Anchor Power Solutions created EnCompass software to help power companies make optimal power supply decisions in the transitioning market. The software comprehensively evaluates new technologies for decarbonization and sustainability. EnCompass is an elegant and powerful simulation model that provides a robust user experience. EnCompass is flexible, easy-to-use software for all facets of power planning and forecasting. The agile system has extensive capabilities to develop power supply plans, determine the economic value of power projects, and evaluate the impact of market, environmental, and regulatory changes. EnCompass is the only model needed for all facets of power planning and forecasting. It combines power plants and complex contracts’ full operational detail with the ability to simplify and relax constraints for long-term simulations. Traditional long-term planning models are often overly simplistic and ignore ancillary services, ramp rates and startup costs. Most short-term models are data-intensive making it difficult to manage scenarios and uncertainties around prices, demand, and availability. EnCompass overcomes these drawbacks by combining an extensible Time Series data model with performance options for managing runtime and complexity, while always maintaining chronological constraints. EnCompass makes it possible to analyze and defend data from one cohesive system. Perform a full optimization of all resources within a market or utility control center enforcing transmission limits and a complete set of operating costs and real world constraints. Build better models and evaluate new technologies for sustainability.
