All households in Delhi get 200 free units per month per meter, and
the next 200 units at 50%.
We have 2 meters (1 for lighting and 1 for power), so 400 free units and
400 more at half price.
This winter was a bit colder than usual so I exceeded the free allowance in
December on my power meter. and had to pay $15.
It also helps that our Govt was pragmatic and kept buying cheap oil from
Russia.

 The paper makes clear that one of the preferred technologies in

 This person would then answer questions from the PRC and possibly PNM

 I have several reasons for not wanting to see PNM make this huge

 don't sweat much about our electric bills (actually maybe if ours

Re: [FRIAM] Some brands of digital electric meters wildly inaccurate on nonlinear loads, and NM may get them soon!

2024-02-13 Thread Sarbajit Roy
Hi Bruno

Smart meters were mandated in New Delhi India in 2008 onwards and we had
the same sort of consumer experience with bills shooting up due to these
then "made in China" meters and there was tremendous consumer anger.

2 important changes were made for domestic consumers - a) Billing would be
on the basis of Kw-hr (resistive) and not on the basis of KVA-hr
(reactive). and b) The neutral wiring and meter connection would be through
a bus-bar system only (no looping of neutrals) and ELCBs were
made mandatory for preventing earth leakages. That greatly sorted out the
problem.

I believe the meter design was also changed to ensure that the Hall sensors
were inserted into the phase as well as neutral lines.

Here are some links.

https://www.derc.gov.in/sites/default/files/Public%20bulletin-5.pdf

https://www.derc.gov.in/sites/default/files/TechnicalspecificationforMeters_0.pdf

https://www.derc.gov.in/sites/default/files/Draft-Regulations.pdf
(for Page 16 of 80)

Just for your information, In the past 1 year I have paid a grand total of
about US$ 150 in electricity bills for an annual consumption of about 3,600
Kw-Hr (3,600 units).

> The paper makes clear that one of the preferred technologies in electric
> meters (the Rogowski coil)
> can go haywire when nonlinear loads are present. The smart meters gave
> readings up to 500% higher
> than the actual usage. The meters PNM has proposed for its entire
> territory is the Itron "Gen5" Riva,
> which has been deployed in the last 2 years in Denver and parts of Texas.
> Sure enough, some customers'
> bill have gone way up (3 or 4-fold in one news report), and they have
> little recourse: https://www.youtube.com/watch?v=dpOhTXV59pI=20s

> I intervened in this PRC proceeding last year, and may be able to get this
> info onto the record, and try to
> get the PRC to require better testing on nonlinear loads. But I need
> someone with some relevant expertise
> (can be education or experience) to explain the published findings and
> their implications to the PRC in an affidavit by March.
> This person would then answer questions from the PRC and possibly PNM via
> zoom in a short hearing in late April or May.

> I have several reasons for not wanting to see PNM make this huge
> investment (and by law they are entitled to a nice
> rate of return paid by us, the customers) in a very messed-up technology.
> Probably most of us in this group
> don't sweat much about our electric bills (actually maybe if ours
> quadrupled, we would), but for low-income families, this is
> potentially very cruel, since the cost of the meters will be charged with
> interest regardless of usage, and energy-saving
> appliances typically have nonlinear load usages).

> I hope to be at the St. John's gathering Friday am, but feel free to reply
