Utility Scale Central Inverters: Features That Matter and Best Practices

The solar industry is evolving constantly, with an increasing number of strict requirements and standards being imposed on PV plants for 2018 and beyond. Some new standards, for instance, require the inverter either to have a wide range ride through capability or to provide special grid support functions, many of which have been hard to meet for some manufacturers. Sungrow, in response to new standards for 2017, released its grid support utility-interactive inverter, the SG2500U, for the next generation of utility scale PV plants. The SG2500U is the world’s first UL1741-SA certified utility-scale solar central inverter that is compliant with the latest standards required for North America.

The Evolution of The California Energy Market

California always seems to be at the center of innovation. When it comes to sustainable and renewable energy goals, it continues to deliver by leading the evolution of our nation’s energy mix away from finite sources that dominated the 20th century to the renewables that are poised to fuel our world today and in the future. Achieving the state’s ambitious renewable energy goals, however, involves changing the way California procures, distributes, and uses energy.

4 Key Steps to Prove Bottom Line Impact of Efficiency & Sustainability

Most energy efficiency programs can pay for themselves in just one year. It’s not uncommon for large multi-national companies to sustain a five percent energy reduction year-over-year to realize 30 percent or more in reduction over time. That’s just the beginning of the potential energy efficiency savings many companies are missing out on simply because they don’t have a shared corporate vision, a clear financial plan or a way to track and verify results.

Launching a successful efficiency program starts with building an effective business case that not only sells the plan internally, but also helps to ensure momentum throughout implementation.  Drawing from real-life experience, our clients and energy experts have identified these key steps to creating an effective business case for efficiency.

The Digital Grid: Building the Foundation With IoT and Data Analytics

Conditions are changing faster than ever in electricity distribution markets throughout the U.S. Utilities are facing increasing pressure to maintain reliability, improve resiliency, integrate renewable generation, enhance customer options and services, and ensure sound financial performance—all at the same time.

PJM Capacity Performance Is Here. Don’t Believe The Myths.

This past May, PJM ushered in a new era for Demand Response (DR) with the DY 2020/21 Base Residual Auction (BRA). The legacy summer DR programs of the past, such as the popular Limited and Summer Extended programs, will soon be gone. In the foreseeable future, Capacity Performance will be PJM’s only game in town for forward capacity Demand Response.

Making Utility-Integrated Energy Storage A Used, Useful & Universal Resource

Objective signs are everywhere that the stationary energy storage market is growing up quickly. The use of distributed resources such as solar photovoltaics and electric vehicles are expanding at a rapid pace, creating technical challenges for the distribution system that will require energy storage and a new generation of software to address.
