About Eighty760
An open platform for high-resolution temporal carbon accounting and stochastic power systems modeling.
Missions & Objectives
Our primary objective is to advance the decarbonization of electrical grids through rigorous, transparent, and high-fidelity data analysis. We contend that traditional volumetric matching—annualized renewable energy purchasing—is an insufficient metric that fails to capture the temporal and locational physics of power systems.
True grid decarbonization necessitates 24/7 Carbon-Free Energy (CFE) matching, aligning load consumption with clean generation on an hourly, or sub-hourly, basis.
The "8760" Paradigm
The nomenclature "Eighty760" references the 8,760 hours in a standard calendar year, representing the fundamental temporal unit of modern grid operations.
Contemporary corporate sustainability strategies predominantly rely on unbundled Renewable Energy Certificates (RECs) to claim "100% renewable" status. This retrospective accounting method obfuscates the reality that consumption frequently coincides with carbon-intensive marginal generation during periods of renewable intermittency (e.g., nocturnal hours or wind droughts).
Eighty760 employs granular hourly modeling to expose these "carbon deficits" and algorithmically identifies the optimal portfolio composition—integrating intermittent renewables, baseload generation, and energy storage—to mitigate emissions with verifiable physical simultaneity.
Methodology & Architecture
Stochastic Generation Modeling
Our simulation engine utilizes ERA5 reanalysis data to model variable renewable energy (VRE) production profiles with high meteorological fidelity. This allows for the realistic representation of inter-annual variability and correlation between generation assets and load demand.
Portfolio Optimization
The "Smart Fill" algorithm leverages heuristic optimization techniques to right-size generation capacities and energy storage duration. The objective function minimizes the Levelized Cost of Energy (LCOE) while satisfying constraint targets for Carbon-Free Energy (CFE) scores, accounting for curtailment risks and storage round-trip efficiency.
Techno-Economic Analysis
We integrate historical Locational Marginal Pricing (LMP) from the ERCOT Real-Time Market (2020-2025) to model financial performance. The model captures battery arbitrage revenue, basis risk exposure, and market purchase costs during scarcity intervals, providing a comprehensive view of economic viability.
Backcasting & Stress Testing
Understanding tail risk is critical for grid resilience. Our Weather Performance module backcasts portfolio configurations against extreme historical meteorological events—such as the 2021 Winter Storm Uri and the 2023 Heat Dome—to quantify performance under stress conditions.
Research & Collaboration
Eighty760 operates as an open platform for energy systems research. We invite collaboration from energy analysts, data scientists, and policy researchers to advance the methodology of hourly carbon accounting:
- Scenario Modeling: Utilize the platform to develop and validate decarbonization pathways.
- Algorithmic Enhancement: Contribute to the refinement of our open-source optimization models.
- Data Expansion: Assist in integrating datasets from other ISOs/RTOs beyond ERCOT.
- Policy Advocacy: Leverage granular data to support evidence-based energy policy formulation.
