Best Practices - Energy
Operational guidelines for energy professionals, AI/RAG system developers and consultants working in the Italian and European energy market.
Always cite the source and year for every tariff figure
Every quantitative value (PUN €/MWh, distribution tariff €/kWh, ISEE threshold for social bonus) must be accompanied by the official source (ARERA, GME, MASE, Terna) and the reference year. Tariff values change frequently (quarterly ARERA updates for regulated services, market fluctuations for free contracts). Citing figures without a source risks being misleading or outdated. Source: ARERA, GME.
Verify POD/PDR code validity before any contractual operation
The POD (electricity) or PDR (gas) code must be verified in the Integrated Information System before initiating a switching or transfer procedure. Incorrect codes cause delays or rejection of the process. Source: ARERA - TIMOE.
Distinguish between contracted, available and peak power
Contracted power is what is paid for; available power is contracted plus 10%; peak power is the actual maximum drawn. For industrial sites, monitoring peak power avoids overloads and penalties. Source: ARERA.
Monitor hourly consumption profiles with smart meters
Smart meters 2G transmit hourly consumption profiles. Analysing them enables contract optimisation (switching to two-rate, shifting flexible loads to F3), reducing imbalance and planning Demand Response participation. Source: ARERA, Terna.
Do not confuse energy (kWh) with power (kW)
A common error is treating kWh and kW as interchangeable. Power (kW) is the rate of energy use; energy (kWh) is the quantity consumed. For electricity billing both are relevant: power affects the fixed charge, energy the variable charge. Source: ARERA.
Assess consumption profile before choosing the contract type
Customers with low, uniform consumption benefit from fixed tariffs for budget certainty. Large industrial consumers with load flexibility may benefit from variable or interruptible tariffs. Analysing the historical load profile is the starting point. Source: ARERA.
Document self-consumption measurements for incentive calculations
For prosumers with Net Metering or CER, accurately recording energy produced, self-consumed and fed into the grid is essential to correctly calculate GSE incentives and tariff compensation. Source: GSE.
Respect ARERA switching deadlines
The switching process has strict ARERA-defined deadlines. Suppliers must respect maximum activation timelines; customers must send cancellations (where required) within contractual terms. Violations cause penalties and complaints. Source: ARERA - TIMOE.
Assess the impact of EU ETS on thermal electricity costs
The CO2 carbon price (EUA) in the EU ETS directly affects the production cost of thermal power plants and therefore the wholesale market price. Energy price forecasting models should always include a CO2 price projection. Source: European Commission.
Keep contracts updated when ARERA regulations change
ARERA regularly updates its resolutions (network tariffs, service quality, switching). Supply contracts must be aligned with current regulations. Best practice is to subscribe to official ARERA communications. Source: ARERA.
Separate revenue streams for RES plants (incentive vs. market)
An incentivised RES plant receives both the GSE incentive payment (feed-in tariff or premium) and the market price for energy fed into the grid. Keeping the two components separate in accounting and management systems avoids reporting errors. Source: GSE.
Use aggregated anonymous data for consumption analysis
Analysing final customer consumption profiles requires GDPR compliance. Prefer aggregated and anonymised data for energy analyses, retaining individual data only for strictly necessary contractual purposes. Source: GDPR (EU Reg. 679/2016), ARERA.
