Increased Visibility to the Grid is Happening! Read How — Voices of Experience|ADMS

smart_grid1 Consider the Cost of a Power Outage: “The U.S. Energy Information Administration estimates that the $150 billion in annual economic losses because of outages is equivalent to adding 4 cents per kWh of costs to consumers nationwide.” — Annual Energy Outlook 2010, U.S. Department of Energy

February 23, 2015: What is it really like to deploy an advanced distribution management system (ADMS)? In February 2014 the Department of Energy’s Office of Electricity Delivery and Energy Reliability formed the ADMS Working Group to collect the experiences, insights, and lessons learned from utilities implementing ADMS. The discussions from the Working Group are captured in a guide called Voices of Experience|Insights Into Advanced Distribution Management Systems.

Excerpt from the Guide: “Considering that this is an era in which smart phones and Google Maps are ubiquitous, it may come as a surprise that utilities have very little visibility into their distribution systems. Most systems still rely on breakers to disconnect the lines in the event of a fault, customers to call in to report an outage, and line crews to find the effected circuit and restore power. However, this may be changing.

Today, a number of utilities are implementing advanced distribution management systems (ADMS), a software platform that integrates numerous utility systems and provides automated outage restoration and optimization of distribution grid performance. ADMS functions can include automated fault location, isolation, and service restoration (FLISR); conservation voltage reduction; peak demand management; and volt/volt-ampere reactive (volt/VAR) optimization. In effect, an ADMS transitions utilities from paperwork, manual processes, and siloed software systems to systems with real-time and near-real-time data, automated processes, and integrated systems.”

Utilities that have deployed smart grid technologies have learned lessons and gained insights along the way—sometimes the hard way—that can be applied to new projects as well as existing projects that may be expanding or are presenting challenges. The hope is that sharing this information will help other utilities overcome or avoid some of the challenges these first adopters identified and be able to deploy their own ADMS successfully and efficiently.

ADMS Working Group Guide Summary: (Note:This report was prepared for the U.S. Department of Energy by the National Renewable Energy Laboratory under contract No. DE-AC36-08G028308.)

The American Recovery and Reinvestment Act (ARRA) of 2009 spurred investments in smart grid technology and programs at utilities across the country. The Smart Grid Investment Grant program and Smart Grid Demonstration projects that it funded provided unprecedented opportunities to learn from smart grid implementation.

In 2011, the U.S. Department of Energy, Office of Electricity Delivery and Energy Reliability (DOE OE), in partnership with electric utilities that received ARRA funds, convened a series of Regional Smart Grid Peer-to-Peer Workshops. These were designed to bring together utilities to engage in dialogues about the most compelling smart grid topics in each region. The meetings offered a platform for smart grid implementers at all stages of project deployment to share their experiences and learn from each other.

Realizing the benefits of bringing utilities together to share their experiences, in February 2014 DOE OE formed the ADMS Working Group by assembling a leadership team of representatives from the utility industry with the mission to collect the experiences, insights, and lessons learned from implementing these systems. This guide is the result of a one-day meeting held at CenterPoint Energy in Houston, Texas, in May 2014 that was followed by a series of conference calls about specific aspects of ADMS, interviews with individuals leading ADMS projects at their utilities, and a final small group meeting at San Diego Gas & Electric in California in October 2014. The information in this guide came directly from the people in the industry on the leading edge of transforming their distribution systems.

Although the working group included more than 40 people and represented 30 utilities and organizations, the following were key contributors of their experience:

San Diego Gas & Electric (SDG&E)
CenterPoint Energy (CPE)
Austin Energy
Duke Energy
Kansas City Power & Light (KCP&L)
Pacific Gas & Electric (PG&E)

We hope that sharing this information will help other utilities overcome or avoid some of the challenges these first adopters identified and be able to deploy their own ADMS successfully and efficiently.

Rising Plug-in Electric Vehicle Adoption — Impacts on the Grid (Negligible, for Now)

smartgrid.gov December, 2014″ Six utilities that participated in DOE’s cost-shared Smart Grid Investment Grant (SGIG) program deployed in-home and public electric vehicle charging stations and evaluated customer charging behaviors and impacts on the grid. There are relatively few plug-in electric vehicles on the road today, and as a result the six SGIG projects focused on establishing the charging infrastructure with a relatively low number of stations and evaluated a small number of participating vehicles. As expected, project results showed negligible grid impacts from small-scale electric vehicle charging today, but gave utilities important insights into the demand growth and peak-period charging habits they can anticipate if electric vehicle adoption rises as expected over the next decade.

Charging Behaviors: i. The vast majority of in-home charging participants charged their vehicles overnight during off-peak periods. Where offered, time-based rates were successful in encouraging greater off-peak charging. ii. Public charging station usage was low, but primarily took place during business hours and thus increased the overlap with typical peak periods. Plug-in hybrid owners frequently used the (often free) public stations for short charging sessions to “top off their tanks.”

Grid Impacts: iii. The length of charging sessions and the power required varies based on the vehicle model, charger type, and state of battery discharge. iv. The average power demand to charge most vehicles was 3-6 kilowatts, which is roughly equivalent to powering a small, residential air conditioning unit. v. However, depending on the model, the load from one electric vehicle model can be as much as 19 kilowatts, which is more than the load for most large, single-family homes.

Technology Issues: vi. Faster chargers may require more expertise to install in homes and public stations. Installing a 240-volt charging station, which typically charges 3-5 times as fast as a charger using a standard 120-volt outlet, requires a licensed electrician and occasionally service upgrades. vii. Public charging station installation had high costs and required substantial coordination with equipment vendors, installers, and host organizations to address construction, safety, and code requirements. viii. Low usage at public charging stations will require longer capital cost recovery without substantial growth in usage. ix. Some utilities found residential interoperability problems in communication between smart meters and charging stations. SMUD found that the two devices only connected successfully about 50% of the time during load reduction events.

Advanced Metering Infrastructure: ($1,997,812,053 or 43% Federal Share) Advanced metering infrastructure (AMI) is a system of smart meters, two-way communications networks, and data management systems implemented to enable metering and other information exchange between utilities and their customers. In addition, a subset of SGIG projects are conducting statistically rigorous studies of consumer behavior and demand response. These projects include applications of AMI, time-based rate programs, and enabling technologies such as Web portals, in-home displays, and programmable communicating thermostats. They also include the use of randomized and controlled experimental designs with treatment and control groups. This effort presents an opportunity to advance the electric power industry’s understanding of consumer behavior through highly rigorous statistical methods.

How a VFD Pays for Itself

ga powerThis week Stromquist hosted a Drive to Savings Day with Siemens and GA Power to educate our customers on the benefits of Variable Frequency Drives and GA Power’s current rebate programs for VFDs and other HVAC equipment. Most people already know that installing a VFD can save money by cutting back on the energy it takes to run equipment, but not everyone is aware that there are additional savings to reap by taking advantage of GA Power’s rebate opportunity. For any NEW drive installed on existing equipment, GA Power will issue a $50 per HP rebate. So a 20 HP drive will bring a $1000 rebate. Add that to the money saved in energy costs, and the new drive will pay for itself very quickly!

If you are in Georgia and would like to install some new VFDs, call Stromquist at 404-794-3440. We sell great, competitive drives from Honeywell, Johnson Controls and Siemens. We’d be happy to help you put some money back into your budget. Then maybe you can roll those savings into a new chiller that will also qualify for a GA Power rebate.

U.S. Department of Energy Webinar on Smart Grid Data Privacy: A Voluntary Code of Conduct

smartgrid.govControlTrends Community, here it is. Participation is requested (and important)! DOE information release, November 17, 2014: On Wednesday, December 11, 2014 the Energy Department’s Office of Electricity Delivery and Energy Reliability in coordination with the Federal Smart Grid Task Force will conduct a webinar to conclude the development phase of a Voluntary Code of Conduct (VCC) related to privacy of customer energy usage data for utilities and third parties.

Background: Throughout the U.S., intelligence is being added to the grid through the deployment of advanced technologies and grid modernization efforts. This increased intelligence has led to concerns regarding consumer data access and the privacy of consumer energy consumption data. Historically, utilities have taken very seriously the job of protecting customers’ privacy, and privacy and security protections will remain fundamental objectives. However, with the new technologies being deployed today, these fundamental protections warrant new attention. Consumers must feel secure that their data will be protected and treated responsibly. Therefore, it is important that stakeholders on all sides of the privacy debate work together to address concerns and coordinate activities.

The webinar will summarize changes made to the VCC concepts and principles as a result of comments received through the public comment period. In addition, a proposed implementation plan and adoption process will be presented as well as preliminary results from focus groups conducted to gauge consumer sentiment.

Your participation is important! SmartGrid.gov. Please forward this email to your colleagues that may be interested in this initiative or future notices email alerts from SmartGrid.gov.

Building Energy Efficiency Frontiers and Innovation Technologies (BENEFIT) – 2015 Funding Opportunity Announcement

DOE1The Building Technologies Office (BTO)’s Emerging Technologies Program has announced the availability of nearly $8 million under the Building Energy Efficiency Frontiers and Innovations Technologies (BENEFIT) Funding Opportunity Announcement (FOA) DE-FOA-0001166. This FOA combines an early-stage research and development topic (Innovations) with a later-stage research and development topic (Frontiers) that complements the core funding provided to the national labs. The FOA allows all interested parties, including corporations, universities, and non-profits as well as the national labs, to contribute to advancement in two of these core technological areas: non-vapor compression HVAC technologies and advanced vapor compression HVAC technologies. It is anticipated that six awards will be made and range from $500,000 to $1.5 million

Applications for this funding opportunity are open under the following topics:

INNOVATIONS: Non-vapor Compression HVAC Technologies – This topic includes developing approaches and technologies for heating, ventilating, and air conditioning (HVAC) that replace vapor compression technologies, which are currently the dominant HVAC technologies due to their scalability, relatively compact size, high reliability, and other attributes. However, vapor compression technologies make use of conventional refrigerants. This research topic seeks to explore long-term non-vapor compression solutions that result in HVAC equipment that does not use refrigerants. Solutions for both natural gas and for electric HVAC equipment are of interest.

FRONTIERS: Advanced Vapor Compression HVAC Technologies – Regional HVAC solutions offer significant energy saving potential for new construction and the existing building stock. Today’s vapor compression equipment has limited cooling control. This topic seeks to develop equipment optimized for specific environments and that can provide dramatic improvements in energy efficiency with modest increases to equipment costs. Because the building stock increases by only a few percent annually, concepts which are applicable only to new construction will have limited energy savings potential. Therefore, concepts that are applicable to both new construction and retrofits of existing buildings are particularly encouraged.

HOW TO APPLY: This funding opportunity is open to individuals, corporations, universities, non-profits, as well as national labs. The final funding amount is subject to congressional appropriations.
