ENERGY STORAGE SOLUTIONS

Mitigating interconnection & regulatory risk is what we do.

As an Investor or IPP, your key concerns are site risk, interconnection delays, cost overruns, regulatory uncertainty, and ensuring your investments hit targets (both timelines and returns). You need to know which projects are likely to succeed, which are risky, and where to deploy capital efficiently.

We provide you with consulting services and tools for all aspects of energy storage that help you screen opportunities, de‐risk your pipelines, and make smarter investment decisions.

Consulting Services for Energy Storage

Siting & Sizing

Shortlist POIs and right-size campus capacity from Day One.

Shadow System Impact Studies

Mirror TO/ISO assumptions early to avoid surprises.

Electrical Studies

Load flow, short circuit, grounding, harmonics, TRV/TOV, Volt/Var, CYMCAP.

Technical Due Diligence

Risk register, mitigations, and critical-path planning.

Interconnection Application Support

Queue strategy through energization.

Reliability & Economic Transmission Planning

De-risk long-lead items and capital commitments.

Software Services for Energy Storage

REST® Map-Based Screening Across all iso/rto

Use REST to monitor congestion and queue dynamics across regions to shape pipeline strategy.

Sitra™ ERCOT

ERCOT pre-investment checks-Run site-level feasibility to validate assumptions before committing capital.

Explore Sitra™

Our approach to solving key challenges in energy storage.

Interconnection cost & timeline risk eroding IRR We estimate upgrade exposure and schedule risk early with engineering consulting and scenario tools (REST® + Sitra™) so you can stress-test IRR.

Costs • Schedule

Portfolio risk: many candidates, few reliable winners Our experts evaluate sites by grid capacity, congestion, and constraints; to validate shortlists and right-size capital deployment.

Screen • Rank

Regulatory, permitting, environmental uncertainty Consulting maps policy and permit pathways; tools overlay environmental and land-use constraints for early red-flag visibility.

Policy • Permitting

Transmission constraints & bottlenecks that erode value We model flows and contingencies to reveal bottlenecks; our engineers outline mitigation, alternate POIs, and queue strategies.

Capacity • Flows

Policy/market/ISO rule changes Horizon scanning + scenarios testing quantify impacts to revenue and cost

Scenarios • IRR

We'll help you find your ideal build site. Engage us for full siting and energy storage consulting, or use REST® + Sitra™ to accelerate part of the process.
