One of the changes in EnergyPlus 8.6 was that the the tabular reports related to economics need to be explicitly requested. In EnergyPlus 8.5 and prior, the use of the UtilityCost:Tariff object triggered to creation of the TariffReport and EconomicResultSummary report. In 8.6 this was changed. The OutputChanges8-5-0-to-8-6-0.md file that in c:\EnergyPlusV8-6-0 describes it as:

Economics, Tariff, and Life Cycle Cost Reports Explicitly Requested

The Economics Results Summary Report, Tariff Report, and Life-Cycle Cost Report now need to be specifically requested rather than being automatically generated if specific objects are present in the file. To get the reports individually use EconomicResultSummary, TariffReport, and LifeCycleCostReport respectively in the Output:Table:SummaryReports object. These are also available when using any of the AllSummary options. The reports are unchanged just they way of generating them has changed.

See 5598.

So to show the reports, you need to add a request for those reports explicitly:

Output:Table:SummaryReports,
    AnnualBuildingUtilityPerformanceSummary,  !- Report 1 Name
    SystemSummary,           !- Report 2 Name
    EquipmentSummary,        !- Report 3 Name
    InputVerificationandResultsSummary,  !- Report 4 Name
    HVACSizingSummary,       !- Report 5 Name
    ComponentSizingSummary,  !- Report 6 Name
    ClimaticDataSummary,     !- Report 7 Name
    EnergyMeters,            !- Report 8 Name
    Standard62.1Summary,     !- Report 9 Name
    TariffReport,
    EconomicResultSummary;

Of course you can always just request all reports to be created by using:

  Output:Table:SummaryReports,
    AllSummary;              !- Report 1 Name

In general, the OutputChanges*.md file is a good file to scan for each new version of EnergyPlus. It was originally intended to help interface developers but I think it would be useful for most users to look at also.
