Solar tariffs and regulations in Spain
Compensación simplificada, the 2.0TD and 3.0TD access tariffs and the power terms behind them. Spain settles surplus month by month, and whatever is not used inside that month is lost.
Every market, every tariff, built in
Net metering, net billing, credit carry-over, feed-in tariffs and hourly or monthly netting all live in the tariff configurator, alongside time-of-use, tiered and demand charge structures. Tune currency, seasons, export rates and VAT, or build a brand-new tariff structure when a market changes the rules.

Compensación simplificada
Under RD 244/2019, plants up to 100 kW have the value of their exports deducted by the retailer from the energy term of the same month's bill. It is a monthly settlement, not a credit balance that accumulates over a year.
The deduction has a ceiling and no carry-over
Compensation cannot exceed the energy cost of the month, cannot touch the power terms or taxes, and unused surplus is simply lost. Oversizing beyond what the site consumes in a given month returns nothing, which makes monthly load shape the sizing constraint.
2.0TD, 3.0TD and the high voltage tariffs
Residential 2.0TD has three energy periods, punta from 10:00 to 14:00 and 18:00 to 22:00, llano at the shoulders and valle overnight, plus two power periods. Above 15 kW, 3.0TD runs six periods, and 6.1TD to 6.4TD apply by voltage level. Each carries power terms per period.
Fixed price or PVPC changes the export value
Fixed-price offers typically pay between 0.05 and 0.12 euro per kWh for surplus. PVPC pays the hourly market price, which is often near zero in the middle of the day, exactly when a rooftop exports most. Retailer virtual batteries bank the value that would otherwise be lost.
01What happens to surplus not used within the month?+
It is lost. Compensación simplificada reconciles month by month with no carry-over, so a system that produces far more than the site consumes in a low-demand month gets nothing back for the difference. Annual production is the wrong number to size against in Spain.
02Can the compensation reduce the power term?+
No. The deduction applies only to the energy term of the bill. Power terms, taxes and other charges stay payable in full, so a proposal that nets a Spanish bill down to zero is not describing what the customer will receive.
03Do virtual batteries change the model?+
They change where unused surplus goes. Several retailers bank value beyond the month and release it later, but the terms are commercial and specific to each offer, so they belong in the model as the retailer's actual conditions rather than as a regulated mechanism.
04Which Spanish tariffs are preloaded?+
Twelve, covering the regulated access tariffs 2.0TD, 3.0TD and 6.1TD to 6.4TD along with Endesa retail products including the Nocturna, Tempo 24H and Tempo Solar structures. Periods, power terms and export prices stay editable per project.
