There's way more here than just about AXPW ... its partner in their press release said among other things:
With the new rules in place, Axion Power will be able to participate initially in the PJM regulation market as a 100kw resource that will eventually be ramped to higher kw levels. Through active participation in the wholesale market, Axion Power International will be able to earn new revenues through Viridity’s proprietary VPower System, which integrates, supports and optimizes the real-time dispatch of distributed energy resources and flexible load in the wholesale market.
“One of the most exciting elements of the FERC decision is that by reducing the barriers to get into the marketplace, systems will have the opportunity to grow and begin to generate revenue,” said Audrey Zibelman. “Looking forward, a similar system that has the opportunity to grow in the marketplace and increase to higher kw levels has enhanced opportunities for revenue generation. As an example, based upon historic prices, a 1 MW resource could achieve a projected revenue between $160,000 to $240,000 on a yearly basis.”
