Utility executives may be calling battery energy storage (BES) systems the holy grail of renewables integration and other industry challenges, but here’s an ironic reality: Most organizations keep that holy grail half full or even close to empty. That’s because most organizations target few value streams from battery systems, damaging the profitability of the investment. Learn how storage investments can provide value along a broader continuum of market-based earning (MBE) opportunities. And how BES systems that are controlled using advanced algorithms can balance a variety of factors to deliver the right service at the right time to the benefit of all stakeholders.
North America currently has over 20 GW of installed utility-scale PV generation. With 2016 seeing the largest amount of PV installed to date with over 14 GW brought online. The majority of this installed utility-scale PV base could expand production hours and increase revenues with the addition of energy storage.
With the ability to control generation and load, storage becomes one of the most critical assets in the utility portfolio. The results of incorrectly assembling disparate components from multiple vendors into a single solution could result in potentially dangerous and expensive failures.
The key to ensuring the successful integration of renewable resources may lie in the availability of real-time series data collected from distributed data points. But the huge amount of data collected from these data points operating at the edge of the grid must be processed, and a number of different formats must be smoothly integrated; the lack of data granularity and existing data silos presents additional challenges.
With billions of dollars invested and gigawatts of solar installed every month, savvy investors and owners understand that to maximize financial returns and optimize solar power plant performance, a well-thought-out plan for a complete operations and maintenance (O&M) program must be baked into the economics of any project before the first boots hit the ground. Single-axis trackers (SATs) have become increasingly popular because of the higher energy yield they produce compared to fixed-tilt systems. This white paper discusses and analyzes the factors to consider when evaluating tracker technologies from an O&M perspective.
The question that is asked more and more frequently is at what point does the value proposition, or total installed costs make it wiser to go with central inverters instead of string inverters? With the recent increase in the capacity, efficiencies, and capabilities of string inverters, the range of applications is reaching the utility scale projects.
Federal, regional and state actions in 2016 have pointed to the evolution of demand response beyond the traditional boundaries of wholesale market design. 2016 began with the Supreme Court upholding FERC Order 745, certifying the legality of demand response mechanisms.
The concentration of global solar demand is more pronounced than at any time in the industry's last seven years, such that the top four markets (China, the United States, India and Japan) are expected to account for 73 percent of total installations in 2017.
