Transmission and energy storage are centerpiece policies designed to address extreme weather and an evolving resource mix. Electric vehicles (EVs), which could represent up to 27% of global electricity demand by 2050, add an often overlooked option to cost-effectively enhance grid resilience and flexibility. If transmission transmits electricity across land, and batteries absorb and release…

The “grid of the future” is increasingly the grid of the present – at least in places like California, Texas, Hawaii, and Australia. Customer devices are playing an active role in power supply and grid stability – as demonstrated by the nearly 1GW of behind-the-meter batteries supporting California’s recent peak event. Yet, transmission and distribution…

The way that demand flexibility and distributed resources are modelled in resource adequacy has a significant impact on resource adequacy. That impact will grow over time as decentralization of the power system continues apace. Resource Adequacy Is About the Ability to Avoid Load Shedding Grids have inherited a resource adequacy assessment framework that has been…

On Sunday, 11 October 2020, South Australia made international headlines when it became the first interconnected power system of its size (1 to 3 GW) to have 100% of its demand met by 100% solar photovoltaics (PV). While this included centrally dispatched utility PV, the vast majority (76%) of the PV generation online was distributed…

Most jurisdictions in the PJM region, which spans 13 states and Washington, D.C., have some sort of renewable energy goals. This is reflected in our interconnection queue, where renewable resources and storage account for over 95% of new service requests. As emerging trends swiftly reshape the traditional energy landscape, PJM is committed to facilitating grid…

Finding ways to scale up distributed energy resources (DERs) in addition to utility-scale renewable resources is imperative to meet our decarbonized vision. Many know that Hawaiian Electric’s system already has a high penetration of DERs, and we continue to lead the nation in developing solutions to manage the continual increase. To meet our 2030 climate…

Climate goals and resulting legislation have pushed the European electricity and gas transmission system operator associations (ENTSOs) to increase collaboration on joint infrastructure planning for almost a decade. Visible success can be seen in the ENTSOs joint scenarios for infrastructure planning. This year’s dramatic developments with a war in Europe turned some basic paradigms and…

Some topics are exciting to discuss for everybody. Others, well, it takes a select few who can call on their inner geekiness to appreciate. Operating reserve fits that category. It is resource adequacy’s “here and now” operational cousin — capacity above or below what is needed to meet the anticipated system conditions, used during operational…

Grid-forming (GFM) technology is one of the latest hot topics in power systems, and for good reason. Although it isn’t technically new, modern applications of GFM technology are showing incredible potential for solving some of the most difficult problems we face in power systems with high shares of inverter-based resources (IBRs). GFM controls can provide…

Distribution System Data Electric vehicles (EVs), demand response, and distributed energy resources have all increased bi-directional interactions and the complexity of the power grid between the substation and the customer. Correctly managing these resources and understanding their impact requires detailed models of the electrical distribution system. However, data on U.S. distribution systems are poor. Until…
