Energy Storage and Grid Management

Ensuring Reliability and Flexibility in the Evolving Power Landscape

As the energy transition accelerates, energy storage has emerged as a critical element for managing grid variability, integrating renewables, and enhancing system resilience. From battery systems and hybrid microgrids to large-scale pumped hydro, EPS delivers the technical, financial, and regulatory insight to help clients navigate the complexities of energy storage and modern grid operations.

Industry Challenges and EPS Solutions

Energy storage and grid management hinge on multifaceted challenges spanning design, regulation, and economics:

Technology Selection and System Design

Evaluating different storage mediums—battery (Li-ion, flow, sodium-based), pumped hydro, or emerging alternatives—requires deep technical expertise to identify optimal solutions aligning with site constraints, cost profiles, and operational goals.

Integration with Renewables and Distributed Generation

Coupling storage with intermittent resources like solar or wind demands sophisticated algorithms to handle variability, dispatch schedules, and peak-load management. EPS ensures seamless synergy between multiple generation assets and the grid.

Regulatory Compliance and Market Participation

Energy storage systems must often meet Federal Energy Regulatory Commission (FERC) guidelines, as well as the varied rules set by Regional Transmission Organizations (RTOs) and Independent System Operators (ISOs). EPS guides clients through these regulations, from interconnection standards to market bidding structures.

System Reliability and Grid Resilience

Maintaining frequency, voltage support, and blackstart capabilities under dynamic load conditions can be essential to achieving grid stability. EPS's engineering analyses address potential failure modes and develop strategies for robust resiliency.

Financial Appraisal and Valuation

Energy storage assets involve significant capital expenditures and complex cost-benefit analysis. Accurate valuations must account for incentives, usage profiles, and potential revenue streams—from ancillary services to arbitrage opportunities.

Our Services

  • Conducting techno-economic reviews of potential storage projects, including capacity sizing, equipment specifications, and interconnection feasibility.

  • Designing storage technologies to work in concert with existing or planned generation assets, substation infrastructure, and control systems.

  • Delivering in-depth market analysis and forward-looking projections for storage economics, factoring in energy pricing, ancillary service revenues, and applicable tax incentives.

  • Investigating storage system failures, performance shortfalls, or safety incidents to mitigate recurrence risks and support insurance claims or legal proceedings.

  • Navigating interconnection applications, permitting, and operational compliance with FERC, RTOs/ISOs, and local entities for seamless market participation.

  • Providing rigorous technical and financial testimony where legal disputes arise concerning storage performance, warranty claims, or contractual obligations.

  • Evaluating storage assets in portfolios, mergers, or acquisitions to reveal hidden liabilities, confirm asset integrity, and steer informed investment decisions.
