At NEI, precision matters.
That’s why we use Energy Toolbase (ETB) — the industry’s most trusted software for modeling solar and battery savings.
ETB allows our team to:
Accurately calculate energy production based on your actual utility data.
Model Time-of-Use (TOU) rates and demand charges from your utility.
Show true financial savings, including federal & state incentives.
Include realistic escalators and tax benefits for full transparency
When we present a proposal, every number has a source. Every projection has a purpose.
Accurate. Transparent. Trusted.
That’s the NEI difference!!
