About GridStor

Overview

GridStor, headquartered in Portland, Oregon, is a rapidly growing developer, owner, and operator of grid-scale battery energy storage systems (BESS). The company focuses on integrating renewable energy sources to enhance grid reliability and efficiency

Backed by Goldman Sachs Asset Management, GridStor is well-capitalized to pursue its mission of building a more resilient and sustainable energy infrastructure across the United States. In the past year, it expanded aggressively into ERCOT and CAISO regions, including a new 150 MW/300 MWh facility in Texas

To succeed in increasingly volatile electricity markets, GridStor needed a forecasting solution that could keep pace with changing dynamics. With Nixtla, GridStor transformed its ability to make financially sound, data-backed decisions in real time

MARKET VOLATILITY

The Critical Nature of Energy Price Forecasting

In today's renewable-driven power markets, electricity prices are more volatile than ever. With daily price changes up to 20× greater than stock market fluctuations, and intraday price spikes exceeding 1000% volatility, accurately forecasting these dynamics is mission-critical for energy storage operators like GridStor

  • Need to decide when to charge (when power is cheap) and when to discharge (when prices spike)
  • Even a 1% improvement in forecast accuracy can save millions in operational costs
  • Traditional forecasting models struggled with extreme price volatility driven by renewable generation

TimeGPT: Transforming Forecasting Precision

GridStor partnered with Nixtla to leverage TimeGPT, an AI-driven time series forecasting engine. By integrating vast supply-demand data from ERCOT markets and renewable output into TimeGPT's models, GridStor gained the ability to predict price fluctuations with far greater precision and horizon than traditional methods

  • Significantly improved accuracy for month-ahead hourly forecasts—previously a major challenge
  • Enhanced visibility into future prices allows optimal battery charging/discharging scheduling
  • Enabled long-term planning with quarterly and yearly price trends for new project development
