Since  WGL,SEMCO,ENSTAR   are utilities that supply natural gas to its customers, heating days would  be a quick measure of Altagas’s  performance  for  the quarter  when compared  to last year. (Altagas uses a 30 year  heating day average in the purchase of natural gas for storage to serve its customers)

Since  the ultilies  are separated by vast distances , I categorized the areas into 3 and calculated the heating days for the 3 regions.   Given that the regions have  different customer base,  one uses  a weighted distribution to determine the overall effect of heating days on all 3 regions (similar to center of mass).

Data is taken from the website below.

Since  the Washington , Michigan areas have  increased heating days as compared to last  year’s quarter,  I would expect increased revenues from the utilities  for this quarter.  Enstar  shows a  decrease but  its customer base is significantly lower than that of Washington and Michigan areas.

Customer growth is typically 1%  per year.

% change Between qtrs 20/21   9.60%  
           

Results indicate  a 9-10%  increase in the weighted heat days for Altagas so  I  would expect  a similiar increase in revenue generated from the usage of natural gas.

Upcoming earnings...hmmm
The AltaPumpers are at it again I see. What about that mild to non-existant winter weather in the northeast US? Much-needed WGL performance won't be much good for Q1 earnings this year.
