Energy Recommendation System

My Role & Impact

I led the design and implementation of an intelligent energy recommendation system that prevents grid blackouts by coordinating energy usage across thousands of commercial buildings. As technical lead, I architected a production‑ready solution that achieves 5.4% grid demand reduction, representing $2–5M annual value for metropolitan utilities facing extreme weather challenges.

Key Leadership Decisions

• Designed three‑stage ML pipeline balancing accuracy with operational constraints
• Chose multi‑output LSTM architecture enabling cohort‑specific forecasting at scale
• Established realistic compliance modeling (36.3% rate) based on industry research
• Coordinated cross‑functional team development with clear interfaces and parallel workflows

The Business Challenge I Addressed

Power grids across the US face increasing instability as demand patterns become unpredictable during extreme weather events. When thousands of buildings simultaneously spike energy consumption during heat waves or cold snaps, the result can be catastrophic grid failures and costly blackouts.

The Strategic Opportunity: Demand response programs can reduce 6+ megawatts during peak periods—enough to power 1,500 homes—but existing solutions rely on generic, uncoordinated recommendations. I identified the core technical gap: no system could learn from building‑specific behavior patterns and optimize recommendations at the portfolio level.

Market Context: The demand response market is expanding at 14.3% CAGR toward $3.6B by 2034, driven by utility needs for real‑time grid management and automated demand coordination.

My Technical Approach & Architecture Decisions

Decision 1: Multi‑Stage Pipeline Architecture

Rather than attempting end‑to‑end deep learning, I chose a modular three‑stage approach:

• Stage 1: Multi‑Cohort Forecasting – LSTM neural network predicting 24‑hour demand for 15 building types
• Stage 2: Compliance Prediction – Realistic modeling of which buildings will actually follow recommendations
• Stage 3: Portfolio Optimization – Coordinated selection maximizing grid impact across building portfolio

Why This Architecture: Enables parallel development, allows individual stage optimization, and provides interpretable decision points for utility operators.

Decision 2: Production‑First Performance Requirements

• <30 seconds end‑to‑end processing for 8,000+ buildings
• <50MB memory usage for cost‑effective cloud deployment
• Real‑time inference capability for operational grid management

Implementation Strategy: PyTorch‑based LSTM with distributed computing architecture, avoiding complex ensemble methods that would compromise latency requirements.

Decision 3: Realistic vs. Theoretical Optimization

• Modeled 36.3% average compliance rate based on industry research
• Designed for 5.4% grid reduction (within 2–7% commercial demand response benchmarks)
• Created multiple scenario planning (conservative 30%, emergency 70% participation)

Strategic Rationale: Utility operators need reliable, predictable results for critical infrastructure decisions rather than optimistic projections.

Key Technical Innovations I Implemented

Multi‑Output LSTM Architecture

• 15 building cohort‑specific prediction heads covering >94% of commercial building stock
• 48‑hour weather lookback window capturing thermal lag effects
• Temporal validation splits preventing data leakage

Performance Achievement: 12.4% MAPE under normal conditions, 23–28% MAPE during extreme weather—within production‑viable range.

Portfolio Coordination Algorithm

• Constraint‑based optimization respecting building limitations
• Grid strain detection identifying critical intervention periods
• Coordinated response planning across diverse building types and sizes

Business Impact: Achieved 5.4% aggregate reduction through coordinated recommendations vs. 2–3% typical for uncoordinated approaches.
