Pricing design for Iberian retailers

The retailer's tariff design is the single highest-leverage decision the management team makes. Get the pricing formula right, and the product can run for years without major intervention. Get it wrong, and the retailer is losing money on every customer it sells until the product is repriced.

Most retailers under 1 TWh price by benchmarking against the published competitor offers in the segment, adding a margin, and letting the marketing function take it from there. This works in stable price environments. It under-performs in volatile ones.

What a working pricing framework covers

Five product families, each with its own structural considerations.

Variable-rate tariffs. The customer pays a tariff that adjusts periodically (typically quarterly) against an underlying index. Tracker mechanics matter: which index, what lag, what cap and collar. A variable tariff that lags the index by 6 months in a falling market loses to a competitor's faster-tracking tariff; the same lag in a rising market protects margin.

Fixed-term tariffs. The customer pays a flat rate for a defined term (1-3 years typically). The retailer absorbs the wholesale price risk. The pricing has to include an explicit risk premium that compensates the retailer for the hedging cost and the residual exposure.

Indexed tariffs. Increasingly common, especially for SME customers. The tariff is the wholesale clearing price plus a defined margin. The pricing decision is the margin level and the indexation methodology.

Green-tariff offers. Layered on top of any of the above. The retailer commits to backing the supply with GdOs covering the customer's consumption. The pricing has to include the GdO procurement cost plus margin.

Structured products. For corporate customers. Fixed volume bands, indexed pricing within bands, optionality on volume. The pricing is bespoke and benefits from explicit modelling of the underlying optionality.

Sensitivity analysis is non-negotiable

A tariff that is priced against the current view of the forward curve and current view of the customer mix is fragile. A working pricing framework runs the proposed tariff against:

The MEFF forward curve at the current level, plus and minus 20%
The customer mix shifting toward the heavier or lighter end of the consumption distribution
Weather scenarios that materially change the load shape (extreme heat, extreme cold, mild winter)
Regulatory scenarios (changes to the social bond, capacity charges, system charges)

The output is not "the tariff will deliver X% margin". The output is "the tariff will deliver between Y% and Z% margin under the realistic envelope of conditions". The leadership team then makes an explicit decision about which envelope is acceptable.

Where pricing decisions go wrong

Five patterns.

Pricing committee is a rubber stamp. A formal pricing committee exists, meets monthly, approves what the pricing team brings. The committee should be challenging the assumptions, not endorsing them.

The tariff is priced against last quarter's wholesale. The market has moved; the tariff has not. The pricing should be updated on the cadence the market actually moves, not the cadence the operating review allows.

The risk premium is set by tradition. The retailer has historically added 15% to the wholesale forward curve. The historical reason may no longer apply. The risk premium should be derived from current hedging economics, not historical practice.

The cost-to-serve assumption is stale. The cost-to- serve number used in pricing is from two years ago. The actual cost-to-serve has changed (automation has reduced it, regulatory cost has increased it, or both).

The competitor benchmarking is misread. The competitor's published tariff is not necessarily their average customer's actual tariff. Hidden discounts, loyalty pricing and segment-specific offers can move the actual tariff materially below the headline. The retailer that benchmarks against the headline is pricing against a tariff that does not exist.

How this lands in operations

Pricing decisions affect the book for years. The discipline of running them properly pays back disproportionately. A working pricing function looks like:

A documented pricing framework covering the five product families
A monthly pricing review with proper challenge
Sensitivity analysis on every material tariff decision
A pricing-committee discipline that holds the function accountable to the framework
