I cannot imagine that a trillion electron volts means anything at all without knowing the current. Since Power = Voltage X Current then a trillion volts with no current can do nothing at all.
The electron volt is a unit of energy. It is the amount of energy that an electron gains when it is accelerated by a one volt potential difference. See www-spof.gsfc.nasa.gov/Education/wgloss.html or amsglossary.allenpress.com/glossary/browse or vega.bac.pku.edu.cn/~wuxb/agn/text.html.
