      IREC Insight Series: Key Lessons from the California Integrated Capacity Analysis

      After 11 months and nearly 20 meetings, a new regulatory working group report is born.  And this one is special. For those who have been involved in or following California’s nearly two-year Distributed Resources Plan (DRP) proceeding (which is a scaled-back west coast version of the New York Reforming the Energy Vision effort), this report represents an important milestone not only in the proceeding, but also for an issue near and dear to IREC’s heart: “hosting capacity” analyses.

    2. Li-ion Energy Storage Takes Microgrids to the Next Level

      Li-ion Energy Storage Takes Microgrids to the Next Level

      Saft explains how microgrids that combine diesel generators, renewable energy resources and lithium-ion (Li-ion) energy storage can enhance security of supply while reducing fuel costs and greenhouse gas emissions. When an energy storage system (ESS) is added, an operator can maximize the contribution of renewables, increasing the penetration of PV power and allowing diesel-off operation. It is possible to realize fuel savings of 50 to 75 percent. Li-ion battery systems have emerged as the technology of choice for energy storage. This is due to their high energy density that enables significant levels of storage capacity to be packed into a relatively compact footprint. Li-ion ESSs are now able to store energy at the megawatt scale, and integrated containerized systems can be connected in parallel to deliver multiple megawatt-hour storage capacity.

      In Virginia Push for Pumped Storage Hydro, Questions Arise About Viability

      In a bid to boost the economy in Virginia’s coalfield region, legislation to be signed by Gov. Terry McAuliffe seeks to spur the development of pumped storage hydro electric power plants using water from abandoned coal mines. While the companion bills in both the Senate and House of Delegates drew virtually unanimous support from both chambers, researchers, coal reclamation experts and even some renewable energy advocates say the idea is still unproven. While pumped storage facilities exist in Virginia and elsewhere, no plant drawing water from abandoned coal mines has been built anywhere in the world.

      More Than 3 Million in US Now Work in Clean Energy

       On Wednesday, February 22, national business groups representing the range and breadth of clean energy companies in the United States cheered government statistics showing their industries support more than 3 million American jobs – equal to the employment of retail stores across the country, and twice as many jobs as involved in construction of buildings. This is based on 2016 data recently released by the U.S. Department of Energy (DOE) in its second annual U.S. Energy and Employment Report. DOE does not offer a definition of "clean energy," and the trade associations representing different portions of the industry have their own ways of defining what "clean energy" represents. But the groups all agree that, in the aggregate, these jobs add up to more than 3 million nationwide.

      Testing for the demonstration of a first-of-its-kind energy storage collaborative project in Hawai‘i now is complete. The customer-sited storage fleet provides 1 MW of storage services across 29 customer sites to accommodate renewable energy resources on the O‘ahu grid. Stem Inc. provided software-driven storage for the project to act as a virtual power plant. A spokesperson for Stem told Renewable Energy World that the 1-MW resource has up to one hour response to Hawaiian Electric Company (HECO) and up to two hours of capacity on a per-site basis, ensuring there is more than enough energy to serve both the customer and the grid.

      Energy Storage for Public Health: A Smarter Way to Deploy Resources

      Energy storage deployment has been ramping up at a rapid pace across the country, mainly because it can reduce electric bills and cut utility expenses. It is now time to consider another key benefit of storage—public health, especially the power of energy storage to reduce pollution in marginalized communities. Researchers at the University of California Berkeley and PSE Health Energy, an energy research and policy institute, recently published an interesting article in the journal Energy Policy on the role of clean energy technologies and public health. It describes a new approach to the siting and dispatch of emerging clean energy resources, specifically energy storage and demand response. The authors argue that policy-driven clean energy deployment strategies should be locationally optimized—policymakers should think more about where these resources should go—based on impacts to air pollution, human health, and environmental justice.

      In Visayas, one of the three main island groups in The Philippines, too much solar on the grid may lead to blackouts during the election period, which begins today, March 28, and lasts until May 7. Grid operators are concerned that too much power is being fed into the grid when all of the solar PV plants in the region are churning out electric power along with the geothermal and coal plants in the region — even if the geothermal and coal plants are dialed down to their minimum load requirements.  Further the swings in power supply due to intermittent PV generation (from 20 to 50 percent) have already caused grid interruptions.

      How Hawaii Has Empowered Energy Storage and Forever Changed the U.S. Solar Industry

      Over the past two years, Hawaii has been ground zero of a historic battle between solar and utilities. With solar penetration at a level unseen in the rest of the country – an estimated 12 percent of all homes – Hawaiian utilities are facing unprecedented challenges in figuring out how to integrate such a large quantity of renewables into their existing electricity grid, and how to get customers to pay for it. Given residential solar’s exponential growth across the U.S., the new technologies, business models and regulations that emerge from Hawaii’s experience are seen by many as a preview of what’s to come elsewhere.

      Energy Storage Is a Key Ingredient for All Microgrids

      Recently I read where microgrids that generate half their power from solar supposedly don’t need energy storage. It might be true that they don’t need energy storage, but any microgrid developer that fails to include it in a photovoltaic (PV) project will miss out on a wide range of significant functional benefits that would help make the project successful. As its basic core benefit, energy storage enables microgrids to operate using a non-carbon-emitting resource that allows distributed generation to synchronize with or without the presence of the grid. When PV generation is included within a microgrid, it requires what’s called a voltage source with which to synchronize.
