distributed energy resources, including solar, wind, and battery storage.
- The grid of the future requires collaboration among engineers, cybersecurity experts, and IT professionals.
- While DERs and utility-scale renewables are often planned separately, when they’re deployed as part of a coordinated strategy, they offer a powerful tool for decarbonization and system flexibility.
- Without addressing visibility into supporting circuits, utilities risk spending capital without fully mitigating risk.
- EISA provided the legislative support for DOE’s smart grid activities and reinforced its role in leading and coordinating national grid modernization efforts.
- The bulk of these investments will go towards new customer connections and upgrading existing assets, including substations, transmission lines and hydro dams to produce power more efficiently.
To ensure reliability, utilities must be able to ensure distributed generation remains within local hosting capacity even when the grid is operating under abnormal conditions (e.g. during a partial outage). Facing likely backfeed conditions during low-demand periods, Camus will curtail solar generation when the generation-to-load ratio is greater than a preset value and the battery storage is near full. At Camus, we actively support utilities in navigating the operational impacts of distributed solar. This approach can increase hosting capacity without grid upgrades and accelerate interconnection timelines. Many utilities, especially distribution cooperatives, have power supply contracts with their generation and transmission providers that prohibit exports of excess solar power onto the transmission system.

Utilities and grid operators face several challenges when it comes to integrating renewable energy on the power grid. Another issue is that renewable resources are often located in remote or rural areas where transmission infrastructure isn’t https://neuralooms.com/articles/understanding-faecal-sludge-management/ sufficient to move electricity to where it’s needed. Investing in new transmission lines and upgrading existing ones can help deliver power from renewable energy sources to areas with high demand for electricity.

“Advanced conductors can double the capacity of existing transmission lines allowing for more electricity, including renewable energy, to be transmitted without the need for new infrastructure. Andrews said, “Renewable energy resources depend on weather conditions, which introduces a variety of technical challenges to overcome to safely connect them to the grid while maintaining stability and reliability. These sensors also provide the utility with pinpoint and instantaneous line break information for speedier outage recovery.” These are the systems that need to anticipate excess generation and charge the batteries at the most optimal time for them to be available to https://www.canisciolti.info/the-5-commandments-of-and-how-learn-more/ serve as their peak need. Now that electricity flows in multiple directions and new players like aggregators and distributed energy resources’ owners are involved, cost-sharing frameworks need to reflect the shared benefits of reliability, decarbonization, and long-term resilience.” “The traditional ‘cost-causer pays’ model was built for a centralized system and does not reflect the complexity of today’s grid.

“Meanwhile, distributed energy resource management systems DERMS give utilities the ability to control and aggregate small-scale resources like batteries and rooftop solar systems. “Platforms like advanced distribution management systems are critical for managing this data, providing operators with tools to monitor voltage, reroute power, and manage distributed generation,” said Schurko. Some of these DERs may be clustered, say at a university, as to island the campus in a microgrid, allowing the utility to shed them as a load in the moments when the generation is needed during peak conditions or lost generation.”
