Synthesis Area plus power estimate concatenation

Hello guys, 

I am currently working on a project where I synthetize thousands of small little combinatorial blocks. These blocks are similar and my purpose it is to find simply the best one for AREA and POWER. My current genus/rc script can do this easily for the AREA but I am struggling to find an efficient way to do the same with the power. 
My current script is the following:

***********************CODE**********************************

set_attribute information_level 2
set_attribute lib_search_path ../../libs
set_attribute library gf40.lib

read_hdl -sv -library WORK ../vlog/blocks0001.v

set DESIGN block0001000

elaborate $DESIGN
check_design -unresolved $DESIGN

set input_port_list { a }
set output_port_list { y }

synthesize -to_generic -effort high $DESIGN
synthesize -to_mapped -effort high $DESIGN

set area_design [get_attribute area $DESIGN]
set out [open "../rpt/blocks0001.rpt" w]
puts $out "Total gate_count $DESIGN : $area_design"
close $out

read_hdl -sv -library WORK ../vlog/blocks0001.v

set DESIGN block0001001

elaborate $DESIGN
check_design -unresolved $DESIGN

set input_port_list { a }
set output_port_list { y }

synthesize -to_generic -effort high $DESIGN
synthesize -to_mapped -effort high $DESIGN

set area_design [get_attribute area $DESIGN]
set out [open "../rpt/blocks0001.rpt" a]
puts $out "Total gate_count $DESIGN : $area_design"
close $out

.... and so on

****************************************************************

It compiles the verilog codes from one only generated file. The result is this:

***********************RESULT*****************************

Total gate_count block0001000 : 18.522
Total gate_count block0001001 : 18.522
Total gate_count block0001002 : 18.8748
Total gate_count block0001003 : 18.8748
Total gate_count block0001004 : 13.7592
Total gate_count block0001005 : 12.5244
Total gate_count block0001006 : 19.0512..... so on

**************************************************************

So all Area estimations are in the same report, very easily extractable. For the power I tried to the same with report_power and report_gates -power commands, but I cannot get any good result.
Do you have any suggestion about this?

P.S.
I am quite new with the cadence softwares so I know my question could sound a little bit silly and imprecise, so please ask for more details if you need it.
