Drawing a Power Flow arrow in circuitikz

Question

Is it possible to draw a power flow arrow in circuitikz?

I'd like to draw an arrow point away from the voltage source on the right that indicates the flow of power towards the left.

What I'm after is not a current arrow, but a larger arrow that sits above the circuit instead of on the wire.

Thanks in advance!

\begin{circuitikz} \draw
(0,0)   to [sV, l=$V_{\text{upstream}}$] (0,2)
        to [R, l=$R$] (2,2)
        to [L, l=$X_l$] (4,2)
        to [sV, l=$V_{\text{DG}}$] (4,0)
        -- (0,0);
;\end{circuitikz}

You can use the \draw command from TikZ to place the arrow at the desired location:

\documentclass{article} 
\usepackage{amsmath}
\usepackage{circuitikz}

\begin{document}

\begin{circuitikz} \draw
(0,0)   to [sV, l=$V_{\text{upstream}}$] (0,2)
        to [R, l=$R$] (2,2)
        to [L, l=$X_l$] (4,2)
        to [sV , l=$V_{\text{DG}}$] (4,0)
        -- (0,0);
\draw[-latex] (2.5,0.5) -- (1.5,0.5);
\end{circuitikz}

\end{document}
