CalibSun is presenting a scientific poster and conference talk at the 54th IEEE Photovoltaic Specialists Conference (PVSC) in New Orleans this week ! Our team of #data scientists and #meteorology experts is proud to share two major scientific contributions presented by Thomas Carrière and Alexandre Boilley. We are tackling a crucial question that is often overlooked in scientific literature: What happens to solar forecast performance when data actually arrives late in real-time operations? 🔍 The Problem: The "Operational Lag" Gap Most academic backtests assume "Standard" evaluation conditions (where all input data is instantly available). But in real-world "Live" conditions, data lags are inevitable: - Numerical Weather Predictions (NWP) can lag by up to 6 hours. - Satellite imagery often faces delays of several minutes. Ignoring these lags leads to over-optimistic backtests. Our Two Contributions: 📄 The Poster (Scientific Session): We analyze how these real-time data delays affect PV forecasting and demonstrate why backtests must faithfully reproduce operational lags to remain meaningful and bankable. 🗨️ The Conference Talk: We dive much deeper to formalize standard vs. live evaluation protocols. We demonstrate how input lags degrade traditional benchmark models, and showcase the advanced lag-mitigation strategies powering CalibSun’s NEXT forecasting algorithm. At CalibSun, to maintain close-to-ideal performance even during data delays or partial source failures, our NEXT algorithm utilizes robust, state-of-the-art mitigation techniques, including Smart Blending of data inputs (including real-time, on-site data), an Analog Ensemble approach to handle missing context and fail-safe data handling. Therefore, we ensures continuous, high-accuracy forecasting under any conditions. 👋 Want to know more?

Weather #forecasts are something we all rely on daily. ☀️ 🌧️ But behind them lies an invisible infrastructure of millions of data points, complex equations, and some of the world’s most powerful supercomputers. From global models like GFS to regional simulations such as WRF, Numerical Weather Prediction (#NWP) is a constant balance between physics, data assimilation, and computational power. In this article, our expert team breaks down: – how NWP models are built – why they require massive computing power – where uncertainties come from – and how they are used for #energy applications Take a closer look at the hidden machinery behind your forecasts 👇 By Alexandre Boilley, Lead Meteorological Analyst at CalibSun.

☀️ CalibSun has been chosen by GridBeyond as its solar #forecasting provider for intraday trading on a 48 MWp photovoltaic plant in England.   As electricity markets become more complex with higher renewable penetration, intraday bidding and #trading decisions require the most accurate solar and power forecasts. Solar power output prediction combined with pricing forecasts enable maximum return on PV assets while contributing to grid reliability.    GridBeyond chose #NEXT, CalibSun’s solar forecasting service enhanced with on-site data and AI-driven models, as a tool to help GridBeyond optimize its intraday market positioning and maximize its revenues from the #PV plant.   This collaboration reflects a shared commitment to state-of-the-art innovation and technology, as well as a market-driven approach to accelerating the #energy transition. 🤝

From next month, the Deviation Settlement Mechanism (DSM) for solar producers in India becomes significantly stricter under the framework of the Central Electricity Regulatory Commission (CERC)⚡ The deviation band tightens from ±10% to ±5%, and penalties will now apply from 5% deviation. In parallel, the penalties calculation evolves: they are no longer assessed on total installed capacity, but increasingly weighted on the actual available capacity injected. ▪️ This structural shift makes the financial impact more severe and non-linear. ▪️The same forecast error will generate higher penalties. Generic forecasting is no longer sufficient. Solar asset operators must move toward site-specific forecasting that leverages on-site measurements as a core input. At CalibSun, our forecasting architecture is built around in-situ data combined with advanced models to reduce deviation risk and contain penalty exposure.
