Nordic has provided a good SPP implementation over BLE.
However, will it raise power consumption and cause BLE to lose its low-power characteristics? If yes, is it because the connection is always on like in Bluetooth Classic SPP?

BLE connections always consume lower power than similar setup in BR/EDR, when you use UART port emulation then two more modules inside the chip are enabled (UART = GPIOTE). UART consumes about 0.2mA current and GPIOTE consumes about 1mA (on revision 3 only IN events consume 1mA and out event consumes only 1 uA)
look into this post and reply from Stefan for current consumption of GPIOTE devzone.nordicsemi.com/.../
Apart from this consumption there is no change in the power characteristics of BLE with this setup
