       Form 10-K for Fiscal Year Ended December 31, 2021

       General

   1.                                                   We note that you
provided more expansive disclosure in your Climate Report 2021 than
                                                        you provided in your
SEC filings. Please advise us what consideration you gave to
                                                        providing the same type
of climate-related disclosure in your SEC filings as you provided
                                                        in your Climate Report
2021.
       Risk Factors, page 14

   2.                                                   Disclosure in your Form
10-K appears to identify    evolving investor sentiment related to
                                                        the use of fossil fuels
   as a transition risk related to climate change. Please revise to more
                                                        clearly describe the
material effects of this transition risk beyond what is currently
                                                        characterized as the
significant impact on our electric generation and natural gas
                                                        businesses in the
future.

3.       Disclose any material litigation risks related to climate change and
explain the potential
         impact to the company.

Operations, page
35

4.       Please tell us about your disclosure considerations related to
material past and future
         capital expenditures for climate-related projects. For example,
disclosure in your Form
         10-K refers to replacement projects that    reduce, or potentially
reduce, greenhouse gas
         emissions.    Include quantitative information for the periods for
which financial
         statements are presented in your Form 10-K and amounts budgeted for
future periods as
         part of your response.
5.       On page 22 of your Form 10-K, you state that climate change is
exacerbating the risks to
         your physical infrastructure by increasing the frequency of extreme
weather. Please
         quantify for us weather-related damages to your property or operations
during the periods
         covered by your Form 10-K and in subsequent periods. In addition,
please revise to
         discuss the potential for indirect weather-related impacts that have
affected or may affect
         your major suppliers.
6.       You disclose on page 17 that some insurers are moving away from
underwriting certain
         carbon-intensive energy-related businesses such as those exposed to
certain perils such as
         wildfires. Provide us with additional detail regarding weather-related
impacts on the cost
         or availability of insurance (e.g., whether the premiums you pay for
insurance coverage
         have significantly increased due to weather conditions). Please
include quantitative
         information with your response for the periods covered by your Form
10-K and explain
         whether you expect to incur increased amounts in future periods.
7.       We note your disclosure on page 30 stating that revised or additional
laws and regulations
         may result in increased compliance costs. Please tell us about and
quantify compliance
         costs related to climate change for each of the periods for which
financial statements are
         presented in your Form 10-K and whether increased amounts are expected
to be incurred
         in future periods.
8.       If material, provide disclosure about your purchase or sale of carbon
credits or offsets and
         any material effects on your business, financial condition, and the
results of operations.
         To the extent applicable, provide quantitative information with your
response for each of
         the periods for which financial statements are presented in your Form
10-K and for any
         future periods.
        We remind you that the company and its management are responsible for
the accuracy
and adequacy of their disclosures, notwithstanding any review, comments, action
or absence of
action by the staff.
