Notes on Iberian energy operations
Practitioner notes on the operational realities of running an Iberian retail or trading book against OMIE, MEFF, REE, the DSOs and the regulatory cycle. Written for COOs, Heads of Trading, Heads of Operations and the architects who support them.
These notes sit alongside the energy operations services line. Each piece covers one of the operational realities that turn up in an Iberian retailer or aggregator and the practical approach that works.
The pieces are written from the practitioner side, not the consultancy side. Where a specific market mechanism or regulatory instrument is referenced, the underlying material is linked.

Tailored reporting for Iberian retailers
Beyond the standard analytical output, most retailers have one or two specific reporting needs that do not fit the standard frame. Private-equity covenants, sustainability-linked loan reporting, counterparty credit committees, shareholder packs. A note on how to scope the bespoke work.

Regulatory monitoring for Iberian retailers
The Iberian regulatory environment moves more often than most operators realise. The CNMC issues resolutions that affect billing, the Ministerio adjusts the social bond, the EU directives reshape the wider market and the upcoming Electricity Market Design reforms will land across 2026 and 2027.

Building analytics dashboards for Iberian retailers
Most retailers have a billing engine that produces reports, a CRM that produces reports, a trading desk that produces reports, and a regulatory function that produces reports. None of these report against each other without manual work, which means the management team makes decisions from partial visibility.

Iberian wholesale market reporting
Most Iberian retailers do not have the bandwidth to track the wholesale market with the depth their pricing function actually needs. The reporting that is generally available is either too high-level for pricing decisions or buried inside subscriptions the procurement function does not see.

Pricing design for Iberian retailers
Tariff design is the single highest-leverage decision the retailer makes. Done well it underwrites years of stable margin; done poorly it loses money on every customer for the life of the product. A note on what working pricing design covers.

Submitting regulatory reports in Iberian energy retail
The Iberian retail licence carries a calendar of mandatory submissions to the Ministerio, the CNMC, REE and OMIE. The cadence ranges from daily settlement reports to annual operating returns, and each filing has its own sanction exposure for misses or errors.

Customer service operations in Iberian energy retail
Customer service in an Iberian retailer serves three distinct populations with different complaint patterns, different regulatory obligations and different margins. The operating models that work for one rarely work cleanly for another.

Back-office operations for Iberian retailers
The back office is the part of the retailer that most CEOs do not understand in detail and that determines whether the business is commercially viable. Invoice generation, direct debit collection, dunning, customer data management. A note on what good looks like.

Switching and ATR with the Iberian DSOs
Switching customers in and out of an Iberian retail book runs on the SIPS data exchange with the eight major Spanish DSOs and Portuguese e-Redes. The formats are documented; the operational realities are less so. A note on the patterns that determine whether a retailer's net position grows or quietly leaks.

GdO procurement and registry management
Guarantees of origin are now a material commercial input for any Iberian retailer selling a green-tariff product. The supply is thinner than the demand, the secondary market is fragmented, and the registry operations are easy to get wrong. A practitioner's note on the operational discipline.

Billing management: DSO, REE, OMIE and MEFF
An Iberian retailer receives between five and twelve material invoices a month from the system operators, the DSOs and the market operators. The reconciliation cycle against these invoices is where most retailers find their largest month-on-month variances, and where the operational discipline is most often weak.

Calculating and monitoring trading guarantees
Trading guarantees are one of the largest line items on an Iberian retailer's working-capital position, and one of the most operationally fragile. A note on what a working guarantee monitoring function actually has to cover.

Purchasing in MIBEL intraday markets
The MIBEL intraday markets sit between OMIE day-ahead and the REE balancing platforms. They are how a retailer adjusts a position after the day-ahead clears, and they are where a meaningful share of the operational margin in a retail book is made or lost.

Operating against OMIE: a practitioner's note
OMIE day-ahead is the central settlement layer of the Iberian wholesale market. The market design is well documented; the operational realities of running a book against it are less so. A note on the patterns that matter for a retailer or aggregator.

Demand forecasting in an Iberian retail context
Hourly demand forecasting for an Iberian retail book is a different problem from the forecasting most teams inherit from generation planning. Weather, calendar, tariff shape and CUPS mix interact in ways that simple seasonal models miss, and the cost of being wrong on a single afternoon shows up in margin within 48 hours.
