As Hurricane Irma receded last September, thousands of Floridians sheltered in 115 well-lit schools, drinking hot coffee and communicating with the world through cell phones charged by solar-plus-storage systems.
Funded by a $9.8 million 2009 Recovery Act grant, the solar-plus-storage systems powered the schools despite the overcast weather, while 6.7 million utility customers had no electricity. Like last year’s hurricanes in Houston, Puerto Rico and the U.S. Virgin Islands, Irma made vivid the value
2017 could go down as the year regulated utilities took the lead in energy storage. Several of the most notable energy storage projects this year were done by or for regulated utilities. And that momentum will likely carry into 2018 as well, Tim Gretjak, an analyst at Lux Research, told Utility Dive.
Properly designed SCADA systems provide total site control to optimize power generation, control voltage, maximize revenue, ensure accurate settlements and satisfy utility compliance requirements. This article looks at the role of SCADA systems in utility-scale PV power plants for compliance, operations management, asset management and revenue optimization. It also covers design and deployment considerations.
Many utilities use Meter Data Analytics (MDA) to better support planning and operations. This article looks at how utilities can use advanced meter intelligence to enhance how they plan and manage infrastructure assets. Trimark is an industry leader in providing meter and energy data services and reporting for a variety of initiative and rebate programs and for a variety of purposes, including billing support, operational performance and analysis and system monitoring.
California’s Rule 21 is leading the way for inverters to help support the grid. The revised rule widens the range of conditions during which inverters may operate and allows inverters to provide seven grid support functions. The old interconnection requirements only allowed inverters to operate within a narrow range of IEE frequency and voltage requirements, underutilizing the capability of inverters.
For the renewable-energy industry, energy storage has typically served as a means to an end: maximize the energy used by the transmission grid to boost a project’s production value and bottom line. A good storage system can help do that by regulating the use of variable resources, such as wind or solar power, ensuring such projects meet grid interconnection requirements. For a wind-farm owner, this means storage can fully capitalize on the wind power generated at a farm, and supply it to the grid as needed to provide a better return on investment. It’s a win-win for the facility owner and a utility.
Five quick questions to see if your system is up to the challenge. Many systems claim to be “SCADA.” To laymen, these systems might all look the same. However, utility-scale PV resources require much more capability and automatic controls than simple data acquisition systems (DAS) that monitor a few points.
This article reviews the role that technology plays in three areas of plant performance, including regulatory compliance, operations management and asset management.
SCADA systems are critically important to the success of large-scale PV production facilities. They enable grid operators to monitor and dispatch power plants in response to constantly changing loads. This article provides a high-level overview of the utility grid with a discussion on how reliability coordinators and balancing authorities work together to maintain power quality and grid reliability. It looks at the challenges that grid operators face and best practices to successfully implement SCADA systems.
Providing stable, reliable power to the grid from a PV system is important, especially where PV penetration is large. Trimark’s supervisory control and data acquisition (SCADA) technology provides grid stability support at two solar PV sites in Fall River, Massachusetts. Borrego Solar, who built the projects which are owned by National Grid, contracted Trimark to help with voltage regulation power factor control.
