Public operational evidence

Data
history.

Retained observations of Romania’s electricity system for research use. Each hourly value is an average of every public Transelectrica reading recorded during that local hour — never a selected point or interpolation.

Hourly method

For every interval from 12:00:00 to 12:59:59 Europe/Bucharest, the platform computes the arithmetic mean of stored operational readings. Hours with no stored reading remain absent rather than being filled.

Transelectrica public source

Evidence boundary

Operational observations and OPCOM delivery-day outcomes are retained separately. Empty intervals remain absent; no value is filled, projected or substituted.

Empirical operating profiles

Typical day
from retained evidence.

Each profile groups the selected retained hourly observations by Romania local hour and plots the arithmetic mean. Longer selection windows are more representative; the selected range remains available in the source-linked table below.

Production & solar

Typical production day.

Observed production and solar output by local hour. This is an empirical operating profile, not a forecast.

System balance

Typical flow day.

Positive exchange means net import into Romania; negative exchange means net export. Values are retained system observations.

Daily market summary

Evidence
by local day.

Daily indicators are calculated only from retained public observations. Sample count is shown so incomplete days remain explicit.

Daily observation

System, solar & exchange.

Hover the graph for exact daily arithmetic means. Solar peak is retained in the table because it is a maximum, not an average.

Show daily market-summary table

MW values are arithmetic means of stored readings on each local day. Solar peak is the maximum stored solar observation. Exchange: positive = net import; negative = net export.

Hourly operational register

Observed solar
over time.

Scrollable retained hourly solar profile across the selected interval. Every point is the local-hour arithmetic average of all stored public observations. Hover for the exact value.

Transelectrica operational feed

Observed solar / retained session.

Use horizontal scroll to inspect the longer curve. Missing retained hours are not connected or interpolated.
