PRM
Know what your electricity actually costs to supply, before you sign anything.
Know what your electricity actually costs to supply, before you sign anything.
What it is
Feed PRM a year of the site's own 30-minute interval data and a candidate retail offer, and it rebuilds every cost a retailer will actually incur to serve that site over a one- to five-year contract. Stop pricing on averages - price on the site's own half-hours.
The build-up covers wholesale energy priced on the site's actual time-of-use shape under Expected, High and Low price scenarios; capacity cost driven by the site's own behaviour at the published IRCR (Individual Reserve Capacity Requirement) peak intervals; Western Power network charges under every applicable tariff - two-part, three-part and super-off-peak structures, kVA demand charges and metering - with the cheapest tariff for the site's shape named explicitly; market fees and environmental certificate costs; and escalation applied the way retailers actually contract, from quarterly energy movements to contract-anniversary tariff resets.
Three offer structures
- Bundled - Peak/off-peak energy plus a supply charge - the retailer absorbs all cost.
- Bundled with selective pass-through - You choose which cost components the customer carries.
- Unbundled - Energy only - everything else passes through, priced at Southern Terminal or delivered.
It scales to a portfolio, not just one site: hundreds of NMIs (National Metering Identifiers - the connection points a network bills) in a single run, each calculated on its own and then rolled up into a true portfolio aggregate - never a sum of non-coincident maxima.
The calculation reproduces the industry practitioner's own cost-of-supply model exactly, and is checked against it on every change to the platform - so the numbers you see are the numbers a retailer's own analyst would build by hand, not an approximation.
What you get
- Margin by month over the contract term - Year 1 to Year 5 and cumulative, in dollars, percent and cents per kWh
- Security deposits (the market operator and Western Power) and a dated cashflow with GST timing
- Return on capital against a further-discount table - how much margin a deal can give away before it stops paying
- Risk flags: margin at risk under a High price scenario, a price-risk factor, IRCR peak exposure, and T-channel / power-factor discrepancies
- Reference data kept current for you - gazetted retail tariffs, Western Power network tariffs, loss factors chosen by the site's own tariff, voltage and location class, certificate rates, market fees, the capacity price table and public holidays, all effective-dated
- Horizon warnings whenever a quote reaches past the end of the reference tables, so nobody signs off on a placeholder unknowingly
Who it's for
PRM is built for anyone who needs the retailer's side of the table, not just a headline rate:
- Small or new retailers in the WEM (Western Australia's wholesale electricity market) - pricing a C&I (commercial and industrial) customer by rule-of-thumb margin on a spreadsheet nobody fully trusts, where one mispriced site can wipe a year's margin.
- Energy advisers and broker-style consultants - whose clients ask whether an offer is any good, and the honest answer needs a cost stack, not a c/kWh comparison. (Advisory only - see below.)
- Large C&I customers and embedded-network operators - whose capacity and network charges - much of the bill - are driven by when they use power, not how much.
- Retailer risk and finance teams - who need to know what deposits they'll post, what a high-price scenario does to margin, and where the risk actually sits.
- EnergyWholesale, on the site's own time-of-use shape
- CapacityDriven by your behaviour at the IRCR peak intervals
- NetworkCheapest Western Power tariff for your shape
