Intermittent resources monitoring and forecasting technologies have evolved alongside the renewables industry. In the past, these technologies were seen as optional and expensive. But a combination of regulatory changes caused by the surge of solar and wind capacity in several markets and business model innovations that focus on increasing profitability in an otherwise commoditized market are bringing monitoring and forecasting technologies into the spotlight. Today, monitoring is evolving from traditional data logging into sophisticated analytics, including fault detection systems, condition-based monitoring, and energy management tools. Analytics is essential to new business models for behind-the-meter installations that depend on self-consumption of the electricity generated locally. Forecasting technologies were developed to assist the development of new wind and solar by estimating the total expected generation over an asset’s lifetime. Since intermittent generation is now an integral part of the energy mix, ongoing onsite forecasting is not only a necessity to optimize plant operations, but also a contractual requirement of power purchase agreement and feed-in tariff rules. According to Navigant Research, global cumulative revenue for intermittent energy monitoring and forecasting between 2017 and 2026 is expected to reach $26.9 billion. This Navigant Research report analyzes the global market for intermittent renewables monitoring and forecasting technologies. The study provides an analysis of the market issues, including drivers and challenges, related to renewables monitoring and forecasting. Global market forecasts, broken out by region and segment (intermittent resources forecasting analytics and residential and C&I solar monitoring), extend through 2026. The report also examines the key technologies related to intermittent energy monitoring and forecasting, as well as the competitive landscape.
