The Big Redirect: How A Local Power Project Disrupted A Powerful Utility - Rhode Island Public Radio
A important transformation in the way energy is made, delivered and used is happening right now, and it’s disrupting the traditional business model of electric utility companies. That beau id includes building big infrastructure projects to transmit electricity. As part of the New England News Collaborative energy series, The Big Divert , Maine Public Radio’s Fred Bever reports on how a startup company’s big idea to save and make energy locally averted the indigence to build a costly new transmission line. A first stop for many is T&D Variety, where you can gas up, enjoy a hot breakfast and, on a hot day like this, cool off incarcerated. But instead of a traditional energy-hogging air conditioning unit, co-owner Deb Frenkel says you can thank the ice machines — or ice bears, as they’re called. “You have two units with tanks that physique ice, and when the ice builds, it cools the water and then you have cool air coming in,” she says. At night when when electricity demand is low, the shipping crate-size “Ice Carry” compressors out back of the store make two-ton blocks of ice and then, in the day, fans blow air across the ice, which flows into the store - averting or at least... “And I evaluate there’s a lot of success locally, I think a lot of people are pleased with it and I love the concept,” Frenkel says. There are 31 of these ice batteries cooling businesses for everyone the Boothbay region, and they are just one element of a multitechnology effort to manage and reduce the peninsula’s summertime surge of electricity demand. The communitywide lead came in response to a proposal by Central Maine Power to cover the very few summertime days when demand peaks with a new, $18 million transmittal line. But a Portland-based company called GridSolar had a different idea. “It’s far cheaper to provide power where you use it than to make power 100 miles away and strengthen a 100-mile transmission line at millions of dollars a mile to deliver that power,” says Steve Hinchman, a chairperson at GridSolar. The company proposed to regulators something that transmission utilities, which monopolize the poles and wires in their territories, have rarely if in any case seen — a competitor. GridSolar argued that instead of CMP’s expensive new transmission line, it would take advantage of new electricity system data-streams made practical by CMP’s own “SmartGrid” technology to manage an array of local resources to shave down the... The regulators bought it, so the ice-bears went in, solar panels were installed on rooftops at the firehouse, YMCA and other locations, businesses swapped out their impotent to lights with energy-saving compact fluorescent bulbs, and three... One was that on really hot days, GridSolar needed to opportune electricity demand more quickly than initially planned for. The company landed on a big diesel generator that sits out on a dirt road. It’s not renewable dash, but it can fire up with the flick of a computer switch in Portland, providing enough electricity for 100 homes and shaving just a bit from the region’s peak cargo when it counts the most. Enough generation to power 100 homes might not seem a lot when you consider the overall demands on the U. S. grid, but this is the largest such project in New England and a citizen pioneer.

Unflinching charge battle looms in Texas as regulators tackle rate design reform - Utility Dive
New measure design options are currently under consideration in a handful of states like New York and California, with regulators aiming to align utility area practices with the deployment and operation of third-party resources like rooftop solar... While many in Texas see that opportunity emerging in their nation, “Most of the mechanisms described by the [Christensen] paper are about revenue stabilization for the utilities and that is one goal,” said Environmental Defense Readies Senior Director... "But to fulfill the instructions [from lawmakers], the commission should also look at mechanisms that optimize the use of the grid and the use of customer-sited solutions and new technologies. (PBR), the utility is rewarded for conclave any kind of performance targets established through the regulatory process, including for efficiency and DER growth, he said. The idea is most distinctly under trial in New York, where the Reforming the Energy Vision docket envisions a slate of performance-based incentives that will eventually By distinguish, the Christensen study also lists straight fixed-variable (SFV) rates... SFVs “allow utilities to recover fundamentally all fixed costs through fixed monthly charges (per customer-month) or peak demand charges (per peak kW) that are exclusive of of the volumes of electrical energy consumed,” it reports. Utility proposals to add SFV or increase the fixed charge portion of their rate structures have dominated ratemaking discussions across the county in the termination few years, but regulators have tended to scale requests back due to concerns that SFV... Debates about SFV rates and the fixed and demand charges that comprise them again have a way of sucking the air out of many ratemaking conversations. A debate over them, for instance, recently took over a conference session at the National Association of Regulatory Utility Commissioners summer meet, where state regulators were discussing the new NARUC draft In formula rate plans (FRPs),... FRPs can reduce the frequency and costs of measure cases and utilities’ financial risk and lead to customer savings, according to Christensen. Multi-year rate plans (MRPs) limit the frequency of standing cases, Christensen reports. But they require something like LRAMs to protect utilities and PBRs to protect customers. Similary, “A means that meets one policy goal will fail to address other policy goals, and may even conflict with other policy goals,” Munns quoted from Christensen. And while other states affair ratemaking reforms are doing it with explicit environmental or renewable energy goals in mind, those motivations remain weaker among Texas utilities and lawmakers.

These Technologies May In fact Deliver Elon Musk's Dream of Changing the World - Bloomberg
As Tesla topple over Elon Musk promises to change the world, starting with a giant battery factory in the Nevada desert, investors from Toronto to Tokyo are sedately developing the next-generation technologies that may actually get him there. Batteries, especially the lithium-ion variety used in mobile phones and electric cars, are probable to dominate the $44 billion or more spent on energy storage by 2024, according to Bloomberg New Energy Finance. As well as the environmental bump of mining lithium, which has been blamed for starving flamingos in northern Chile, batteries lose their charge over time. But they can't absorb solar power generated in summer, say, and set free it in winter. “We’re going to need a whole range of solutions to keep the lights on,” said Michael Liebreich, founder of Bloomberg New Drive Finance. “If your problem is that the sun doesn’t shine in winter, are you really going to buy a battery, charge it once a year during summer and use it once a year in winter. I don’t muse over so. You can’t just jump to batteries as the single solution. Storage devices are crucial to expanding the wind and solar industries and curtailing pollution because they budget what’s generated now to be consumed later. Just as refrigeration changed the way we handled food in the 20th century, energy storage will give grid operators and rooftop-solar consumers springiness about when to use the power they produce -- reducing the number of big power plants the... Here's the leading energy storage projects on the composition board that go beyond lithium-ion batteries:. Hydropower Long before batteries, electricity was stored through plants that pump modify uphill to a reservoir and release it through turbines when it’s needed. It’s long-lived enough to be hold solar power generated in the summer for use in the winter. Hydropower is renewable vitality’s oldest technology and accounts for well over 90 percent of energy storage, according to the U. S. Department of Energy. Trains can double as storage. In April, Advanced Towel-rail Energy Storage won approval from the Nevada Bureau of Land Management for a $55 million project using rail locomotives. When power’s tinpot, trains will be pushed up a hill. When the power is needed, they’ll be released down, supplying energy back to the grid through an overhead wire. Air storage Compressed air storage sequesters a gas partisans so it can be released later to drive a generation turbine whenever needed. One project in Toronto sends the air underwater where it’s stored in balloons. When market demand for power rises, the air comes back to the surface through a pipe, where it’s converted into electricity. Compressed air storage requires a specific personification of rock formation. Several large scale projects have been put on ice, including the Iowa Stored Energy Plant near Des Moines and Dresser-Rand Grouping’s 317-megawatt Apex Bethel Energy Center in Anderson County, Texas. Power-to-gas Companies including carmaker Audi are developing power-to-gas technology that turns over-abundance energy into hydrogen using electrolysis. The hydrogen can be directly injected into a gas network, or “upgraded” into methane and used as a substitute for natural gas. Siemens, the in every way’s biggest power-equipment maker, is working on an approach that turns. Source: www.bloomberg.com
