Independent Engineering
Advice is shaped around project requirements, not equipment sales.
Independent energy engineering
Energy systems shaped by insight, designed for resilience.
JLJ helps stakeholders, builders, and architects plan resilient energy systems—from battery backup and solar contribution through electrical scope, permitting, and project delivery.
How JLJ works
Integrated Solutions
Electrical, storage, controls, and delivery constraints are considered together.
Safety & Compliance
Code and permitting implications remain visible throughout scoping.
Measurable Impact
Design decisions connect to runtime, resilience, and practical project outcomes.
Consulting scope
Start with the work your project needs.
Core consulting
Consulting
General advisory support by phone, video, or on-site.
Deliverable
Design Package
A technical design package for the proposed system.
Compliance
Fire permitting
Additional professional permitting scope when fire-code review is required.
Philosophy
Resolve the system before selecting the parts.
JLJ keeps requirements, operating conditions, technical scope, compliance, and delivery responsibility connected before equipment decisions become commitments.

Projects
Selected energy systems shaped around operating requirements, site constraints, and coordinated delivery.
Black Mesa
"Black Mesa" is a grid-scale battery energy storage plant organized around modular, independently controllable storage groups. The reference design ranges from 228 to 640 MWh and can operate either as one aggregated grid resource or as separate battery banks when system conditions require isolation.
Meadowline
"Meadowline" is a 2.18 MW DC community solar project interconnected with a regional investor-owned utility and serving residential subscribers across the surrounding service territory.
Ridgeline
"Ridgeline" is a fully off-grid resort development planned to grow from an initial cluster of cabins to several hundred over a multi-decade build-out, with no utility connection at any phase. The project required an electrical architecture that could expand incrementally without reworking the underlying system at each stage.
About JLJ
