An increasing number of high-power laser laboratories are being established with the aim of developing laser-plasma accelerators. Here a short overview is given on the preliminary results obtained in the self-injection test experiment as a part of the commissioning phase of the 220 TW FLAME laser facility. For laser energies on target below 1 J and pulse durations around 30 fs, accelerated electron bunches had an energy up the hundred MeV range, showing a significant degree of collimation below 10 mrad, in agreement with similar published results and confirming the expected laser performance at this energetic level. A correlation between electron collimation and upshift on laser transmitted light was also observed.
