金德摩根告诉客户，计划从 5 月 7 日至 12 日减少二叠纪公路管道的流量，并从 5 月 14 日至 21 日减少墨西哥湾沿岸快线管道的流量。

过去一个月左右的时间里，二叠纪地区这些管道和其他管道的减少，帮助将 Waha 价格在 3 月和 4 月的几天内推低至零以下。

二叠纪是美国最大的产油页岩盆地。许多天然气也随着石油一起从地下涌出。

当油价相对较高时，就像最近几周那样，生产商愿意承担天然气损失，因为他们仍然可以通过石油销售赚很多钱。

负天然气价格也压低了电价，因为无法将天然气运送到墨西哥湾沿岸的托运人试图将更多燃料运送到西海岸。这有助于降低加利福尼亚州和亚利桑那州本已很低的电价，因为大部分廉价天然气用于发电。

春季电力和天然气价格普遍较低，因为温和的天气使供暖和制冷需求较低。在西海岸，温暖的春季天气也融化了山上的冬季积雪，增加了廉价水力发电的供应。

Kinder Morgan told customers it planned to reduce flows on its Permian Highway Pipeline from May 7-12 and its Gulf Coast Express pipe from May 14-21.

Reductions over the past month or so on those and other pipes in the Permian region helped push Waha prices below zero for several days in March and April.

The Permian is the nation’s biggest oil producing shale basin. A lot of gas also comes out of the ground along with the oil there.

When oil prices are relatively high, like they have been in recent weeks, producers are willing to take a loss on gas because they can still make lots of money on their oil sales.

The negative gas prices have also pushed down power prices as shippers who are unable to flow the gas to the Gulf Coast try to move more fuel to the West Coast. That helps cut already low electric prices in California and Arizona because much of that cheap gas is used for power generation.

Power and gas prices are generally low in the spring because mild weather keeps both heating and cooling demand low. On the West Coast, warmer spring weather also melts the winter snow in the mountains, boosting the supply of cheap hydropower supplies.
