Missing powershell commands for excelservice in SharePoint 2013

Hi all

I have a problem with accessing all the excelservice-commands in SharePoint 2013. Is there any way to access them?

It's an serverfarm installation with AutoSPInstaller. SharePoint 2013 Enterprise, Windows server 2012 and SQL server 2012 SP1.

I'm trying to configure PowerPivot for SharePoint 2013 and I have followed this TechNet articlehttp://technet.microsoft.com/en-us/library/jj218792.aspx but it's failing because I cant access the command Get-SPExcelServiceApplication.

Clik here to view.

Any sugestions? Anyone?

Best Regards
