Adjustable lanyard for work positioning
e GRILLON adjustable lanyard is an easily adjustable work- positioning lanyard that can be used as a complement to a fall- arrest system or to position around a workstation. Its length can be very precisely adjusted for comfortable positioning in single or double mode. It is available in several options and lengths depending on need, and is ANSI compliant.

contributed to changing performance on a month-by-month basis, and to re ne their nancial forecasting accordingly.
Typically, pre-construction estimates of wind speeds and actual energy production gures are used to forecast
a site or portfolio's energy production (the energy budget). Deviations in actual performance from the energy budget are easy enough to track, but, all too often, under- or overperformance is attributed to weather variation.
Abnormal wind speeds are
regularly cited as a leading cause of underperformance in wind energy operators' nancial reports, but
more needs to be done to isolate and accurately quantify their e ects. In doing so, we can more clearly understand whether other factors are at play, and help reduce nancial uncertainty.
e rst step to achieving this is
to analyze how more recent weather anomalies – such as those seen in the USA, Europe, and India - have impacted projects on a portfolio-wide and project- by-project basis. Looking back in greater detail at what happened to the on-
site resource during a given period of underperformance is fully achievable
– and helps operators gain an overview of just how much resource uctuations really made a di erence.
In turn, project operators will bene t from greater exibility and increased accuracy, allowing them to re-calibrate their energy budgets on a rolling, monthly basis. For the purposes of nancial planning, and to avoid unpleasant surprises, situating performance in its short-term context is just as important as looking at pre-construction estimates and long-term averages.
In the absence of reliable data, it may be tempting to label unexplained di erences in asset and portfolio performance as weather impacts. To deal with the impact of resource uctuations on budgets, however, it’s vital to seek a greater level of detail to support nancial reporting.
