Hi,
For power estimation, Altera provides two tools. The most accurate estimates are obtained from the Quartus II Power Play Power Analyzer (as mentioned by Ben), especially if you provide simulation vectors. We also have an Early Power Estimator spreadsheet that can be used for estimates pre-HDL; once you have a design, you're better off estimating the power in Quartus.
As of Quartus II 5.1, Quartus will perform push-button dynamic power optimization. It does this by reducing the capacitance of highly toggling nets in your design, and by restructuring RAM and other logic. Results vary depending the type of design, how tight your timing constraints are (the tool will do its best to continue to meet timing), the power optimization effort level you set, and the availability of simulation vectors (you don't need them thought to get some benefit). For designs with some timing margin and simulation vectors, we see on average 25% reduction in dynamic power as compared to the same designs compiled in earlier versions of Quartus II.
You can find some tips on optimizing the dynamic power of your design and how to run Quartus to analyze and optimize your power at:

And I wouldn't be doing my job if I didn't mention that Cyclone II has lower static power, lower dynamic power, and lower I/O than any competing device, so its certainly worth your time to check it out.
