OPPD Bellevue Substation

OPPD Bellevue Substation
This is an unusual (for Nebraska) in-line 69-kv substation! The tower line runs through it, while the former 115-kv line terminates here.

That's different! So the switchgear would be inside the hut here? Seems to be a bit big just to have the instrumentation.

OPPD likes to install their 13.8-kv switchgear in large metal enclosures. There is also a manufacturer in town who builds such enclosures for power utilities. I think it is called Pederson Power Equipment.

Talk about a big sub there! Also interesting to see that OPPD uses the same transmission voltages as Connecticut Light & Power: 69kv and 115kv. CL&P's transmission originally ran at 66000, but as loads increased, they hooked up their 66kv cans in Y and bumped the line voltage up to 115,000.

Actually OPPD uses 69-kv and 161-kv transmission voltages. However, Bellevue was a point where NPPD and its predecessors overlapped the OPPD service area. In the mid-1940s many Omaha business people expressed dislike for the idea of "outsiders" from Columbus, Nebraska taking over the Nebraska Power Company. Therefore, an independent and unique OPPD was formed. Apparently OPPD wires its transmission lines differently, and utilizes autotransformers in their substations. That is what I have been told. I will try to get some pictures of the 1950s dual-circuit 161-kv tower line in the next few days.

The Nebraska Power Company mainly used 66-kv transmission lines starting in the mid-1920s, running them to Valley, Ashland, and Louisville as NPCo purchased neighboring utilities, like the Platte Valley Electric Company in Valley and the Omaha & Lincoln Railway & Light Company.
The Nebraska Power Company also followed the practice of using a small number of large efficient power plants, its main generating station being the Jones Street Power Plant. The South Omaha Power Plant was a peaking station and district heating plant, supplying steam to the large meat packing plants located near the Stockyards. My wife's uncle Jim worked for OPPD at South Omaha firing the boilers, starting in the late 1940s and retiring in the early 1970s.

In 1949 there had been arguments between the Consumer's Public Power District and the Nebraska Public Power System concerning the construction of new generating capacity. Therefore, the Central Public Power and Irrigation District funded the construction of a large coal-fired power plant at Bellevue, the Kramer Station. 115-kv transmission lines were then run to Fremont, Columbus, and Lincoln from a large switchyard in Sarpy County.
