    Natural Gas Killed Coal – Now Renewables and Batteries are Taking Over

    Over the past decade, coal has been increasingly replaced by cheaper, cleaner energy sources. US coal power production has dropped by 44% (866 terawatt-hours [TWh]). It’s been replaced by natural gas (up 45%, or 400 TWh), renewables (up 260%, or 200 TWh), and increased efficiency (the US uses 9%, or 371 TWh less electricity than a decade ago).

    Orsted Eyeing Solar PV, Energy Storage as Drivers for Long-Term Growth

    The CEO of Orsted, the world’s largest offshore wind developer, has said that his company is working to establish “a scalable commercial model” for solar PV and energy storage, viewing both as potential drivers of long-term growth. Danish power company Orsted, formerly known as DONG Energy until a rebrand and restructuring last year that also included selling off its oil and gas businesses, has just reported its latest quarterly financial results, including reporting for the full 2017 year.

    Putting a Value on the Resilience of Energy Storage Systems

    Findings presented in a new paper by the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL) and Clean Energy Group (CEG) show that more integrated solar photovoltaic (PV) and battery storage projects could make economic sense if the value of avoiding power outages is taken into account in project economics. Based on in-depth modeling of various building types, putting a real value on the ability of PV and storage to prevent losses during outages results in the cost-effective design of larger solar+storage systems. In some cases, putting a value on resilience can even make solar+storage projects feasible where the technologies would not be economically viable otherwise.

    New ESA White Paper Available on Interconnection Rules for Energy Storage Systems

    Over the past few years, 9 states have initiated a process to review their distribution interconnection standards to better incorporate distributed energy resources, including energy storage. While California and Hawaii are leading the way with newly developed interconnection standards, Nevada, New York, Arizona, Minnesota, Maryland, North Carolina, and Massachusetts have either put forwards draft language or initiated working groups to review existing rules and regulations.

    Arizona's 3GW Energy Storage Target, 'Clean Peak Plan' Part of a 'Wake Up Call' to Other States

    A 3,000MW energy storage target, proposed in Arizona as part of a grid modernisation policy, recognises the role of the technology in reducing the need for fossil fuels to stabilise the grid, a consultant has said. Yesterday, Andy Tobin of the state’s regulator, the Corporation Commission, presented a plan that includes a goal to generate 80% of Arizona’s power from renewable sources by 2050, a commitment to review the existing Renewable Energy Standard and Tariff (REST) policy, to use renewables to mitigate peaks establishing a ‘Clean Peak’ standard and to deploy 3,000MW of energy storage to “leverage low priced energy during the day”.

    Energy Storage Association Chief Responds to Former US Energy Secretary Comments

    Kelly Speakes-Backman, CEO of ESA told Power Engineering International, that commentators should note the continuing decline in the price of the technology, and also the need to invest more in research and development to bolster its capabilities. Professor Chu, who served during the Obama administration, was reported in the Australian as saying that the huge lithium-ion battery built in South Australia by Tesla boss Elon Musk had cost about 40 times as much as an equivalent power plant using an existing hydro-electric dam. He said while the costs of building battery plants were likely to halve over the next decade, the approach would never be cheap enough to accommodate the big seasonal shifts in renewable power production.

    Arizona Regulator Proposes Major Clean Energy Goals

    An Arizona utility regulator has made a sweeping energy policy reform proposal, which includes a call for 80% of the state’s electricity generation to come from clean energy by 2050 along with the goal of having 3 GW of energy storage deployed by 2030. Introduced by Arizona Corporation Commissioner Andy Tobin, the plan would build on the state’s current 15% by 2025 renewable energy standard established by the Arizona Corporation Commission (ACC) in 2006 and make Arizona home to some of the most aggressive clean energy and storage targets in the U.S.

    Ormat acquires US Geothermal for $110m

    Israeli geothermal energy producer Ormat Technologies Inc. announced today that it had entered into a definitive agreement to acquire US Geothermal, Inc., a renewable energy company focused on the development, production and sale of electricity from geothermal energy. Under terms of the agreement, US Geothermal shareholders will receive $5.45 per share in cash. On fully diluted basis, including payment to US Geothermal’s option holders, Ormat will pay $109.9 million. The closing of the deal is subject to customary conditions, including receipt of regulatory approvals and approval by persons holding a majority of the outstanding shares of US Geothermal common stock. The transaction is expected to close in the second quarter of 2018.

    New Batteries for Hawaiian Wind Farm: Younicos Upgrades 10 MW Energy Storage System

    AUSTIN, Texas and BERLIN, Jan. 30, 2018 - Younicos has signed an agreement with TerraForm Power to install and commission a 10 MW battery-based energy storage system upgrade at the site of the Kaheawa wind farm on the island of Maui, Hawaii. The batteries will be primarily used to provide ramping services to smooth out wind variability. The project is expected to be completed in the second half of 2018. The agreement calls for Younicos to replace existing lead-acid batteries with advanced Samsung SDI lithium-ion batteries, which will be managed by Y.Q, Younicos’s proprietary control software. Lithium-ion technology will provide a significantly higher usable energy capacity potential, as well as increase the operational lifetime of the system. It will also enable fully automated operation – with no manual battery balancing or state-of-charge management needed.

    California Pushes The Envelope on Energy Storage with Pumped Hydro

    If the blowup over President Trump’s new solar tariff proves anything, it proves that the renewable energy transition is inevitable. A new hydroelectricity project for the City of San Diego, California is a case in point. The city recently raised the level of an existing hydropower dam to hold more water, and now it is considering a massive new energy storage element that would help the grid support more wind and solar power. The project provides support for the view that the new solar tariff is little more than a “speed bump” on the road to more sustainable future. Trump’s tariff is all but certain to disrupt the lives of individual solar workers, business owners and investors to some degree, but the overall impact is beginning to look like more smoke than fire.
