Why aren't any buildings coming up on my break-out Industrial area despite having demand in Cities: Skylines

I'm trying to expand my city's industrial footprint. Acquired the second square besides the first "main square" & I'm trying to build an industrial district around there.

My City has adequate demand for Industries, yet no buildings seem to come up in the second Industrial hub. Why is this so? What can I do to get those buildings up and running?

Solution 1:

Actually, this is because the breakout region wasn't connected by a power source. I realized this by putting in a better access system, as mentioned by MBraedley. Despite the access, the Industrial buildings weren't coming up.

After connecting the power lines, the Industrial buildings started coming up immediately.

To reconfirm this is the problem, I went back to my original save without the improved access and drew power lines - and the Industries came up almost immediately.
