Business Premium comes with Power Pivot?

I am trying to find out if the o365 Business Premium pricing plan ($2.20 per month) comes with Power Pivot.

https://products.office.com/en-au/nonprofit/office-365-nonprofit-plans-and-pricing 

 I rang the support desk and was told "Business Premium is a 'business plan' so yes it does".  But what concerns me is down the bottom of the page above it talks about Professional Plus for $3.19 per month, and I know that you normally have to purchase Professional Plus to get Power Pivot.

Can anyone definitely tell me if o365 Business Premium for Non Profits includes Power Pivot?  Also does the SharePoint Online version that ships with Business Premium support Power Pivot workbooks (up to 10MB?)

Thanks
