Utility DSM planning and cost-effectiveness studies shouldn't take months of manual work. Get transparent, auditable models that regulators trust.
These problems cost utilities millions in delayed program approvals and manual rework every year.
Your Technical Reference Manual is a black box. Values aren't transparent, calculations aren't reproducible, and when regulators ask questions, you're scrambling for answers.
Your Excel models started simple. Now they're a maze of linked tabs, circular references, and formulas nobody remembers writing. One wrong edit breaks everything.
Every time a new technology emerges—heat pumps, smart thermostats, EV chargers—you're manually rebuilding savings calculations from scratch. Again.
For over 30 years, Lumina Decision Systems has helped utilities, state agencies, and organizations like the DOE, California Air Resources Board, and World Bank build transparent, defensible models for complex decisions.
Every calculation visible and traceable
Add new measures in hours, not weeks
Built for regulatory scrutiny
Influence diagrams everyone understands
See how teams like yours transformed their cost-effectiveness workflows.
Our development process iteratively refined each module to find the most appropriate level of detail or aggregation, so we needed the flexibility of changing array dimensions without requiring rewrites of the model structure.
When we decided to expand the scope of our analysis for this project, Analytica's Intelligent Arrays allowed us to make simple changes that propagated throughout the model. The time savings offered by Analytica relative to Excel was tremendous.
The primary advantage Analytica provides over competing tools is its flexibility and responsiveness to client needs, which stem from its Intelligent Array algorithm. This feature lets us adapt quickly to client requests for new scenarios or technologies with minimal effort. It also results in faster, lower-cost development, often by a factor of two or three.
Real outcomes from utilities using Lumina's solutions.
"The way Analytica handles multidimensional arrays is a huge advantage over spreadsheets. The arrays of up to six dimensions would be virtually unmanageable in a spreadsheet, especially for quality control. We are so pleased with Analytica that we're recommending it for several other major projects at Bechtel SAIC."
