Nice! Looks like an old PC on that one on the right. Must be expensive to rent these from NGrid. I've seen the rental tariff for RI and the prices they charge for rental floods and cobraheads are pretty expensive. $150 a year for a 400W HPS flood (that's not including the kWh charge). In two years you'll have saved enough to buy your own flood light lol. NGrid sure doesn't put $150 a year into maintenance. They spend $80 every five years to send a guy out with a bulb to fix the light ever five years.
NGrid has never maintained the 1000W MV flood lights here in RI. Any left haven't been serviced since 1998. They charge around $120 a year plus kWh charge per fixture. Assuming there are 100 of these 1000W MV flood lights in RI (just for a round number) that's $228,000 in pure profit NGrid has raked in just from 100 flood lights they've never touched in the 19 years they've owned them. For HPS flood lights, they charge around $150/year. Assuming the bulbs last five years (some last longer, some shorter) and assuming they get the lamps for about $10 a piece and the lineman spends 15 minutes per light and gets paid $80 an hour, that's about $6 a year NGrid spends to maintain the fixture if you spread the $10 lamp cost and $20 lineman pay (quarter of an hour spent on the light). So that's $144 of profit per year per flood light. Assuming there are 500 400W HPS rental flood lights in RI owned by NGrid that's $7200 per year. Now, the fixtures do cost money up-front. Assuming each flood light costs NGrid $200 a piece new (being a fairly large utility they order in massive quantities, so they get a lower price than one of us would) and that the fixtures last 10 years on average, that subtracts $200 every 10 years, or $20 a year per light.
So that drops the profit down to $124/year per fixture, or $1240 over the assumed 10 year lifespan of the fixture. Times that by the assumed 500 flood lights they may have in RI and that's $620,000 over a ten year period. Some serious money! Many of the HPS fixtures were installed in the 90s before NGrid took over too, so they never spent that initial cash on the fixtures, I'm amazed they're so eager to practically give away this sort of revenue to municipalities to put up LEDs. You'd think for all this money they rake in they'd do a better job maintaining the fixtures lol. I see dead lights all over the place and lights with doors taped shut because the hinge snapped or latch doesn't have enough spring tension. I mean, the city pays enough money to deserve a new fixture at that point.
