EnergyPATHWAYS
EnergyPATHWAYS (EP)—a bottom-up energy sector tool with stock-level accounting for all consuming, producing, delivering, and converting energy infrastructure—provides an analytic backbone to create electric technology adoption and power consumption scenarios.
Demand-Side Grid Model (dsgrid)
NREL's demand-side grid (dsgrid) model harnesses decades of sector-specific energy modeling expertise to understand current and future U.S. electricity load for power systems analyses.

7. Demand-Side Modeling Challenges
Models are complex.
Takes time to develop modeling data and expertise in using the tools.
EnergyPATHWAYS is open-source, but underlying data is not.
Dsgrid is not publicly available.
Not enough time in the WECC 2019 Study Program to create demand-side scenario models from scratch.

8. Demand-Side Modeling Solution
NREL has already done the bulk of the work for us in the creation of an ensemble of Demand-side Scenarios that we can use as a potential starting point for the WECC demand-side scenarios.
These NREL demand-side scenarios were used in the Electrification Futures Study and the Energy-Water-Climate Change (EWCC) study.

36. NREL Electrification Futures Study
Through the Electrification Futures Study (EFS), the National Renewable Energy Laboratory is exploring the impacts of widespread electrification in all U.S. economic sectors.
In this multi-year study, NREL and its research partners—Electric Power Research Institute, Evolved Energy Research, Lawrence Berkeley National Laboratory, Northern Arizona University, and Oak Ridge National Laboratory—are using multiple analytic tools and models to develop and assess electrification scenarios designed to quantify potential energy, economic, and environmental impacts to the U.S. power system and broader economy.

38. Demand-Side Scenarios
Released June 2018, the second report in the EFS series aims to support an integrated understanding of how the potential for electrification might impact the demand side of the U.S. energy system. The report presents scenarios with various degrees of future electrification in all major end-use sectors of the U.S. energy system and quantifies impacts on the amount and shape of electricity demand.

39. Foundational Technology Cost and Performance Data
Released December 2017, the first report in the EFS series provides estimated cost and performance data for electric technologies considered in the study. The study applies a literature- and expert opinion-based approach in developing future projections of technology advancement to be used in the EFS scenario analysis. The data can also inform other researchers and analysts exploring electrification.

40. Battery Storage
NREL: The Potential for Battery Energy Storage to Provide Peaking Capacity in the United States
Providing peaking capacity could be a significant U.S. market for energy storage. Of particular focus are batteries with 4-hour duration due to rules in several regions along with these batteries’ potential to achieve life-cycle cost parity with combustion turbines compared to longer- duration batteries. However, whether 4-hour energy storage can provide peak capacity depends largely on the shape of electricity demand—and under historical grid conditions, beyond about 28 GW nationally, the ability of 4-hour batteries to provide peak capacity begins to fall.
