nEP, the nu-Energy Platform

Most commercial energy proposals are built in a spreadsheet, from a rule of thumb and a roof area. Ours are not.

nEP is the nu-Energy Platform, and it is entirely our own. We designed and built every part of it in house, and nu-tility owns it outright. It is not a licensed package, not a reseller portal, and not an industry tool our competitors also run. It is proprietary, and it is why our numbers look different to everyone else’s.
nEP takes your real metered interval data and your actual network tariff, models generation and consumption across the year, and sizes the system to the strongest financial outcome for your site. Here is what it does differently.

It sizes to economics, not to area.

The recommendation is the largest system that still clears a hard return threshold, tested against your load, not the largest system the roof will hold.

It values exported energy at zero.

Every number in your proposal stands up whether or not your network approves export. Anything you earn from export is upside we have not counted.

It models your tariff, not an average price.

Commercial energy is not one number. You pay different rates at different times of day, and on most network tariffs a large part of your bill is a demand charge set by a single half hour peak across the month. nEP models the whole structure, peak, shoulder, off peak and demand, at half hourly resolution against your own consumption, because what you save depends on when the system delivers, not only on how much it generates.

It tests batteries honestly.

We assess battery storage on lifecycle net present value across all its value streams. If the numbers do not clear the threshold on your site, nEP says so, and we recommend solar alone. We would rather decline a battery than sell you one that does not pay.

It co-optimises the battery across every stream at once.

A commercial battery earns in three ways. It lifts the share of your own solar you use rather than export. It arbitrages time of use tariffs, storing cheap energy and discharging it into peak periods. And it shaves the demand peak that sets your demand charge. Those three compete for the same capacity and the same power rating, so nEP dispatches across all of them together rather than optimising one and hoping the rest follow. It also tells you which stream actually pays on your tariff. On some networks time of use arbitrage is worth very little, and it is better you know that than be sold on it.

It models the whole life, not the first year.

Every proposal carries a full twenty five year cashflow. Panel output declines each year, battery capacity fades with use, and inverters and battery cabinets reach the end of their service life and are replaced. All of it is in the model, with its cost, in the year it falls. Most proposals show a first year saving and a simple payback and stop there, which quietly leaves out every cost that arrives after year one.

It discounts properly.

We calculate net present value and internal rate of return across the full term, alongside payback. Payback on its own flatters a system, because it stops counting on the day the system pays for itself and ignores the twenty years after that. For an asset with this life, that is most of the story.

It shows you the counterfactual.

Alongside what you pay with the system, nEP models what you would have paid without it, year by year across the term, on a grid price escalation we keep deliberately conservative. Your saving is the gap between two modelled futures, not a percentage applied to last year’s bill. We write down every assumption behind that gap in the proposal, so you can argue with it.

It prices from real costs.

We cost every line, hardware, electrical, structural engineering, compliance, monitoring and access equipment, from current supplier and subcontractor pricing on your specific site. Nothing is a percentage of something else.

It handles both structures.

nEP prices an outright purchase and a power purchase agreement on the same basis, so you compare two properly modelled options rather than a quote against an estimate.

It prices a power purchase agreement properly.

Under a PPA you put in no capital. nu-tility funds, owns, operates and maintains the system, and you pay only for the energy it produces, at a rate below what you pay the grid today. nEP solves that rate against the actual cost of delivering your site across the full term, so the number you are quoted is derived, not marked up from a competitor’s.

It prices portfolios, not just sites.

If you run several sites, we model them together as a portfolio rather than quoting one at a time. Each site is still modelled individually on its own load, tariff and roof, then blended into a single weighted average rate across the portfolio, weighted by the energy each site actually produces rather than struck as a flat average of site rates. That matters, because a site that is marginal on its own can be carried inside a portfolio, and one weighted rate across a portfolio is almost always better than the sum of separate deals.

It looks past the bill.

Where a battery is part of the system, the value is not only the energy it shifts. Correctly specified and configured, a commercial battery can be enrolled in frequency control ancillary services and virtual power plant programs, earning revenue from the market for supporting the grid. We size and configure for that from the outset rather than retrofitting it later.
