  • Another Record Year for Energy Mergers and Acquisitions
    February 15, 2016 TO: CLIENTS AND OTHER FRIENDS OF THE FIRM 2015 – Another Record Year for Energy Mergers and Acquisitions Each year around this time we take the opportunity to review the transactions and other significant industry developments over the past year and offer our views on what they may mean for the coming year. Mergers and acquisitions activity in the energy industry during 2015 was, to Contributors: say the least, robust. The low interest rate environment and favorable James H. Barkley economic conditions that contributed to record deal volume in 2014 persisted Brooksany Barrowes into 2015. With the tailwind of economic conditions and interest rates, total Emil Barth transaction volume exceeded the all-time high watermark of $184 billion established in 2014 by almost $20 billion.1 By the end of 2015, approximately Megan Berge $202 billion of transactions had been announced. 2016 also is off to a fast start William M. Bumpers with roughly $20 billion of transactions announced in the first 6 weeks of the Michael Didriksen year. Jessica Fore More than half the 2015 activity involved pipelines, midstream companies and Jerrod Harrison MLPs. In that sector, deal volume maintained its robust activity, increasing Hillary H. Holmes slightly in 2015 to $133.3 billion as compared to 130.8 billion for 2014. Transactions among regulated electric utilities notched a similarly modest William S. Lamb increase, from roughly $30 billion in 2014 to almost $34 billion in 2015. Luckey McDowell Among LDCs, volume shot up from $3.4 billion to over $18 billion, driven by Steven R. Miles transactions involving AGL Resources and Piedmont Natural Gas Company.

The views and opinions of authors ex- pressed herein do not necessarily state or reflect those of the United States Government or any agency thereof. FOREWORD It is critical to the well-being of present and future generations in Hawaii that our Islands gain greater energy self-sufficiency, primarily through the orderly, well-planned development of alternate energy resources. One of Hawaii's major alternate energy resources is geothermal energy. In the summer of 1981, Hawaii became the second State in the United States with on- line electric power generated from geothermal steam. The development of our first geothermal power plant on the Island of Hawaii has attracted worldwide interest. Our Federal Government's Department of Energy contributed much to this project and related work. One of its contributions was the preparation, by specialists with the Lawrence Berkeley Laboratory of the University of California, of this new volume, Geothermal Energy for Hawaii: A Prospectus.

  • Sempra U.S. Gas & Power and BP Wind Energy Complete Hawaii
    Sempra U.S. Gas & Power And BP Wind Energy Complete Hawaii Wind Farm ULUPALAKUA, Maui, Hawaii, Dec. 27, 2012 /PRNewswire/ -- Sempra U.S. Gas & Power and BP Wind Energy today announced the full commercial operation of the 21 megawatt (MW) Auwahi Wind facility. The power project includes eight new wind turbines on the southeast ridge of Maui's Haleakala volcano. "We are very pleased to complete construction of Auwahi Wind both on time and on budget," said Jeffrey W. Martin , president and CEO of Sempra U.S. Gas & Power. "The addition of new, clean energy from our project will be a boost for Maui's infrastructure and will help Hawaii achieve its goal of securing 40 percent of its energy from renewable sources by 2030. This project could not have been built without the enthusiastic support of the local community, the Ulupalakua Ranch and neighbors who recognize the importance of sustainable energy." The power from Auwahi Wind has been sold to Maui Electric Company (MECO) under a 20- year contract. The turbines will generate enough clean electricity to power about 10,000 typical Maui homes. An important component of the project is a 10 MW battery capable of storing 4.4 megawatt-hours of power. Energy from the battery will help regulate and sustain power to the MECO grid during light wind conditions. "Innovation is a big part of what Sempra U.S. Gas & Power brings to all of our projects," Martin said. "The battery storage component of Auwahi Wind includes state-of-the-art monitoring and safety controls which will help maximize the benefit that the Maui Electric Company and its customers receive from this project." Construction of the wind farm on Ulupalakua Ranch began in March 2012, and involved more than 180 workers.
