Item  1.  Changes in Control of Registrant.

         In December of 2000, Reliable Power Systems, Inc., a Colorado
corporation ("Reliable"), approached Dencor Energy Cost Controls, Inc. (the
"Company") concerning a possible merger of the Company and Reliable. Reliable is
a start-up company with a dynamic business plan and access to necessary funding
to execute on that business plan. Reliable plans to become a supplier of energy
management and production devices for its commercial and industrial customers.
On February 7, 2001, Reliable merged into the Company's wholly owned subsidiary
in exchange for 94.7% of the voting control of the Company. This equity
consisted of 12,600,000 shares of common stock and 3,348,000 shares of Series A
Convertible Preferred Stock. Each share of the Series A Convertible Preferred
Stock converts into 50 shares of common stock and is entitled to 50 votes.

On February 7, 2001, as a condition of the transaction described above, Theodore
Hedman resigned as a director. This resignation was effective immediately. The
remaining directors then elected Thomas J. Wiens to serve Mr. Hedman's remaining
term and appointed him as Chairman.
