      1. Costs Continue to Decline for Residential and Commercial Photovoltaics in 2018

        Costs Continue to Decline for Residential and Commercial Photovoltaics in 2018

        Continuing an annual NREL cost benchmarking effort that began in 2010, “U.S. Solar Photovoltaic System Cost Benchmark: Q1 2018,” found installed costs of PV systems declined across two of three sectors in the first quarter of 2018 from a year earlier. The other report, “2018 U.S. Utility-Scale Photovoltaics-Plus-Energy Storage System Cost Benchmark,” establishes NREL’s first benchmark of PV-plus-storage costs. Both reports and their models can be used to estimate future cost-reduction opportunities for PV and PV-plus-storage systems, helping to guide research and track costs.

        El Paso Electric Taps 100MW of Storage to Supply West Texas Summer Peaks

        El Paso Electric wants to build new natural-gas generation to meet its summer peaks, but it also selected solar and, unusually for Texas, energy storage resources. The portfolio's heavy battery component breaks new ground for Texas, a massive energy market where energy storage has had an exceedingly difficult time breaking in, as previously reported by GTM. A few battery projects have moved forward as research efforts, and some have succeeded with creative business models, but never before on the scale of 100 megawatts.

      3. 'Unlayering' Peak Demand Could Accelerate Energy Storage Adoption

        'Unlayering' Peak Demand Could Accelerate Energy Storage Adoption

        The debate over energy storage replacing gas-fired peakers has raged for years, but a new approach that shifts the terms of the argument could lead to an acceleration of storage deployments. Rather than looking at peak demand as a single mountainous peak, some analysts now advocate a layered approach that allows energy storage to better match peak needs. The idea is beginning to gain traction with some states and utilities.

        Invenergy Begins Operation of Utility-Scale Energy Storage System

        Invenergy has begun commercial operations of a utility-scale battery storage system located in Knoxville, Iowa, developed for MidAmerican Energy. This followed a four-month construction process that culminated with the battery becoming operational in December 2018. The battery can provide four MWh of storage capacity, supplying one MW of power for up to four hours—enough electricity to power about 900 average Iowa homes.

      6. Solar + Storage Half The Cost Of Gas Peaker Plants — 8MinuteEnergy

        Solar + Storage Half The Cost Of Gas Peaker Plants — 8MinuteEnergy

        S&P Global reports the cost of solar with battery backup dropped precipitously in 2018. Several tenders for solar plus storage came in at under $30 per megawatt-hour last year. Stand alone prices for installed battery storage — based on a 20 megawatt-hour system with 4 hours of storage — dropped 40% from the previous year to $357 per kilowatt-hour and are expected to keep falling. Bloomberg New Energy Finance projects a further 52% reduction by 2030. Such tumbling prices have led Wood Mackenzie to forecast that as the market for solar plus storage matures, it could put more than 6,400 MW of new natural gas-fired peaking capacity in the US at risk by 2027.

        Amid Global Battery Boom, 2019 Marks New Era for Energy Storage

        By most measures, 2018 was a long-anticipated breakout year for batteries, with record volumes of investment flowing into research, product development and manufacturing as prices plummeted, governments established new policies supporting energy storage, and mass markets emerged for electric vehicles and electrochemical energy storage. That progress, though uneven across U.S. and international markets, sets the stage for a new era for energy storage in 2019 and beyond, industry analysts said.

        Colorado Could Save $2.5B Through 2040 by Replacing Coal with Clean Energy: Report

        A new model of Colorado's energy mix shows consumers could save $250 million annually over a 10-year span if the state were to replace its coal plants with a mix of wind and solar, backed up by energy storage and natural gas. The report, commissioned by clean energy developer Community Energy and completed by Vibrant Clean Energy, also estimates the new resources would cut Colorado's state-wide annual carbon emissions from power generation by almost two-thirds. The analysis concludes its proposed mix of cleaner resources would save Colorado electric customers roughly $2.5 billion in net present value through 2040.

The Kauai Island Utility Cooperative is finishing up commissioning for the Lawa’i Solar and Energy Storage Project, which combines 28 megawatts of solar photovoltaic capacity with a lithium-ion battery capable of storing 100 megawatt-hours. The battery alone holds more energy than all but one other U.S. plant: the 120 megawatt-hour facility AES built in Escondido in 2017. Taken as a whole, Lawa’i’s storage capacity outranks any other operational solar-paired battery system in the world, according to Wood Mackenzie Power and Renewables.

        Study: Batteries are Coming to N.C., but How Many, How Soon Depends on Policy

        Batteries that kick in when the sun sets or the wind dies down — but also don’t break the bank — have long been seen as the holy grail of carbon-free electricity. Now, a new study out of North Carolina State University shows they’re no myth. Analysts say that batteries already make economic sense for certain uses today in North Carolina, and that if trends continue, by 2030, 5 gigawatts of large-scale battery storage will be well worth the investment.

The use of low cost and environmentally-friendly concrete materials enables the system to achieve low cost per kilowatt-hour and high round trip efficiency while delivering a 30-40 year life without any degradation in storage capacity. Energy Vault figures that a properly configured system will be capable of reaching 100 percent of target power levels in 2.9 seconds.

It will charge from the grid in off-peak periods and power the 200-room site for several hours each day. The lithium ion battery will save the hotel £20,000 a year on its energy bill. It is able to power the hotel, including the restaurant, for up to three hours after a two-hour charge. Electricity company E.ON has supplied and installed the technology at the hotel and will be remotely managing the battery's workload and efficiency from its energy management center in Glasgow.

        As Utilities Fight Distributed Generation, Electricity is Getting Less Reliable

        Providing a stable supply of electricity is a core part of the mission of all utilities, and is demanded by the regulators who oversee them. And yet the security of U.S. electricity supply appears to be getting worse. Not only can solar and batteries supply backup power in the event of an outage, but distributed generation has the advantage of being closer to demand, and can improve the reliability of the grid. Microgrids further enhance this advantage, and are being actively investigated as a means to protect critical infrastructure during disasters.

        Sharing Systems Could Help Building Owners Get More from Microgrids

        Shared microgrids can help building owners lower costs and boost resilience, but big questions need to be sorted out first on how the systems operate. While still a fledgling market, shared microgrids — sometimes called multi-user microgrids — are gaining increased attention from researchers and industry players. As with single-user microgrids, the systems combine some type of energy storage and generation with technology that allows them to separate from the larger grid in the event of a power outage or other disruption. In Chicago, a cluster of museums is exploring the case for combining energy systems, but thorny questions remain.
