2020-01 230 (7.4/d) -63 (-2.0/d) 487 (16/d) 20191231T18:17Z to 20200131T18:15Z (31d) Meter readings: electricity generation 63.4kWh, export 13.1kWh, import 180.3kWh (thus net consumption (I+G-E) 230.6kWh, self consumption ((N-I)/N) 22%); gas ~43.7m^3 (so 487kWh @ 11.1kWh/m^3).
Unusually high electricity consumption possibly in part from extra use of dehumidifier in kids' bedrooms (which could really do with their own MHRV).
HDD12=142 vs 218 last January. (Warmest Jan since 2008.)
2020-02 197 (6.8/d) -127 (-4.4/d) 434 (15/d) 20200131T18:15Z to 20200229T18:15Z (29d) Meter readings: electricity generation 129.9kWh, export 49.9kWh, import 120.1kWh (thus net consumption (I+G-E) 197.1kWh, self consumption ((N-I)/N) 39%); gas ~39.1m^3 (so 434kWh @ 11.1kWh/m^3).
High electricity consumption possibly in part from extra use of dehumidifier in kids' bedrooms again.
HDD12=128 vs 132 last February. (Warmest Feb since 2008 barring 2014.)
