    Bioenergy's role in balancing the electricity grid and providing storage options – an EU perspective Front cover information panel IEA Bioenergy: Task 41P6: 2017: 01 Bioenergy's role in balancing the electricity grid and providing storage options – an EU perspective Antti Arasto, David Chiaramonti, Juha Kiviluoma, Eric van den Heuvel, Lars Waldheim, Kyriakos Maniatis, Kai Sipilä Copyright © 2017 IEA Bioenergy. All rights Reserved Published by IEA Bioenergy IEA Bioenergy, also known as the Technology Collaboration Programme (TCP) for a Programme of Research, Development and Demonstration on Bioenergy, functions within a Framework created by the International Energy Agency (IEA). Views, findings and publications of IEA Bioenergy do not necessarily represent the views or policies of the IEA Secretariat or of its individual Member countries. Foreword The global energy supply system is currently in transition from one that relies on polluting and depleting inputs to a system that relies on non-polluting and non-depleting inputs that are dominantly abundant and intermittent. Optimising the stability and cost-effectiveness of such a future system requires seamless integration and control of various energy inputs. The role of energy supply management is therefore expected to increase in the future to ensure that customers will continue to receive the desired quality of energy at the required time. The COP21 Paris Agreement gives momentum to renewables. The IPCC has reported that with current GHG emissions it will take 5 years before the carbon budget is used for +1,5C and 20 years for +2C. The IEA has recently published the Medium- Term Renewable Energy Market Report 2016, launched on 25.10.2016 in Singapore.

  • A New Era for Wind Power in the United States
    Chapter 3 Wind Vision: A New Era for Wind Power in the United States 1 Photo from iStock 7943575 1 This page is intentionally left blank 3 Impacts of the Wind Vision Summary Chapter 3 of the Wind Vision identifies and quantifies an array of impacts associated with continued deployment of wind energy. This 3 | Summary Chapter chapter provides a detailed accounting of the methods applied and results from this work. Costs, benefits, and other impacts are assessed for a future scenario that is consistent with economic modeling outcomes detailed in Chapter 1 of the Wind Vision, as well as exist- ing industry construction and manufacturing capacity, and past research. Impacts reported here are intended to facilitate informed discus- sions of the broad-based value of wind energy as part of the nation’s electricity future. The primary tool used to evaluate impacts is the National Renewable Energy Laboratory’s (NREL’s) Regional Energy Deployment System (ReEDS) model. ReEDS is a capacity expan- sion model that simulates the construction and operation of generation and transmission capacity to meet electricity demand. In addition to the ReEDS model, other methods are applied to analyze and quantify additional impacts. Modeling analysis is focused on the Wind Vision Study Scenario (referred to as the Study Scenario) and the Baseline Scenario. The Study Scenario is defined as wind penetration, as a share of annual end-use electricity demand, of 10% by 2020, 20% by 2030, and 35% by 2050. In contrast, the Baseline Scenario holds the installed capacity of wind constant at levels observed through year-end 2013.

  • PURPA and Solar by Robert Shapiro, in Washington
    April 2017 PURPA and Solar by Robert Shapiro, in Washington Solar developers are again using a 1978 federal law that requires utilities to sign long-term power purchase agreements to secure utility PPAs after years of disuse, but the recent track record of developers trying to use this statute is mixed. The law, called the Public Utility Regulatory Policies Act or PURPA, requires utilities to buy electricity from renewable energy projects of up to 80 megawatts in size at the “avoided cost” the utility would otherwise spend to purchase or generate the electricity itself. PURPA is expected to overtake state renewable portfolio standards as the biggest driver for utility-scale PPAs in 2017 due to falling solar electricity prices. Solar electricity can now be delivered at less than utility avoided costs in such states as North Carolina, Georgia, Utah and Oregon. Any developer planning to use PURPA should analyze first how likely it is to end up bat- tling with the utility before the state public utility commission and, if so, with what likeli- hood of success. Potentially Useful Tool For more than 10 years, renewable energy developers have relied on renewable portfolio standards, or RPS, created under state laws as the primary way to get a utility to enter into a long-term PPA that can support project financing. Twenty-nine states and the District of Columbia have RPS standards. However, as most of the state utilities in RPS states have signed / continued page 2 IN THIS ISSUE 1 PURPA and Solar 6 Emerging Storage A TAX EQUITY TRANSACTION was set aside on audit.

  • Electric Power Grid Modernization Trends, Challenges, and Opportunities
    Electric Power Grid Modernization Trends, Challenges, and Opportunities Michael I. Henderson, Damir Novosel, and Mariesa L. Crow November 2017. This work is licensed under a Creative Commons Attribution-NonCommercial 3.0 United States License. Background The traditional electric power grid connected large central generating stations through a high- voltage (HV) transmission system to a distribution system that directly fed customer demand. Generating stations consisted primarily of steam stations that used fossil fuels and hydro turbines that turned high inertia turbines to produce electricity. The transmission system grew from local and regional grids into a large interconnected network that was managed by coordinated operating and planning procedures. Peak demand and energy consumption grew at predictable rates, and technology evolved in a relatively well-defined operational and regulatory environment. Ove the last hundred years, there have been considerable technological advances for the bulk power grid. The power grid has been continually updated with new technologies including increased efficient and environmentally friendly generating sources higher voltage equipment power electronics in the form of HV direct current (HVdc) and flexible alternating current transmission systems (FACTS) advancements in computerized monitoring, protection, control, and grid management techniques for planning, real-time operations, and maintenance methods of demand response and energy-efficient load management. The rate of change in the electric power industry continues to accelerate annually. Drivers for Change Public policies, economics, and technological innovations are driving the rapid rate of change in the electric power system. The power system advances toward the goal of supplying reliable electricity from increasingly clean and inexpensive resources. The electrical power system has transitioned to the new two-way power flow system with a fast rate and continues to move forward (Figure 1).
