Designing the PR100 Study: Puerto Rico Grid Resilience and Transition to 100% Renewable Energy

[1]: The territory must investigate how renewable energy and other generation technologies can be implemented with energy storage, distributed generation, distribution control, electric vehicles, and energy efficient and responsive loads in each of Puerto Rico's cities and towns to help promote widespread end-use electrification to meet these targets and foster widespread end-use electrification. [1]] The U. S. Department of Energy, National Renewable Energy Laboratory, Lawrence Berkeley National Laboratory, and Sandia National Laboratories' proposal to quantify 100% renewable energy pathways using an integrated analysis approach. Puerto Rico's renewable energy goals should assist the island's renewable energy goals; help ensure energy system stability against future extreme weather events; and provide input into LUMA Energy's collaborative planning roadmap. This talk will outline the next steps in preparing a two-year study entitled Puerto Rico Grid Resilience and Transitions to 100% Renewable Energy.

Pandemic, War, and Global Energy Transitions

Global demand, oil price shocks, disruptions in energy supply chains, and hampered energy investment were all affected by the pandemic, leading to dramatic fluctuations in energy demand, oil price shocks, disruptions, disruptions in electricity chains, and reduced energy supply chains, as a result of the war left the world with energy price hikes and energy security challenges. By reviewing new studies and consulting consultants in the field, this paper examines the effects throughout the energy system, including upstream fuel supply, renewable energy development, demand for energy services, and implications for energy equity. Both crises appeared as opportunities for low-carbon energy transitions: the pandemic by demonstrating the full extent of lifestyle and lifestyle change in a short period, as well as the importance of science-based policy guidance, and the war by stressing the need for greater energy diversification and reliance on local, renewable energy sources. As such, the fossil fuel industry could become even more popular after these energy crises that have brought new lock-ins.

Achieving 50% Energy Savings in Chicago Homes: A Case Study for Advancing Equity and Climate Goals

Since 2004, the National Renewable Energy Laboratory and Elevate have collaborated to find pathways to deep energy retrofits in Chicago's housing market, document equity implications, and co-benefits of this transition, and validate the findings by installing retrofits in real Chicago homes. The Residential Buildings team at NREL maintains the best-in-class ResStock2122 energy model of the U. S. residential building stock, according to the company's Residential Buildings group. We calibrated ResStock to Chicago's unique local housing stock to accurately simulate energy usage in Chicago households under both current and modified retrofit scenarios. We simulated a large variety of potential building retrofits based on residential energy use, then grouped them into bundles based on utility and utility bill savings. ResStock can model various building styles and housing characteristics, so we're able to see the variety of outcomes that could occur if these upgrades were applied throughout the entire housing market. By comparing the estimated energy use before and after a retrofit, we can then estimate future energy savings from Chicago's housing stock. This report, among other aspects of the project, contributes to the following objectives: Specifically, this work aids in the following project objectives: Develop a building retrofitting process for Chicago single-family and 2-unit buildings; Identify communities and home types that have the greatest chance of savings from electrification; and Assess the effects of advanced building retrofits on energy use, utility bills, and CO2 emissions at the city and building level; and Assess the effects of advanced building retrofits on energy use,.

Assessing the Interactive Impacts of Energy Efficiency and Demand Response on Power System Costs and Emissions

However, the specific EE and DR capabilities that may be most appropriate, as well as the interplay between evolving EE and DR resource potentials, as well as associated utility system impacts, are not well understood. Based on changes in generation expansion, transmission expansion, and dispatch patterns, we can determine the effects of EE and DR in isolation and in combination on bulk power system costs and emissions. Comparing to more commonly used utility strategies that only consider supply-side resources, the study methodology mimics utility resource planning and uses more sophisticated methods to choose least-cost generation and transmission capacity from supply-and-demand-side resources.

Net Zero World Initiative: Accelerating Global Energy System Decarbonization

The United States, partner countries, and philanthropies are united to accelerate the transition to renewable, secure energy sources and build a Net Zero World. The Net Zero World Initiative promotes decarbonization of global energy systems by leveraging experience from U. S. government departments and the Department of Energy national laboratories, as well as other governments and philanthropies, in partnership with other international and philanthropies.

Community Energy Planning: Best Practices and Lessons Learned in NREL's Work with Communities

Communities are on the ground for a surge in clean energy deployment. Through interviews with senior NREL practitioners and a study of the literature on equitable community planning, NREL created this best-practices paper to inform and enhance NREL's community energy planning capabilities while also providing a resource for others working in this sector. The findings include five best practices for community energy planning, which NREL researchers can use to improve the effectiveness of their work.

The Effect of Inverter Loading Ratio on Energy Estimate Bias: Preprint

We take an alternative route in this paper, using real system power measurements to show that energy estimates from traditional industry models suffer from a bias that increases with increasing inverter loading ratios. We also show that this loading ratio-dependent bias is highly correlated with an empirical subtraction bias obtained from real power plant results.

Clean Energy Transition for Transportation Systems: Modeling Implications

Transportation is now the least diversified energy demand segment, with over 90% of energy usage coming from petroleum. Transportation as a result, has been the most significant source of GHG emissions in the United States, and passenger and freight's transportation demands are increasing rapidly. New analytical modeling and evaluation are required to explore the clean energy transition for the multitude of different transportation modes. This talk explored recent work at the National Renewable Energy Laboratory to discover and use cutting-edge technologies and analytics techniques to aid the transition to a sustainable mobility future and the integration of transportation systems with the wider energy market.

Advances in Energy Hybridization for Resilient Supply: A Sustainable Approach to the Growing World Demand

According to the World Health Organization, household air pollution from inefficient stoves causes more premature deaths than malaria, tuberculosis, and HIV/AIDS. Resilient Hybrid Energy Systems, which provide cleaner electricity by combining wind, solar, and biomass energy with traditional fossil energy, increasing production quality and stability, and lowering generation costs and emissions, fueling the need for reliable electricity and reducing emissions. Microgrids have been shown as an effective way to implement RHES, with others focusing specifically on reducing the environmental impact of electric power generation.

Check the Storage Stack: Comparing Behind-the-Meter Energy Storage State Policy Stacks in the United States

It is therefore uncertain what BTM storage policies are adopted across the region, what should be a complete storage policy framework or stack, or how state policies compare to the stack. This first-of-its-kind BTM storage policy stack includes 11 key policy areas, as well as 31 related policies divided across market plan, development, and expansion policy components.
