Allen Nye
Chief Executive and Director at Sempra
Yes. Thanks, Jeff, and thanks, Jeremy. I think Jeff covered it to a large degree, but let me just give you a little bit of color. With regards to why now, it's exactly what Jeff said. I mentioned at the Investor Day that we had a need to go to our Board in July to increase our expectations for 2022 in order to get ahead of the game, to make sure we had the resources and the equipment to actually execute next year.
And so as Jeff said, we did that. We raised '22 from what we previously said was 2.4 to 2.5 up to 2.8. We also took this opportunity to let you all know that we're seeing some opportunities this year, and so we've upped our 2021 from 2.4, which is what we previously had told you all, to 2.5.
And then just given the fact that we're going to go ahead and talking about increasing '21 and '22, we had the opportunity to discuss with our Board, things we're seeing some of this growth that Jeff is talking about. And so we've been spending a lot of time on capex here at Oncor because of what we're seeing.
And what we're seeing is, to Jeff's point, and Trevor talked about it earlier, premise growth last year, we had the largest organic growth rate ever in our company's history. And we're on pace this year through two quarters. Both quarters this year were higher than the corresponding quarters last year. Transmission points of interconnection on both the retail and the generation side are above the levels end of year last year and above the similar quarters of last year.
The economic development, which I think is in Trevor's earlier remarks, economic development's another thing we look at. Request for information, which are basically project location-specific discussions we're having with potential builders, are up 72% approximately year-over-year.
And then I always talk about West Texas when we're talking about growth. The West Texas story continues to be really strong. The latest trend is electrification of fields, people considering ESG ramifications, emissions. So we're getting some uptick there, but we have another peak on our Culberson Loop transmission system, in July, hit 760 megawatts versus 678 last year. That's an all-time high.
Another peak in the Far West Texas weather zone in June. So we're seeing growth all over our system, really strong, which leads to these capex discussions we're having. And since I told you all at the investor call -- or investor meeting that we are going to address '22 with our Board in July. And since we've adjusted '21 up, we thought now is a good opportunity to just provide you all with our expectations as a management team of what we're seeing with regard to those outer years.
And those outer years, as you can see in our documents are, we're looking at 2.7 to 3.0 for the four years of the -- outer years of the plan. And that's our expectation right now. But as Jeff said, we're going to go into October, like we always do, and have our meeting on our five-year plan with our shareholders and with our independent directors and with our Board.
And we're going to review the information available to us at that time. And we'll have a number then, it may be 14, it may be something else. We feel very good about 14 right now. And we'll see where we are when we get to October and we'll have something to announce after that.
To Jeff's point as well, we added about $1.8 billion to our five-year expectation right now. The incremental capital that we have talked about in previous meetings and investor calls, in the range of $775 million[Phonetic] to $1.275 billion[Phonetic], which I think was on Page 45 of the investor deck, last time we talked, that remains available.
We have -- sometimes, we move projects from that incremental kind of bucket into our capex plan, sometimes they have capex that comes from outside that incremental bucket, and it goes into our plan.
But notwithstanding the fact that we've raised to, right now our expectation to around $14 billion over five, there are significant -- there remain significant opportunities to invest on our system and those additional opportunities are in part reflected in that incremental capex bucket that we discussed before. I'll be glad to answer any questions, so thanks a lot.
