Electric Vehicles

DER’s consist of a variety of solutions, including utility‐scale, utility‐owned, behind‐the‐meter, or customer‐owned solutions.

Customers and the Grid

New technology is changing customer expectations and grid operations, including:• Bi‐directional power flows • Co‐optimization and interoperability of 

utility‐ and customer‐owned assets• Centralized and distributed analytics• Customer assets must work safely with 

grid assets• Enhanced cyber security

Transmission Distribution

Utility operations are being transformed by new technology.  To respond to customer needs and keep providing safe, affordable, and reliable power, we need to transform 

how we think about DER’s.

• On Entergy’s distribution system today, ~100 MVA of DER generation spread out over 18,000 connections.

• These technologies include solar, batteries, and back up generators.  Many of these technologies already located at data centers, hospitals, and critical infrastructure throughout our system

• Analyze the current and future state of the distribution network accounting for:

• Future load growth• Large block loads• Voltage and loading limits• Economic and reliable power

• Typical solutions to distribution grid issues include:• Line reconductoring• Additional phases• Voltage regulators or capacitors• In cases of large growth pockets, construction of substations is also needed.

• New technologies offer a new set of tools in a distribution planners toolbox

• Using DER’s, as well as Energy Efficiency (EE) and Demand Response (DR) products, how can we best co‐optimize utility and customer owned products to create a better system?

– Improve reliability– Improve power quality– Improve the customer experience

• These new technologies require new studies and analysis beyond what traditional capacity planning has had to do.

• The purpose of Customer Product Engineering is to analyze the effects of new CIS program impacts to the distribution and transmission grids w.r.t. operating limits such as voltage, line ampacities, fault current, reverse power flows, and power quality.

• We are working with Quanta Technologies to– Develop a process to better plan and design a more dynamic 

distribution grid– Establish roles and responsibilities of organizations within Entergy 

to facilitate in data gathering and sharing to accommodate distribution planning of new programs and DER’s. 

– Learn how to incorporate new tools into our interconnection process, yearly planning cycle, and engineering analyses to safely and effectively utilize these new technologies.

• New technologies means new tools and methods of analysis• New tools are being developed that can capture changing load shapes due to customer 

programs and forecasted adoption rates, hosting capacity of distribution feeders for new DER’s, and allow customers a user friendly application process.

• These new tools and analysis will change how Entergy plans and designs its system.

enable

• Automatic application and interconnection process − From enrollment to 

energization to operation− Formulate policy positions

• Incorporate IEEE 1547 standard into the interconnection requirement− Ensure reliability and 

stability

• To properly incorporate new technologies, both planning and standardization must take place.

• Engineering plays a critical role throughout he customer product lifecycle• Leverage new tools and analysis to better understand the behavior of new 

technologies and their impacts on the grid.

• Lastly….Don’t forget about your planners!
