Online-measurement of the mains frequency. Swissgrid - frequency. The standard frequency in Europe’s electricity grid is 50 Hz.
In North America and parts of Japan, on the other hand, a standard frequency of 60 Hz is used. These frequencies must be kept as stable as possible for various reasons: Time measurement: there are still many clocks which go by the frequency in the electricity grid. If the frequency is higher, they go faster. If the frequency is lower, they go more slowly.Machines: large electrical machines can suffer damage if the frequency is too low or too high, or if it changes rapidly. To ensure the frequency always remains at a stable level the balance between production and consumption of electrical power must always be right.
If the consumption of electrical power is lower than production, the frequency is higher; if consumption is higher than production, the frequency is lower.

Demand: This is the total demand of the entire country (excluding exports) less any unmetered generating sources like wind and domestic solar installations.
France's total demand reflects not only its domestic demand but also its place as a major supplier of base-load and renewable balancing power to Western Europe. Demand 50.71GW Nuclear: Frances primary electicity generating technology. Surplus is exported across Europe. Variations in output are either signs that reactors have been deliberately throttled to match lower demand, or that refuelling or maintenance is ongoing. Nuclear 37.21GW(73.38%) Hydroelectric power: France has a significant number of hydro-electric stations (mainly in the Alpine foothills) which are used to deliver a considerable amount of electricity, and also balance the grid against fluctuations in European renewable sources Hydro 4.90GW(9.66%) Gas: France has little reliance on gas but it has a few gas power stations that run as base load in winter.

Metrics for Data Center Energy Efficiency. By now you’re likely familiar with PUE, or Power Usage Effectiveness, an industry standard measurement for the energy efficiency of a data center.
Despite some claims that PUE is easily manipulated or not enough to judge full environmental impact, many data centers (including Green House Data) are using PUE to measure efficiency. The Green Grid, a consortium of technology companies who aim to improve data center efficiency, has collaborated with industry groups around the world to develop several new metrics to measure carbon emissions and energy use in the data center, including GEC, ERF, CUE, and DCeP. What are these new measurements, and how does Green House Data stack up? First, a quick overview of how the standards were developed. The Green Grid is a nonprofit organization founded in 2006, consisting of technology industry leaders including AMD, Dell, EMC, Microsoft, and IBM. Power Usage Effectiveness (PUE) The classic.
