  • Trends in Electricity Prices During the Transition Away from Coal by William B
    May 2021 | Vol. 10 / No. 10 PRICES AND SPENDING Trends in electricity prices during the transition away from coal By William B. McClain The electric power sector of the United States has undergone several major shifts since the deregulation of wholesale electricity markets began in the 1990s. One interesting shift is the transition away from coal-powered plants toward a greater mix of natural gas and renewable sources. This transition has been spurred by three major factors: rising costs of prepared coal for use in power generation, a significant expansion of economical domestic natural gas production coupled with a corresponding decline in prices, and rapid advances in technology for renewable power generation.1 The transition from coal, which included the early retirement of coal plants, has affected major price-determining factors within the electric power sector such as operation and maintenance costs, 1 U.S. BUREAU OF LABOR STATISTICS capital investment, and fuel costs. Through these effects, the decline of coal as the primary fuel source in American electricity production has affected both wholesale and retail electricity prices. Identifying specific price effects from the transition away from coal is challenging; however the producer price indexes (PPIs) for electric power can be used to compare general trends in price development across generator types and regions, and can be used to learn valuable insights into the early effects of fuel switching in the electric power sector from coal to natural gas and renewable sources. The PPI program measures the average change in prices for industries based on the North American Industry Classification System (NAICS).

All Rights Reserved. This report is available on the Pennsylvania Environmental Council website: http://www.pecpa.org/roadmap Cover image credit: Nicholas A. Tonelli 130 Locust Street Suite 200 Harrisburg, PA 17101 T 717.230.8044 F 717.230.8045 www.pecpa.org Executive Summary Now is the time for action on climate change. The rising concentration of greenhouse gases (GHG) poses a multitude of risks to Pennsylvania and to our planet as a whole. Reducing those risks requires that, in the coming decades, we make significant cuts in emissions of greenhouse gases on a global scale. No state (and indeed no nation) can solve this problem on its own, but Pennsylvania can play an important role in addressing climate change, the most challenging environmental issue of our time. Addressing this issue is also essential to the long-term economic and geopolitical stability of the nation. Currently, Pennsylvania is responsible for about one percent of the worldwide emissions of GHG. This level of emissions ranks third among U.S. states, and puts Pennsylvania in the league of the top 25 emitting nations in the world. Challenges often bring opportunities, and the challenge of reducing GHG emissions brings opportunities related to which states will benefit the most from the growth of the clean technology industries that will solve the climate change problem. According to a May 2006 Cleantech Capital Group Report, venture capitalists invested $1.6 billion in North American clean technology companies in 2005, an increase of 43% from 2004.

  • Hydroelectric Power -- What Is It? It=S a Form of Energy … a Renewable Resource
    INTRODUCTION Hydroelectric Power -- what is it? It=s a form of energy … a renewable resource. Hydropower provides about 96 percent of the renewable energy in the United States. Other renewable resources include geothermal, wave power, tidal power, wind power, and solar power. Hydroelectric powerplants do not use up resources to create electricity nor do they pollute the air, land, or water, as other powerplants may. Hydroelectric power has played an important part in the development of this Nation's electric power industry. Both small and large hydroelectric power developments were instrumental in the early expansion of the electric power industry. Hydroelectric power comes from flowing water … winter and spring runoff from mountain streams and clear lakes. Water, when it is falling by the force of gravity, can be used to turn turbines and generators that produce electricity. Hydroelectric power is important to our Nation. Growing populations and modern technologies require vast amounts of electricity for creating, building, and expanding. In the 1920's, hydroelectric plants supplied as much as 40 percent of the electric energy produced. Although the amount of energy produced by this means has steadily increased, the amount produced by other types of powerplants has increased at a faster rate and hydroelectric power presently supplies about 10 percent of the electrical generating capacity of the United States. Hydropower is an essential contributor in the national power grid because of its ability to respond quickly to rapidly varying loads or system disturbances, which base load plants with steam systems powered by combustion or nuclear processes cannot accommodate. Reclamation=s 58 powerplants throughout the Western United States produce an average of 42 billion kWh (kilowatt-hours) per year, enough to meet the residential needs of more than 14 million people.

  • 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).
