                    NOTIFICATION
    With reference to the transactions (a) proposed in the
Application-Declaration on Form U-1, as amended, in the above docket filed
by Cinergy
Corp., a Delaware corporation ("Cinergy"), a registered holding company
under the Public Utility Holding Company Act of 1935 (the "Act"), Cinergy
Investments, Inc., a Delaware corporation and direct, wholly-owned
nonutility subsidiary of Cinergy ("Cinergy Investments"), and Cinergy

company subsidiary of Cinergy ("Cinergy Services") and (b) authorized by
the Commission in its order dated February 7, 1997, Rel. No. 35-26662,
Cinergy Services hereby provides the following information:

1.  The following summary, covering the quarterly period ended June 30,
1998 ("Second Quarter 1998"), updates the business activities of Cinergy
Solutions, Inc. ("Cinergy Solutions"), a Delaware corporation and direct,
wholly-owned nonutility subsidiary of Cinergy Investments, as previously
reported in this file:

    a.   Energy Management Services.   Cinergy Solutions discontinued the
marketing of its "On-Site Energy Manager" program, previously described in
this file.

    b.   Asset Management Services.    Cinergy Solutions discontinued the
marketing of its large and small asset management services, previously
described in this file under the rubrics "Customized Cinergy Solutions"
("CCS") and "Energy Project Services" ("EPS").  Rather, in the future,
another Cinergy nonutility subsidiary, Cinergy Business Solutions, will
market utility asset management services, including the full scope of
services previously marketed by Cinergy Solutions under CCS and EPS, but
with a greater attention to tailoring projects to address the customer's
specific energy needs.  Finally, in the Second Quarter 1998, Cinergy
Solutions continued marketing transmission and distribution engineering,
procurement and construction services to municipals, cooperatives,
universities and certain governmental entities (collectively, "T&D
Services").  Specific T&D Services include construction of transmission and
distribution lines, procurement of materials, construction of substations,
complete turnkey projects, and project management.

    c.   Consulting Services.  Nothing to report, except to the extent
included within the other activities described herein.

    d.   QF Project Development and Ownership.  See Cinergy's Quarterly
Reports on Form U-9C-3 for information concerning the joint venture with
Trigen Energy Corporation.

    e.   Consumer Services.  In partnership with an outside provider,
Cinergy Solutions continued offering to residential customers on a pilot
basis a service contract program (called "Appliance Protection Plus")
covering parts and labor for mechanical breakdowns of existing appliances
and HVAC systems.  

    f.   Customer Financing.  In tandem with a bank, Cinergy Solutions
continued marketing "Quick Credit," a financial services program providing
residential, commercial, and institutional customers with financing for
retrofit or replacement of their HVAC systems and other types of
energy-related projects.
    
    g.   Third-Party Alliances.  See Cinergy's Quarterly Reports on Form
U-9C-3 for information concerning the joint venture with Trigen Energy

cost of approximately $1,633,000.  During that same period, The Cincinnati
Gas & Electric Company and PSI Energy, Inc. provided engineering and
construction and project management services to Cinergy Solutions totaling
approximately $22,000 and $113,000, respectively.

Investments guaranteed any financial obligations of Cinergy Solutions. 
During the Second Quarter 1998, Cinergy Investments made net open-account
advances to Cinergy Solutions totaling $3,947,481.40 at annual interest
rates ranging from 5.96% to 5.99%.

4.  During the Second Quarter 1998, Cinergy Solutions did not enter into
any long-term contract by which Cinergy Solutions performs long-term
